                 Subject to Completion, dated December 20, 1996

                                1,828,495 Shares


                               AVANT! CORPORATION

                                  Common Stock

                                -----------------

         This  Prospectus  relates  to the public  offering,  which is not being
underwritten,  of 1,828,495  shares (the  "Shares") of Common Stock,  $.0001 par
value (the "Common  Stock") of Avant!  Corporation  ("Avant!" or the "Company").
The Shares are  outstanding  shares  that may be sold from time to time by or on
behalf of certain stockholders of the Company (the "Selling Stockholders").  The
Selling  Stockholders  acquired the Shares in a private transaction in which the
Company acquired FrontLine Design Automation, Inc.

         The Shares may be offered by the Selling Stockholders from time to time
in transactions in the  over-the-counter  market, on the Nasdaq National Market,
in privately  negotiated  transactions,  or by a combination  of such methods of
sale, at fixed prices that may be changed,  at market  prices  prevailing at the
time  of  sale,  at  prices  related  to such  prevailing  market  prices  or at
negotiated  prices.  The Selling  Stockholders  may effect such  transactions by
selling  the Shares to or through  broker-dealers  and such  broker-dealers  may
receive  compensation in the form of discounts,  concessions or commissions from
the  Selling  Stockholders  or  the  purchasers  of the  Shares  for  whom  such
broker-dealers may act as agent or to whom they sell as principal or both (which
compensation  to a  particular  broker-dealer  might be in excess  of  customary
commissions). See "Selling Stockholders" and "Plan of Distribution."

         The Company will not receive any of the  proceeds  from the sale of the
Shares by the  Selling  Stockholders.  The  Company  has agreed to bear  certain
expenses in connection with the  registration of the Shares being offered by the
Selling  Stockholders.  In  addition,  the Company has agreed to  indemnify  the
Selling  Stockholders  with respect to the Shares offered hereby against certain
liabilities,  including certain liabilities under the Securities Act of 1933, as
amended  (the  "Securities  Act"),  or, if such  indemnity  is  unavailable,  to
contribute toward amounts required to be paid in respect of such liabilities.

         On  December  16,  1996,  the average of the high and low price for the
Company's  Common  Stock was $29.25  per share. The  Company's  Common  Stock is
traded on the Nasdaq National Market under the symbol "AVNT."

                         -------------------------------

         The  Selling   Stockholders  and  any  broker-dealers  or  agents  that
participate with the Selling  Stockholders in the distribution of the Shares may
be deemed to be  "underwriters"  within  the  meaning  of  Section  2(11) of the
Securities  Act,  and any  commissions  received  by them and any  profit on the
resale  of the  Shares  purchased  by  them  may be  deemed  to be  underwriting
commissions or discounts under the Securities Act.

                         -------------------------------

         THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK.

including those set forth in "Risk Factors" and elsewhere in this Prospectus. In
evaluating  the  Company's  business,   prospective  investors  should  consider
carefully the following  factors in addition to the other  information set forth
in this Prospectus and incorporated by reference herein.


Litigation Risk

         On December 6, 1995, Cadence Design Systems,  Inc. ("Cadence") filed an
action against Avant!  and certain of its officers in the United States District
Court for the Northern District of California  alleging copyright  infringement,
unfair  competition,  misappropriation of trade secrets,  conspiracy,  breach of
contract, inducing breach of contract and false advertising.  The essence of the
complaint is that certain Avant!  employees who formerly were Cadence  employees
misappropriated   and  improperly  copied  source  code  for  certain  important
functions of Avant!  place and route products from Cadence,  and that Avant! has
competed  unfairly  by  making  false  statements  concerning  Cadence  and  its
products.  The action  also  alleges  that  Avant!  induced  certain  individual
defendants to breach their  agreements of employment  and  confidentiality  with
Cadence. In addition to actual and punitive damages, Cadence seeks to enjoin the
sale of  certain  place  and route  products  and has filed a motion to obtain a
preliminary  injunction pending trial of the action. Avant! filed its opposition
to  Cadence's  motion  on June  28,  1996.  Cadence  filed a reply  to  Avant!'s
opposition on August 27, 1996. The preliminary  injunction hearing took place on
September  10, 1996.  No ruling on the  preliminary  injunction  motion has been
issued as of the date hereof.

         On January 16, 1996,  Avant!  filed a counterclaim  alleging  antitrust
violations,  racketeering,  false advertising,  defamation,  trade libel, unfair
competition, unfair trade practices, negligent and intentional interference with
prospective  economic  advantage and intentional  interference  with contractual
relations.

         The Santa Clara County District Attorney's office also is investigating
the  allegations  of  misappropriation  of trade  secrets set forth in Cadence's
lawsuit,  described above. On December 5, 1995, a search warrant was executed at
Avant!'s Sunnyvale, California, facility to determine whether there was evidence
of  criminal  conduct.  No  criminal  charges  have been filed  against  Avant!,
Avnat!'s  management or its  employees,  but no assurance can be given that such
charges will not be filed in the future. A criminal complaint,  if filed against
Avant!,  Avant!'s  management  or its  employees,  could  result  in a  loss  of
management and other personnel and could have other material  adverse effects on
the Company. On each of December 15 and 19, 1995, class action filings were made
against Avant!  alleging certain  securities law violations,  including omission
and/or  misrepresentation  of  material  facts.  The  alleged  omissions  and/or
misrepresentations  are largely consistent with the allegations  outlined in the
Cadence claim.

         It is Avant!'s position that the plaintiffs'  claims are without merit.
Avant!  believes it has sufficient defenses to all of the plaintiffs' claims and
intends  to  defend  itself  vigorously.  If,  however,  Avant!'s  defenses  are
unsuccessful,  Avant!  may be  enjoined  from  selling  certain  place and route
products and may be required to pay damages to Cadence. In such event,  Avant!'s
business,   operating  results  and  financial  condition  would  be  materially
adversely affected. In particular, Avant!'s place and route products in dispute,
ArcCell-BV  and  ArcCell-XO   (which  have  been  replaced  by  Aquarius-BV  and
Aquarius-XO),  accounted for  approximately  20% of Avant!'s total  supplemental
consolidated revenues for the three-year period ended December 31, 1995.

                                       4

<PAGE>

In addition,  it is likely that an adverse judgment against Avant!  would result
in a steep  decline in the market  price of Avant!  Common  Stock.  Although the
Company  believes,  based  on  information  it  presently  possesses,  that  the
conclusion  of these  claims  will not have a  material  adverse  effect  on the
Company's  supplemental  consolidated   financial  position,  there  can  be  no
assurance that an adverse judgement,  if granted,  in any claim would not have a
material  adverse effect on the Company's  business,  supplemental  consolidated
financial position, or supplemental consolidated results of operations.

         In the opinion of Avant! management,  based on information it presently
possesses,  the  conclusion  of these  claims  will not have a material  adverse
effect on Avant!'s supplemental consolidated financial position.

         Meta has a long-standing  technology relationship with Cadence pursuant
to which, among other things, Meta and Cadence  cross-license certain aspects of
their  respective  technologies  including  Meta's  MASTER  Toolbox  and  HSPICE
products in order to develop certain  interfaces  between Cadence's products and
Meta's selling and supporting such products.  Meta licenses  Cadence's  maskwork
layout  software for use by  Meta-Labs  services for  generating  maskworks  for
MetaTestchip. In light of Avant!'s pending litigation with Cadence, it is almost
certain that Cadence will sever its  relationship  with Meta  following the Meta
Acquisition.  In such event,  Meta would  experience  delays in  generating  new
MetaTestchips as a result of the need to transition to Avant!'s layout software.
Further,  Meta currently  integrates a portion of Cadence technology with HSPICE
to provide a data output format for Cadence's waveform viewing products and uses
certain  Cadence  products to provide Cadence product support for MASTER Toolbox
which may no longer be available at a reasonable  price or profit after the Meta
Acquisition.  Additionally,  Cadence sells Spectre circuit  simulation  software
which directly competes with Meta's HSPICE product. Accordingly,  termination of
Meta's  relationship  with Cadence could have a material adverse effect upon the
Company's business, operating results and financial condition.

         The preceding pending  litigation and any future litigation against the
Company or its  employees,  regardless of the outcome,  is expected to result in
substantial  costs and  expenses  to the Company and  significant  diversion  of
attention by the Company's technical and management personnel.  Accordingly, any
such litigation could have a material adverse effect on the Company's  business,
operating results or financial condition.


Uncertainty Relating to Integration of Operations and Product Lines;  Management
of Growth

         The  integration  of  Anagram's,  Meta's and  FrontLine's  business and
personnel presents difficult challenges for Avant!'s management. Each of Avant!,
Anagram, Meta and FrontLine entered into their respective merger agreements with
the expectation that their merger will result in synergies for the Company.  The
Company,  however, is more complex and diverse than either Avant!, Anagram, Meta
or FrontLine individually,  and the combination and continued operation of their
distinct business operations will be difficult.  While the management and Boards
of  Avant!,  Anagram,  Meta  and  FrontLine  believe  that  the  contemporaneous
combination of Avant!,  Anagram,  Meta and FrontLine can be effected in a manner
that will realize the value of the Company,  the management group of the Company
has limited experience in combinations of this complexity or size.  Accordingly,
there  can  be no  assurance  that  the  process  of  effecting  these  business
combinations can be effectively managed to realize the synergies  anticipated to
result therefrom.

         Following the acquisition of Anagram, Meta and FrontLine (collectively,
the "Acqusitions"), in order to maintain and increase profitability, the Company
will  need to  successfully  integrate  and  streamline  overlapping  functions.
Avant!,  Anagram,  Meta and FrontLine each have different systems and procedures
in many operational areas that must be rationalized and integrated. There can be
no  assurance  that  such   integration   will  be   accomplished   effectively,
expeditiously  or  efficiently.  The  difficulties  of such  integration  may be
increased by the necessity of coordinating  geographically  separated divisions.
The integration of certain  operations  following the Acquisitions  will require
the dedication of management  resources that may temporarily  distract attention
from the  day-to-day  business of the  Company.  The business of the Company may
also be  disrupted  by  employee  uncertainty  and  lack of  focus  during  such
integration. Failure to effectively accomplish the integration of the operations
of Avant!,  Anagram,  Meta and FrontLine could have a material adverse effect on
the Company's  business,  operating results and financial  condition.  Moreover,
uncertainty  in  the  marketplace  or  customer   hesitation   relating  to  the
Acquisitions could negatively affect the Company's  business,  operating results
and financial condition.

         Avant!,  Anagram,  Meta and  FrontLine  entered  into their  respective
merger  agreements in order to achieve  potential mutual benefits from combining
each of their respective  expertise and product lines for the physical design of
high-density, high-performance ICs. Realization of these potential benefits will
require,  among other  things,  integrating  the  Company's  respective  product
offerings and  coordinating  the Company's  sales and marketing and 

                                       5
<PAGE>

research  and  development   efforts.   Failure  to  efficiently   achieve  such
integration  could have a material  adverse  effect on the  Company's  business,
operating results and financial condition.

         Each of Avant!,  Anagram, Meta and FrontLine has experienced periods of
rapid  growth  and  expansion  that  has  placed  and  will  continue  to  place
significant strains upon their respective  management systems and resources.  In
addition,  certain of the  Company's  senior  management  personnel  have worked
together  only  for a short  period  of time and  must  learn  to work  together
effectively.  The Company's ability to compete  effectively and to manage future
growth,  if any,  will require the Company to continue to implement  and improve
operational,  financial and management information systems on a timely basis and
to expand,  train, motivate and manage its work force. There can be no assurance
that the Company's personnel,  systems,  procedures and control will be adequate
to support the Company's operations.


Dependence Upon Key Personnel

          The Company's future operating results depend in significant part upon
the continued service of its key management and technical personnel.  Few of the
Company's employees are bound by employment or non-competition  agreements,  and
due to the intense  competition  for such  personnel as well as the  uncertainty
caused  by the  integration  of  Avant!'s,  Anagram's,  Meta's  and  FrontLine's
businesses,  it is possible  that the Company  will be unable to retain such key
technical and managerial personnel. There are only a limited number of qualified
ICDA engineers,  and competition for such individuals is intense. If the Company
is unable to attract,  hire and retain  qualified  personnel in the future,  the
development  of new  products  and the  management  of an  increasingly  complex
business  would  be  impaired,  which  would  materially  adversely  affect  the
Company's business, operating results and financial condition.  Additionally, if
a criminal complaint is filed against the Company,  the Company's  management or
any of its employees  relating to the matters  underlying the pending litigation
between Avant!  and Cadence,  thereby  resulting in a loss of Avant!  personnel,
then the Company's  business,  operating results and financial  condition may be
materially adversely affected. See "--Litigation Risk."


Competition

         The  ICDA  software  market  in  which  Avant!  competes  is  intensely
competitive and subject to rapid change. Avant! currently faces competition from
major ICDA vendors, including Cadence, which currently holds a dominant share of
the  market  for  IC  physical  design  software,  Mentor  Graphics  Corporation
("Mentor"),   Viewlogic  Systems  Incorporated  ("Viewlogic")  and  EPIC  Design
Technology,  Inc.  ("EPIC").  As the Company  expands its product  offerings  to
include other library  generation tools and other electronic  design  automation
("EDA") tools, it will compete  increasingly with these established EDA vendors.
Certain  of these  established  vendors  have a  longer  operating  history  and
significantly greater financial, technical and marketing resources, greater name
recognition and a larger installed customer base than the Company. Each of these
competitors  will  likely be able to respond  more  quickly  to new or  emerging
technologies  and  changes  in  customer  requirements  and  to  devote  greater
resources to the  development,  promotion  and sale of their  products  than the
Company.  Moreover,  the industry in which the Company  competes is undergoing a
trend toward consolidation that is expected to result in large, more financially
flexible  competitors  with a broad range of product  offerings.  In addition to
competition  from  EDA  vendors,   the  Company  also  faces   competition  from
semiconductor  companies that have internal design groups that develop their own
customized  place and route and simulation  tools for their own particular needs
and  therefore may be reluctant to purchase  products  offered by the Company or
other  independent  vendors.  There can be no assurance that the Company will be
able to compete  successfully  against  current and future  competitors  or that
competitive  pressures  faced by the  Company  will not have a material  adverse
effect on its  business,  operating  results  and  financial  condition.  If the
Company  is  unable  to  compete   successfully   against   current  and  future
competitors,  the Company's business,  operating results and financial condition
will be materially adversely affected.

Potential Fluctuations in Quarterly Results

         The quarterly  operating results of the Company may vary  substantially
from period to period  depending on factors  such as the outcome of  outstanding
litigation, increased competition, the size, timing and structure of significant
licenses,  the  timing  of  revenue  recognition  under its  time-based  license
agreements, the timing of new or enhanced product announcements,  introductions,
or delays in the  introductions,  of new or enhanced  versions of the  Company's
products, changes in pricing policies by the Company or its competitors,  market
acceptance  of  new  and  enhanced  versions  of  the  Company's  products,  the
cancellation   of   time-based   licenses   or   maintenance   agreements,   the
unavailability  of technology of third parties which is  incorporated in certain
of the products of the Company, the mix of direct and indirect sales, changes in
operating  expenses,  changes  in  the  Company's  strategy,  seasonal  factors,
personnel changes, foreign currency exchange rates and general economic factors.
Due to the foregoing  factors,  and  particularly  the  variability of the size,
timing and structure of significant  licenses,  quarterly  revenue and operating
results are difficult to forecast. In particular,  Avant! has adopted a flexible
pricing strategy  pursuant to which Avant!  offers both perpetual and time-based
software licenses to customers, depending on customer requirements and financial
constraints.  Because each time-based license may have a different structure and
could be subject to cancellation,  future revenue is unpredictable. In addition,
Meta's  quarterly  operating  results have in the past fluctuated as a result of
seasonality of customer buying patterns,  with revenues for the first quarter of
a year often lower than those for the last quarter of the preceding  year, and a
significant  portion of revenue in a quarter  typically  is received in the last
few weeks or days of that quarter.  The Company's  expense levels are based,  in
part, on expectations as to future revenue levels.  Accordingly,  net income, if
any, may be disproportionately affected by a reduction in revenue because only a
small  portion of the Company's  expenses  fluctuate  with  revenue.  If revenue
levels are below  expectations,  the Company's  business,  operating results and
financial  condition  are  likely  to be  materially  adversely  affected.  Such
shortfalls in the Company's revenue or operating results from levels expected by
public  market  analysts and investors  could have an immediate and  significant
material   adverse  effect  on  the  market  price  of  Avant!'s  Common  Stock.
Additionally,  the Company may not learn of such revenue  shortfalls or earnings
shortfalls  or  other  failures  to meet  market  expectations  for  results  of
operations  until late in a fiscal  quarter,  which could result in an even more
immediate and material  adverse  effect on the trading price of Avant!'s  Common
Stock.  In such  event,  the market  price of  Avant!'s  Common  Stock  would be
materially adversely affected. Due to the foregoing, Avant! believes that period
to  period  comparisons  of  its  results  of  operations  are  not  necessarily
meaningful and should not be relied upon as  indications of future  performance.
See "Selected Consolidated Financial Data."

Potential Volatility of Stock Price

         The  market  price of  Avant!'s  Common  Stock is  likely  to be highly
volatile  and may be  significantly  affected  by many  factors,  including  the
outcome of outstanding  litigation,  actual or anticipated  fluctuations  in the
Company's operating results,  announcements of technological innovations and new
products by competitors,  new contractual  relationships with strategic partners
by the  Company or its  competitors,  proposed  acquisitions  by the  Company or
competitors  and  financial  results  that fail to meet  public  market  analyst
expectations of performance. In addition, the U.S. equity markets have from time
to  time  experienced  significant  price  and  volume  fluctuations  that  have
particularly  affected  the market  prices for the common  stocks of  technology
companies.  These broad market fluctuations may materially  adversely affect the
market price of Avant!'s Common Stock in future periods.
See "Market Price of Avant! Common Stock; Dividends."


Cost of Integration; Transaction Expenses

         Transaction  costs  relating  to the  Acqusitions  and the  anticipated
combination  of certain  operations of Avant!,  Anagram,  Meta and FrontLine are
expected to result in one-time  charges to the Company's  earnings.  Although it
will not be feasible to determine  the actual  amount of these charges until the
operational  and  transition  plans  are  completed,  the  management  of Avant!
believes that the aggregate  charge will be  approximately  $8.9 million  before
taxes,  although  such  amount  may be  increased  by  unanticipated  additional
expenses incurred in connection with the Acquisitions.  This aggregate charge is
expected to include the estimated  costs  associated  with  financial  advisory,
accounting   and  legal  fees,   printing   expenses,   filing  fees  and  other
merger-related costs. While the

                                       7
<PAGE>

exact  timing  of these  expenses  cannot be  determined  at this  time,  Avant!
incurred  $920,000 of such costs in the quarter ended September 30, 1996 and the
management  of Avant!  anticipates  the  remaining  charge to  earnings  will be
recorded in the quarter  ending  December 31,  1996.  The effects of these costs
have not been  reflected  in the  unaudited  condensed  combined  statements  of
income,  except to the extent such costs were  actually  incurred in the quarter
ended September 30, 1996.


Potential Dilutive Effect to Stockholders

         Although Avant! believes that beneficial synergies will result from the
Acquisitions,  there  can  be no  assurance  that  the  combining  of  Avant!'s,
Anagram's,  Meta's and FrontLine's businesses,  even if achieved in an efficient
and  effective  manner,  will  result in  combined  results  of  operations  and
financial  condition  superior  to that which  would have been  achieved by each
company  independently,  or as to the period of time  required  to achieve  such
result. The issuance of Avant!  Common Stock in connection with the Acquisitions
is likely to have a dilutive effect on Avant!'s  earnings per share and there is
no  assurance  that Avant!  stockholders  would not achieve  greater  returns on
investment were Avant! to remain an independent company.


Shares Eligible for Public Sale

         Sales of  substantial  amounts  of Avant!  Common  Stock in the  public
market after the  consummation of the  Acqusitions  could  materially  adversely
affect  prevailing  market prices of Avant!'s Common Stock. The shares of Avant!
Common Stock issued in the  Acquisitions  are eligible for immediate sale in the
public  market,   subject  to  certain  limitations  under  the  Securities  Act
applicable  to  affiliates  of the Company and certain  agreements to be entered
into by certain affiliates of the acquired companies which prohibit such persons
from  disposing  of any  Avant!  Common  Stock  during  the  period  immediately
following the respective closing of the transactions.


Product Concentration

         The Company  expects  that revenue  from the  licensing  and support of
Aquarius,  the Company's place and route software product family,  Hercules, the
Company's  design  verification  software  product,  and  ADM  and  HSPICE,  the
Company's circuit simulation and analysis products,  respectively,  will account
for a  substantial  percentage  of the  Company's  revenues for the  foreseeable
future.  As a result,  the Company's  business,  operating results and financial
condition are  significantly  dependent  upon  continued  market  acceptance and
purchases of Aquarius,  Hercules, ADM and HSPICE. A decline in demand for any of
these products as a result of competition, technological change or other factors
would have a material  adverse  effect on the  business,  operating  results and
financial  condition of the Company.  There can be no assurance  that  Aquarius,
Hercules,  ADM or HSPICE will achieve continued market  acceptance,  or that the
Company will be  successful  in marketing  such  products or any new or enhanced
products.  Failure to develop or acquire additional products, or to successfully
market such products on a profitable basis, could have a material adverse effect
on the Company's business, operating results and financial condition.


Risks Associated with International Licensing

     International  revenue  accounted  for  approximately  33%  and  32% of the
Company's supplemental consolidated revenue in 1994 and 1995, respectively.  The
Company expects that international  license and service revenue will continue to
account for a significant portion of the Company's total revenue.  The Company's
international  revenue  involves  a number of  risks,  including  the  impact of
possible  recessionary  environments  in  economies  outside  the  U.S.,  longer
receivables  collection  periods and greater  difficulty in accounts  receivable
collection,  difficulties in staffing and managing foreign operations, political
and economic instability, unexpected changes in regulatory requirements, reduced
protection of  intellectual  property  rights in some  countries and tariffs and
other trade barriers.  Currency exchange  fluctuations in countries in which the
Company  licenses  its  products  could  also  materially  adversely  affect the
Company's  business,  operating results and financial  condition by resulting in
pricing  that is not  competitive  with  products  priced  in local  currencies.
Furthermore, there can b e no assurance

                                       8

<PAGE>

that in the future the Company  will be able to  continue to price its  products
and  services  internationally  in U.S.  dollars  because of changing  sovereign
restrictions  on importation  and  exportation of foreign  currencies as well as
other practical  considerations.  In addition,  the laws of certain countries do
not protect the Company's products and intellectual  property rights to the same
extent as do the laws of the U.S.  Accordingly,  there can be no assurance  that
these factors will not have a material  adverse  effect on the Company's  future
international  sales and,  consequently,  on the Company's  business,  operating
results and financial condition. In addition, there can be no assurance that the
Company will be able to sustain or increase  revenue derived from  international
licensing  and service or that the  foregoing  factors  will not have a material
adverse  effect  on the  Company's  future  international  license  and  service
revenue,  and,  consequently,  on the Company's business,  operating results and
financial condition.


Dependence Upon Distributors and Manufacturer's Representatives

         The Company relies on distributors and  manufacturer's  representatives
("Third  Party  Sellers")  for  licensing  and support of its products in China,
Japan,   Korea,   Singapore  and  Taiwan.  A  substantial  portion  of  Avant!'s
international license and service revenue results from a limited number of these
Third Party Sellers.  During 1994 and 1995 revenue from three  distributors  and
two manufacturer's  representatives  accounted for an aggregate of approximately
11%  of  Avant!'s  total  supplemental  consolidated  revenue.  There  can be no
assurance that Avant!'s current Third Party Sellers will choose to or be able to
market or service and support the Company's products effectively,  that economic
conditions  or industry  demand will not  materially  adversely  affect these or
other Third Party  Sellers or that these  Third  Party  Sellers  will not devote
greater  resources  to  marketing  and  supporting  products  of  the  Company's
competitors.  In  particular,  the Company  has opened a sales  office in Tokyo,
Japan,   which  may  affect  its   relationship   with  a  distributor  and  the
distributor's   performance  as  a  distributor   of  the  Company's   products.
Additionally,  because  the  Company's  products  are  used  by  highly  skilled
professional  engineers, a Third Party Seller must possess sufficient technical,
marketing  and sales  resources in order to be  effective  and must devote these
resources to a lengthy sales cycle,  customer  training and product  service and
support.  Only a limited number of Third Party Sellers  possess such  resources.
Accordingly,  the loss of or a decision by Avant!  not to renew agreements with,
or a significant  reduction in revenue from, one of Avant!'s Third Party Sellers
or any other Third Party  Sellers on which the  Company's  revenues  may, in the
future, become dependent,  could have a material adverse effect on the Company's
business, operating results and financial condition.

New Products and Rapid Technological Change

         The ICDA industry is  characterized  by extremely  rapid  technological
change,  frequent new product introductions and enhancements,  evolving industry
standards and rapidly  changing  customer  requirements.  The  Company's  future
business, operating results and financial condition will depend in part upon its
ability  to enhance  its  current  products  and to develop  and  introduce  new
products  on a  timely  and  cost-effective  basis  that  will  keep  pace  with
technological developments and evolving industry standards and methodologies, as
well as address the increasingly sophisticated needs of the Company's customers.
New  technologies  developed  by the  Company or its  competitors  could  render
existing products  obsolete.  The Company's success will depend upon its ability
to enhance  existing  products  and to  introduce  new  products on a timely and
cost-effective basis that meet changing customer  requirements.  There can be no
assurance  that the Company will be  successful  in  developing  new products or
enhancing  existing  products or that such new or enhanced products will receive
market  acceptance.  On  occasion,  the  Company has  experienced  delays in the
scheduled  introductions  of new and  enhanced  products,  and  there  can be no
assurance  that it will be able to  introduce  products on a timely basis in the
future. Delays in the scheduled  availability of products,  for technological or
other reasons, or a lack of market acceptance of such products, or the Company's
failure to accurately  anticipate customer demand, would have a material adverse
effect on its business, operating results and financial condition.


Dependence Upon Semiconductor and Electronics  Industries;  General Economic and
Market Conditions

         Avant! is dependent upon the  semiconductor  and, more  generally,  the
electronics  industries.  Each of these  industries  is  characterized  by rapid
technological  change, short product life cycles,  fluctuations in manufacturing

                                       9
<PAGE>

capacity and pricing and gross margin  pressures.  Segments of these  industries
have from time to time experienced  significant economic downturns characterized
by decreased  product  demand,  production  over-capacity,  price erosion,  work
slowdowns  and  layoffs.   Over  the  past  few  years,  these  industries  have
experienced an extended period of significant  economic growth,  although during
1996 certain  sectors of the  semiconductor  industry  have  experienced  slower
growth than in 1995.  There can be no assurance  that  economic  growth in these
industries  will continue,  and if it does not, any downturn could be especially
severe  on the  Company.  During  such  downturns,  the  number of new IC design
projects often decreases.  Because acquisitions of new licenses from the Company
are largely dependent upon the commencement of new design projects, any slowdown
in these  industries  could  have a  material  adverse  effect on the  Company's
business,  operating results and financial  condition.  The Company's  business,
operating results and financial  condition may in the future reflect substantial
fluctuations  from period to period as a  consequence  of  patterns  and general
economic conditions in either the semiconductor or electronics industry.


Limitations on Protection of Intellectual Property and Proprietary Rights

         The Company relies on a combination of patents, trade secret, copyright
and  trademark  laws,  as  well  as  contractual  commitments,  to  protect  its
proprietary rights in its software  products.  The Company generally enters into
confidentiality  or license  agreements  with its  employees,  distributors  and
customers, and limits access to and distribution of its software,  documentation
and other proprietary  information.  Despite these precautions,  there can be no
assurance  that a third  party  will not copy or  otherwise  obtain  and use the
Company's  products or  technology  without  authorization,  or develop  similar
technology independently. In particular, the Company has on occasion distributed
its products pursuant to "shrink wrap" licenses.  There can be no assurance that
such licenses are enforceable. In addition, effective copyright and trade secret
protection  may be  unavailable  or limited in certain  foreign  countries.  The
Company  expects  that  software  companies  will  increasingly  be  subject  to
infringement claims as the number of products and competitors in the industry in
which  Avant!  currently  competes  grows and the  functionality  of products in
different industry segments overlaps. In particular, Avant!'s current litigation
with Cadence  involves  such  infringement  claims.  Responding  to such claims,
regardless of merit, could be time-consuming, result in costly litigation, cause
product  shipment  delays or  require  the  Company  to enter  into  royalty  or
licensing agreements. Such royalty or licensing agreements, if required, may not
be available on terms  acceptable  to the Company or at all,  which could have a
material  adverse  effect upon the  Company's  business,  operating  results and
financial condition. There can be no assurance that infringement claims will not
be  asserted  against the Company in the future or that any such claims will not
require  the  Company to enter  into  royalty  arrangements  or result in costly
litigation,  which could  materially  adversely  affect the Company's  business,
operating results and financial condition. See "--Litigation Risk."


Risk of Product Defects

         Software  products  as complex  as those  offered  by the  Company  may
contain  defects or failures when  introduced or when new versions are released.
Avant!  has in the past discovered  software  defects in certain of its products
and may experience delays or lost revenue to correct such defects in the future.
There can be no assurance that, despite testing by the Company,  errors will not
be found in new products or releases after commencement of commercial shipments,
resulting in loss of market share or failure to achieve market  acceptance.  Any
such  occurrence  could  have a  material  adverse  effect  upon  the  Company's
business, operating results and financial condition.


Dependence Upon Relationship with Synopsys

         Avant!  currently has a cooperative  technical and marketing  agreement
with Synopsys, Inc. ("Synopsys") that expires by its terms in March 1997, and is
automatically  renewed for one year unless either party gives notice  otherwise.
The agreement  provides that Synopsys will share certain  technical  information
with Avant!  concerning Synopsys' high level design automation  products,  which
information  has  assisted  Avant!  in  the  development  and  marketing  of its
products.  Synopsys has no obligation to continue to provide similar information
in the future,  and if 

                                       10
<PAGE>

Synopsys  were to stop  sharing  technical  information  with  Avant!,  to favor
competitors of Avant! or to develop software  products that are competitive with
those of Avant!,  Avant!'s business,  operating results and financial  condition
could be materially adversely affected.  While Avant!  believes its relationship
with Synopsys is good,  there can be no assurance that the Acquisitons  will not
have an adverse effect on the existing relationship with Synopsys.


Concentration of Stock Ownership; Change of Control Provisions

         Based on the stock  ownership  of the Company as of November  30, 1996,
the  directors and principal  stockholders  of the Company and their  affiliates
will  beneficially  own a significant  amount of the outstanding  Avant!  Common
Stock.  As a result,  these  stockholders  will be able to exercise  significant
influence  over  all  matters  requiring  stockholder  approval,  including  the
election of directors and approval of significant corporate  transactions.  Such
concentration  of  ownership  may have the effect of  delaying or  preventing  a
change in control of Avant!. In addition,  the Company's Board of Directors will
have the  authority  to issue up to  5,000,000  shares of  Preferred  Stock,  to
determine the powers, preferences and rights and the qualifications, limitations
or  restrictions  granted to or imposed  upon any  unissued  series of Preferred
Stock  and to  fix  the  number  of  shares  constituting  any  series  and  the
designation of such series,  without any further vote or action by the Company's
stockholders.  The  Preferred  Stock could be issued with  voting,  liquidation,
dividend  and other  rights  superior  to the  rights of the Common  Stock.  The
issuance of Preferred Stock under certain circumstances could have the effect of
delaying or preventing a change in control of the Company.

                                   THE COMPANY

         Avant!  develops,   markets  and  supports  integrated  circuit  design
automation  ("ICDA")  software for the physical  design,  layout,  verification,
simulation and analysis of high-density,  high-performance  integrated  circuits
("ICs").  Avant!'s  objective is to establish a significant market position as a
supplier  of physical  design  software  for the ICDA  market.  To achieve  this
objective,  Avant!  has  adopted  its  mission,  which is to provide  innovative
technology,  products,  and business  models that enable  customers to solve the
toughest  problems in deep submicron IC design,  improve their  productivity and
achieve a high return on their  investment.  To effect its mission,  Avant!  has
adopted the  strategies of  maintaining  focus on  technological  innovation and
creating strategic relationships with customers. The principal executive offices
of Avant! are located at 1208 East Arques Avenue,  Sunnyvale,  California 94086.
Avant!'s telephone number is (408)738-8881.


                               Recent Developments

         On August 2, 1996 Avant!  announced  Version 2.0 of its deep  submicron
product families which include the Aquarius family of place and route tools; the
Planet family of  floorplanning  tools;  the Star family of simulation,  timing,
analysis and RC extraction tools; the Solar family of synthesis-oriented  layout
refinement  tools; and the Hercules family of physical  verification  tools. The
Aquarius   family  consists  of  Aquarius-BV,   which   supersedes   ArcCell-BV,
Aquarius-XO,  which supersedes  ArcCell-XO,  and  Aquarius-GA,  which supersedes
ArcGate.  The Hercules  product family  supersedes  Avant!'s  VeriCheck  product
family.  The Star family is a new product that analyzes the  performance of deep
submicron ICs, including the most complex, high-performance microprocessors. The
Star product family is a full-chip extraction, delay analysis and data reduction
tool for IC designers to use during physical design.  Star is tightly integrated
with Avant!'s hierarchical layout and verification tools, Aquarius and Hercules,
to provide efficient,  accurate and predictable IC performance. The Solar family
is a new product that optimizes the performance and area of ICs to meet new deep
submicron  "golden  file"  needs.  Solar is  tightly  integrated  with  Avant!'s
Aquarius family of place and route tools.

         In  September  1996,  Avant!  acquired  Anagram,  Inc.  ("Anagram"),  a
developer of simulation  and analysis ICDA  software for  high-performance  deep
submicron ICs (the "Anagram Acquisition"). Anagram's objective is to establish a
significant market position as a supplier of easy-to-use,  high-capacity circuit
simulation  and  high-accuracy  timing  analysis  software.  Anagram's  flagship
product, ADM, is a high-capacity circuit simulator for deep submicron processor,
graphics, memory,  communications,  and mixed-signal IC designs. ADM is designed
to be  compatible  with the most  commonly  used  ICDA  tools  and to be  easily
integrated  in the  customer's  existing  design  environment  and  methodology.
Anagram's  products help increase IC performance  and  reliability  and increase
designer  productivity by enabling  designers to characterize  large blocks;  to
accurately  simulate  mixed-signal,  dynamic  logic and  memory  circuits  where
performance,  signal  integrity and power analyses are  essential;  and to reuse
high-performance  intellectual  property  without  changing the design  process.
Anagram's ADM circuit simulation and analysis tool is currently being integrated
into the Star  product  family.  Upon the  closing of the  Anagram  Acquisition,
Anagram became a wholly owned subsidiary of Avant! and all of the  fully-diluted
shares of  Anagram  capital  stock  and  stock  options  were  exchanged  for an
aggregate of approximately  2,414,000  shares of Avant!  Common Stock and Avant!
stock  options.  The  Anagram  Acquisition  was  accounted  for as a pooling  of
interests. See "Risk Factors--Uncertainty  Relating to Integration of Operations
and Product Lines;  Management of Growth,"  "--Cost of Integration;  Transaction
Expenses" and "Avant! Business--Recent Developments."

         In October  1996,  Avant!  acquired  Meta-Software,  Inc.  ("Meta"),  a
developer  of library  generation  software  products  for use in IC design (the
"Meta Acquisition"). Meta's products include HSPICE, an industry leading circuit
simulator in use at over 1,500 commercial  customer sites worldwide,  and MASTER
Toolbox,  an automated  cell  characterization  and library  generation  program
introduced in late 1994.  Meta's  products  assist IC designers in  ascertaining
whether  semiconductor  devices based on their designs will meet  functional and
performance  specifications  when  fabricated in silicon.  Avant!  believes that
Meta's  products can be used to reduce time to market,  enhance IC  performance,
lower design costs and validate  designs  across  multiple  foundries.  Upon the
closing of the Meta Acquisition, Meta became a wholly owned subsidiary of Avant!
and all of the fully-diluted shares of Meta capital stock and stock options were
exchanged for an aggregate of approximately  5,080,000  shares of Avant!  Common
Stock and Avant!  stock  options.  The Meta  Acquisition  was accounted for as a
pooling of interests. See "Risk Factors--Uncertainty Relating to

         In November 1996, Avant!  acquired  FrontLine Design  Automation,  Inc.
("FrontLine"),  a  developer  of Verilog  simulation  solutions  to improve  the
productivity  of  hardware  logic   designers  (the  "FrontLine   Acquisition").
FrontLine  has  developed a unified HDL  simulation  architechture  with Verilog
compatibility  that offers (i) multiple  levels of  abstraction;  (ii)  multiple
simulation  of  algorithms;  and  (iii)  multiple  HDL  compilation  techniques.
FrontLine's  products  run on UNIX  and  Windows,  and  provide  a  multi-engine
architecture  with  high-performance  cycle  based and event  driven  simulation
support.  The tools are used by  designers  of complex  integrated  circuits and
field  programmable  gate arrays to verify the  functionality of their chips and
systems prior to  manufacturing.  Upon the closing of theFrontLine  Acquisition,
FrontLine   became  a  wholly  owned   subsidiary  of  Avant!  and  all  of  the
fully-diluted  shares  of  FrrontLine  capital  stock  and  stock  options  were
exchanged for an aggregate of 2,222,222 shares of Avant! Common Stock and Avant!
stock  options.  The  FrontLine  Acquisition  was  accounted for as a pooling of
interests. See "Risk Factors--Uncertainty  Relating to Integration of Operations
and Product Lines;  Management of Growth,"  "--Cost of Integration;  Transaction
Expenses" and "Avant! Business--Recent Developments."

                              PLAN OF DISTRIBUTION                              

         All  or  a  portion  of  the  Shares  offered  hereby  by  the  Selling
Stockholders  may be delivered  and/or sold from time to time in transactions in
the  over-the-counter  market,  on the  Nasdaq  National  Market,  in  privately
negotiated  transactions,  or by a combination of such methods of sale, at fixed
prices that may be changed,  at market prices prevailing at the time of sale, at
prices related to such prevailing market prices or at negotiated  prices.  After
the  effectiveness of the  Registration  Statement of which this Prospectus is a
part,  the Selling  Stockholders  may make short sales of the  Company's  Common
Stock and may use the Shares to cover the resulting short positions. The Selling
Stockholders  may effect such  transactions  by selling the Shares to or through
broker-dealers and such  broker-dealers may receive  compensation in the form of
discounts,  concessions  or  commissions  from the Selling  Stockholders  or the
purchasers  of the  Shares for whom such  broker-dealers  may act as agent or to
whom  they  sell  as  principal  or both  (which  compensation  to a  particular
broker-dealer  might  be  in  excess  of  customary  commissions).  The  Selling
Stockholders  and any  broker-dealers  that  participate in the distribution may
under certain circumstances be deemed to be "underwriters" within the meaning of
the Securities Act, and any commissions  received by such broker-dealers and any
profits  realized  on the  resale  of Shares  may be  deemed to be  underwriting
discounts and commissions under the Securities Act. The Selling Stockholders may
agree to indemnify such broker-dealers  against certain  liabilities,  including
liabilities  under the  Securities  Act. In addition,  the Company has agreed to
indemnify the Selling  Stockholders  with respect to the Shares  offered  hereby
against certain liabilities,  including certain liabilities under the Securities
Act, or, if such indemnity is unavailable, to contribute toward amounts required
to be paid in respect of such liabilities.

         Any  broker-dealer  participating  in such  transactions  as agent  may
receive commissions from the Selling  Stockholders (and, if it acts as agent for
the purchase of such Shares, from such purchaser). Broker-dealers may agree with
the Selling  Stockholders  to sell a specified  number of Shares at a stipulated
price per share,  and,  to the extent  such a  broker-dealer  is unable to do so
acting as agent for the  Selling  Stockholders,  to purchase  as  principal  any
unsold  Shares.  Broker-dealers  who acquire  Shares as principal may thereafter
resell such Shares from time to time in transactions  (which may involve crosses
and  block  transactions  and  which  may  involve  sales to and  through  other
broker-dealers,  including  transactions of the nature  described  above) in the
over-the-counter  market, on the Nasdaq National Market, in privately negotiated
transactions,  or by a combination of such methods of sale, at fixed prices that
may be  changed,  at market  prices  prevailing  at the time of sale,  at prices
related  to such  prevailing  market  prices  or at  negotiated  prices,  and in
connection  with such resales may pay to or receive from the  purchasers of such
Shares commissions computed as described above.

         The Selling  Stockholders  will be subject to applicable  provisions of
the Exchange Act, and the rules and regulations thereunder,  including,  without
limitation, Rules 10b-6 and 10b-7, which provisions may limit the timing of bids
for and  purchases  of  shares  of the  Company's  Common  Stock by the  Selling
Stockholders.

         The Selling  Stockholders  will pay all  commissions and other expenses
associated  with the sale of securities by them.  The Shares  offered hereby are
being  registered  pursuant to contractual  obligations of the Company,  and the
Company has agreed to bear certain  expenses in connection with the registration
and sale of the Shares being  offered by the Selling  Stockholders.  The Company
has not made any  underwriting  arrangements  with respect to the sale of Shares
offered hereby.


                                  LEGAL MATTERS

         The legality of the  securities  offered hereby will be passed upon for
the Company by Gunderson  Dettmer Stough Villeneuve  Franklin & Hachigian,  LLP,
Menlo Park, California.

                     INFORMATION NOT REQUIRED IN PROSPECTUS


Item 14.  Other Expenses of Issuance and Distribution.

         The fees and expenses  incurred by the Company in  connection  with the
offering are payable by the Company and,  other than filing fees,  are estimated
as follows:

          Securities and Exchange Commission Registration Fee......    $ 16,208
          Legal Fees and Expenses..................................      75,000
          Accounting Fees and Expenses.............................     130,000
          Miscellaneous............................................      53,792
                                                                       --------
               Total...............................................     275,000
                                                                       ========


Item 15.   Indemnification of Directors and Officers.

         Section 145 of the Delaware General Corporation law ("DGCL") empowers a
Delaware  corporation  to indemnify any persons who are, or are threatened to be
made,  parties to any  threatened,  pending or completed  legal action,  suit or
proceedings,  whether civil,  criminal,  administrative or investigative  (other
than action by or in the right of such corporation),  by reason of the fact that
such person was an officer or director of such corporation, or is or was serving
at the request of such corporation as a director,  officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys' fees),  judgments,  fines and amounts paid in settlement actually and
reasonably  incurred  by such person in  connection  with such  action,  suit or
proceeding,  provided that such officer or director acted in good faith and in a
manner he reasonably  believed to be in or not opposed to the corporation's best
interests, and, for criminal proceedings, had no reasonable cause to believe his
conduct was illegal. A Delaware corporation may indemnify officers and directors
in an action by or in the right of the  corporation  under the same  conditions,
except that no  indemnification  is permitted  without judicial  approval if the
officer  or  director  is  adjudged  to be  liable  to  the  corporation  in the
performance  of his duty.  Where an officer or  director  is  successful  on the
merits or  otherwise  in the  defense  of any  action  referred  to  above,  the
corporation  must  indemnify  him against  the  expenses  which such  officer or
director actually and reasonably incurred.

         In accordance  with the DGCL,  Avant!'s  Certificate  of  Incorporation
("Certificate")  contains a provision  to limit the  personal  liability  of the
directors  of the  Registrant  for  violations  of their  fiduciary  duty.  This
provision  eliminates  each  director's  liability  to  the  Registrant  or  its
stockholders  for monetary  damages  except (i) for any breach of the director's
duty  of  loyalty  to the  Registrant  or its  stockholders,  (ii)  for  acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL providing for liability of
directors  for  unlawful  payment of dividends  or unlawful  stock  purchases or
redemptions,  or (iv) for any  transaction  from  which a  director  derived  an
improper  personal  benefit.  The effect of this  provision is to eliminate  the
personal  liability of directors  for monetary  damages for actions  involving a
breach of their  fiduciary  duty of care,  including any such actions  involving
gross negligence.

         Article  IX of  Avant!'s  Certificate  and  Article  VII,  Section 6 of
Avant!'s Bylaws provide for indemnification of the officers and directors of the
Registrant to the fullest extent permitted by applicable law.

         The Registrant has entered into  indemnification  agreements  with each
director and executive officer which provide  indemnification  to such directors
and executive  officers under certain  circumstances for acts or omissions which
may not be covered by directors' and officers' liability insurance.

Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

         The  undersigned  Registrant  hereby  undertakes  that, for purposes of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act (and, where  applicable,  each filing of an employee benefit plan's
annual  report   pursuant  to  Section  15(d)  of  the  Exchange  Act)  that  is
incorporated by reference in the Registration  Statement shall be deemed to be a
new registration  statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         For purposes of determining any liability under the Securities Act, the
information  omitted  from  the  form  of  prospectus  filed  as  part  of  this
Registration  Statement  in reliance  upon Rule 430A and  contained in a form of
prospectus  filed by the Registrant  pursuant to Rule 424(b)(1) or (4) or 497(h)
under  the  Securities  Act  shall  be  deemed  to be part of this  Registration
Statement as of the time it was declared effective.

                          REGISTRATION RIGHTS AGREEMENT

                  THIS REGISTRATION  RIGHTS AGREEMENT is made as of the 27th day
of November,  1996, by and between Avant!  Corporation,  a Delaware  corporation
(the "Company"),  and Badruddin Agarwala,  on behalf of the shareholders and the
holders  of   warrants   listed  on   Schedule  A  hereto   (collectively,   the
"Shareholders"   and   individually,   a  "Shareholder")   of  FrontLine  Design
Automation, Inc., a California corporation ("FrontLine").

                                    RECITALS

                  WHEREAS,   the  Company  and  FrontLine  are  parties  to  the
Agreement and Plan of  Reorganization  dated October 9, 1996  (together with all
exhibits,  schedules,  supplements  and any  amendments  thereto,  the  "Plan of
Reorganization"),   pursuant  to  which  the  Company   shall  acquire  all  the
outstanding  shares of capital  stock of  FrontLine  in  exchange  for shares of
common stock (the "Common Stock") of the Company (the "Merger");

                  WHEREAS,  the  parties  to the  Plan  of  Reorganization  have
determined  that in  light  of  recent  federal  legislation  it is in the  best
interests of the parties  thereto to grant  certain  registration  rights to the
Shareholders as set forth herein; and

                  WHEREAS, all terms not otherwise defined herein shall have the
same meanings ascribed to them in the Plan of Reorganization;

                  NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

                  1.    Registration  Rights The Company covenants and agrees as
                        follows:

                  1.1   Definitions. For purposes of this Section 1:

                            (a) The term "Act" means the Securities Act of 1933,
as amended.

                            (b) The term "1934  Act"  shall mean the  Securities
Exchange Act of 1934, as amended.

                            (c)  The   terms   "register,"   "registered,"   and
"registration"  refer to a  registration  effected  by  preparing  and  filing a
registration  statement or similar  document in compliance with the Act, and the
declaration  or ordering of  effectiveness  of such  registration  statement  or
document.

                            (d) The  term  "Registrable  Securities"  means  the
Common Stock of the Company issued to the  Shareholders in the Merger and shares
of Common Stock of the Company  issuable upon exercise of outstanding  warrants,
and any Common Stock of the Company  issued as a dividend or other  distribution
with respect to such Common Stock.

<PAGE>

                            (e)  The  term   "Rule  144"  shall  mean  Rule  144
promulgated  under the Act, as amended,  or any similar  successor  rule thereto
that may be promulgated by the SEC.

                            (f) The term  "SEC"  shall mean the  Securities  and
Exchange Commission.

                  1.2   Registration.

                            (a) If by  December  16,  1996  the SEC (A)  takes a
position  in  a   definitive   pronouncement   (i.e.   a  no-action   letter  or
interpretative  release), that (i) a Nasdaq National Market company may not rely
on a fairness hearing  pursuant to Section 25142 of the California  Corporations
Code to avail itself of an exemption under Section  3(a)(10) of the Act, or (ii)
any securities  issued pursuant to such a fairness  hearing and in reliance upon
Section  3(a)(10) are deemed to be restricted  securities and therefore will not
be  freely  transferable,  or (B)  fails  to  take a  position  in a  definitive
pronouncement  with respect to the matters  described in clause (A), then Avant!
shall file on that date with the SEC a  registration  statement  covering all of
the  Registrable  Securities,  and  shall  use its  best  efforts  to have  such
registration  statement  declared  effective  within two days of the publication
(within the meaning of Accounting Series Release No. 135 as amended, of the SEC)
of financial  results covering at least one month of combined  operations of the
Company and FrontLine, approximately January 21, 1997.

                            (b)  Notwithstanding  the foregoing,  if the Company
shall furnish to the  Shareholders a certificate  signed by the Chief  Executive
Officer of the Company  stating that in the good faith  judgment of the Board of
Directors  of the  Company,  it  would be  detrimental  to the  Company  and its
stockholders  for such  registration  statement to be filed, and it is therefore
essential to defer the filing of such registration statement,  the Company shall
have the right to defer filing the registration statement referred to in Section
1.2(a) until December 26, 1996.

                            (c) In no event shall the Company's  insider trading
window be opened unless the registration  statement has been declared  effective
by the SEC.

                   1.3. Company Registration.  If (but without any obligation to
do  so)  the  Company  proposes  to  register  (including  for  this  purpose  a
registration   effected  by  the  Company  for   stockholders   other  than  the
Shareholder)  any of its stock or other  securities  under the Act in connection
with the  public  offering  of such  securities  solely for cash  (other  than a
registration  relating  solely to the sale of  securities to  participants  in a
Company  stock plan, a  registration  on any form which is not available for the
resale of the Registrable  Securities,  a registration  statement on Form S-4 or
any  successor  form,  or a  registration  in which the only Common  Stock being
registered is Common Stock issuable upon conversion of debt securities which are
also being  registered),  the Company  shall,  at such time,  promptly  give the
Shareholders  written notice of such  registration.  Upon the written request of
the Shareholders  given within ten (10) days after mailing of such notice by the
Company in accordance with Section 2.5, the Company shall cause to be registered
under  the  Act all of the  Registrable  Securities  that  the  Shareholder  has
requested to be registered. In connection with any registration pursuant to this
Section  1.3  which  involves  the   underwritten   offering  of  the  Company's
securities,   the  Company   shall  not  be  required  to  include  any  of  the
Shareholder's   securities   under  such   registration   statement  unless 

                                       2
<PAGE>


the  Shareholder  agrees to enter  into an  underwriting  agreement  in the form
agreed upon between the Company and the underwriters selected by it (or by other
persons entitled to select the underwriters),  and then only in such quantity as
the  underwriters  determine in their sole  discretion  will not  jeopardize the
success of the offering by the Company. Each Shareholder acknowledges and agrees
that at the  underwriters'  sole  discretion the  Registrable  Securities may be
excluded  entirely from such offering.  In addition,  if a registration is to be
effected pursuant to a request by another holder of Common Stock of the Company,
the Shareholder's right to participate in any such registration shall be subject
to the prior  consent  of such  holder  which  consent  may be  withheld  in the
holder's sole discretion.

                  1.4 Obligations of the Company.  Whenever  required under this
Section 1 to effect the registration of any Registrable Securities,  the Company
shall:

                            (a)  Prepare  and file with the SEC, a  registration
statement  with respect to such  Registrable  Securities and use best efforts to
cause such  registration  statement  to become  effective,  and,  subject to the
provisions  below,  use  best  efforts  to,  keep  such  registration  statement
effective  for a period  of two years or,  if  earlier,  until the  distribution
contemplated in the  registration  statement has been completed.  If at any time
after a  registration  statement  becomes  effective,  the  Company  advises the
Shareholders in writing that due to the existence of material  information  that
has not been disclosed to the public and included in the registration  statement
it is thus necessary to amend the registration statement (including by reporting
such information under the 1934 Act), the Shareholders shall suspend any further
sale of Registrable  Securities pursuant to the registration statement until the
registration  statement has been amended.  In such event,  the Company shall use
best  efforts  to  amend  the  registration  statement  as  soon  as  reasonably
practicable  and in no event  later  than the  earlier  of (i) 10 days after the
Company has advised  Shareholders  to suspend  sales (which 10 day period may be
extended, one time only, an additional 10 days (the "Additional  Suspension") if
the Board of Directors of the Company in its good faith judgment determines that
such disclosure  would be  substantially  detrimental to the Company;  provided,
however,  that the  Company  shall  only have the right to effect an  Additional
Suspension  not  more  than  twice  in any  twelve  month  period)  or (ii)  the
commencement  of any period in which  directors  and officers of the Company are
allowed to buy or sell  Common  Stock of the Company  pursuant to the  Company's
insider trading policy. The Company shall not impose a suspension on the sale of
Registrable  Securities by the Shareholders unless the Company's insider trading
window is closed.  When selling  Registrable  Securities,  a  Shareholder  shall
follow  the  procedures  set  forth  in  Section  1.9  and may  presume  that no
suspension  is in  effect  if a trade is made in the  manner  described  in that
section.

                            (b) Subject to subsection  1.4(a),  prepare and file
with the SEC such amendments and supplements to such registration  statement and
the prospectus  used in connection  with such  registration  statement as may be
necessary  to  comply  with  the  provisions  of the  Act  with  respect  to the
disposition of all securities covered by such registration statement.

                            (c)   Furnish   to   the   Shareholders   requesting
registration  such numbers of copies of a  prospectus,  including a  preliminary
prospectus,  in  conformity  with the  

                                       3

<PAGE>

requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

                            (d) Use best  efforts to  register  and  qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such  jurisdictions  as shall be  reasonably  requested  by the
Shareholders holding a majority of the Registrable Securities; provided that the
Company shall not be required in connection  therewith or as a condition thereto
to qualify to do business or to file a general  consent to service of process in
any such  states or  jurisdictions,  unless the  Company  is already  subject to
service in such jurisdiction and except as may be required by the Act.

                  1.5  Information from Shareholders.  It shall  be a  condition
precedent to the  obligations of the Company to take any action pursuant to this
Section 1 with respect to the Registrable  Securities of a Shareholder that such
Shareholder  shall furnish to the Company such information  regarding himself or
herself, the Registrable  Securities held by him or her, and the intended method
of  disposition  of such  securities  as shall be  reasonably  requested  by the
Company and required to effect the registration of the Registrable Securities.

                  1.6  Expenses of Registration.    All    expenses    of    the
Shareholders,   except   commissions,   including   (without   limitation)   all
registration, filing and qualification fees, printers' and accounting fees, fees
and  disbursements  of counsel  for the Company  shall be borne by the  Company;
provided,   however,  that  the  Company  shall  not  be  required  to  pay  any
professional  fees of the Shareholders  other than the fees of a special counsel
to the Shareholders (not to exceed $15,000).

                  1.7 No Assignment of  Registration  Rights.  The  registration
rights provided  hereunder are not  assignable,  except to a transferee upon the
death  of a  Shareholder,  a  personal  legal  representative  in the  event  of
incapacity of the Shareholder or otherwise by operation of law.  Notwithstanding
the foregoing,  the registration  rights provided hereunder may be assigned by a
Shareholder to a transferee or assignee of such securities who shall,  upon such
transfer or assignment, be deemed a "Shareholder" under this Agreement; provided
that the Company is,  within a  reasonable  period of time after such  transfer,
furnished  with  written  notice of the name and address of such  transferee  or
assignee and the Registrable Securities with respect to such registration rights
are being assigned;  provided,  further, that such assignment shall be effective
only if immediately  following such transfer (A) the further disposition of such
securities by the  transferee or assignee is restricted  under the Act, (B) that
such  transferee  or  assignee  is a  member  of  the  immediate  family  of the
Shareholder or a trust for the benefit of any Shareholder  that is an individual
(or for the benefit of an immediate family member of such Shareholder),  and (C)
that such  transfer  or  assignment  consists of at least  25,000  shares of the
Registrable  Securities  or all of  the  Registrable  Securities  held  by  such
Shareholder.

                  1.8 Indemnification.  In the event any Registrable  Securities
are included in a registration statement under this Section 1:

                            (a) The Company  will  indemnify  and hold  harmless
each  Shareholder and any  controlling  person of such  Shareholder  against any
losses,  claims,  damages,  or  liabilities 

                                       4
<PAGE>

(joint or several) to which he may become  subject  under the Act, the 1934 Act,
or other  federal or State laws,  insofar as such losses,  claims,  damages,  or
liabilities  (or actions in respect  thereof) arise out of or are based upon any
of  the  following   statements,   omissions  or  violations   (collectively   a
"Violation"): (i) any untrue statement or alleged untrue statement of a material
fact  contained  in  such  registration  statement,  including  any  preliminary
prospectus  or  final  prospectus   contained   therein  or  any  amendments  or
supplements  thereto,  (ii) any omission or alleged  omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not  misleading,  or (iii) any  violation  or alleged  violation  by the
Company of the Act, the 1934 Act, or any rule or  regulation  promulgated  under
the Act, or the 1934 Act or other federal or State law; and the Company will pay
to Shareholder,  as incurred, any legal or other expenses reasonably incurred by
him in connection with investigating or defending any such loss, claim,  damage,
liability, or action; provided,  however, that the indemnity agreement contained
in this  subsection 1.8 (a) shall not apply to amounts paid in settlement of any
such loss, claim,  damage,  liability,  or action if such settlement is effected
without the consent of the  Company,  which  consent  shall not be  unreasonably
withheld,  nor shall the  Company  be liable in any such case for any such loss,
claim,  damage,  liability,  or action to the extent that it arises out of or is
based upon a Violation  which  occurs in reliance  upon and in  conformity  with
information  furnished expressly for use in connection with such registration by
Shareholder.  In  addition,  the  Company  shall  not be liable  for any  untrue
statement or omission in any  prospectus  if a supplement  or amendment  thereto
correcting such untrue statement or omission was delivered to Shareholder  prior
to the pertinent sale or sales by Shareholder.

                            (b)  Each   Shareholder   will  indemnify  and  hold
harmless the Company, each of its directors, each of its officers who has signed
the registration statement, each person, if any, who controls the Company within
the  meaning  of the Act,  any  other  Shareholder  selling  securities  in such
registration  statement  and any  controlling  person  of any such  Shareholder,
against any losses, claims,  damages, or liabilities (joint or several) to which
any of the foregoing persons may become subject,  under the Act, or the 1934 Act
or other  federal or state law,  insofar as such  losses,  claims,  damages,  or
liabilities  (or actions in respect  thereto) arise out of or are based upon any
Violation,  in each  case to the  extent  (and  only to the  extent)  that  such
Violation  occurs in reliance  upon and in conformity  with written  information
furnished by Shareholder expressly for use in connection with such registration;
and Shareholder  will pay, as incurred,  any legal or other expenses  reasonably
incurred by any person  intended to be indemnified  pursuant to this  subsection
1.8(b),  in connection  with  investigating  or defending any such loss,  claim,
damage,  liability, or action;  provided,  however, that the indemnity agreement
contained  in  this  subsection  1.8(b)  shall  not  apply  to  amounts  paid in
settlement  of any  such  loss,  claim,  damage,  liability  or  action  if such
settlement is effected  without the consent of Shareholder,  which consent shall
not be unreasonably  withheld;  provided,  that, in no event shall any indemnity
under  this  subsection  1.8(b)  exceed  the gross  proceeds  from the  offering
received by Shareholder.

                            (c) Promptly after receipt by an  indemnified  party
under this Section 1.8 of notice of the  commencement  of any action  (including
any governmental  action),  such  indemnified  party will, if a claim in respect
thereof is to be made  against any  indemnifying  party under this  Section 1.8,
deliver to the indemnifying  party a written notice of the commencement  thereof
and the  indemnifying  party shall have the right to participate in, and, to 

                                       5

<PAGE>

the  extent  the  indemnifying   party  so  desires,   jointly  with  any  other
indemnifying party similarly noticed, to assume the defense thereof with counsel
mutually  satisfactory to the parties;  provided,  however,  that an indemnified
party  (together  with all other  indemnified  parties which may be  represented
without  conflict by one  counsel)  shall have the right to retain one  separate
counsel,  with the fees and expenses to be paid by the  indemnifying  party,  if
representation  of  such  indemnified  party  by  the  counsel  retained  by the
indemnifying  party would be inappropriate due to actual or potential  differing
interests between such indemnified party and any other party represented by such
counsel  in such  proceeding.  The  failure  to  deliver  written  notice to the
indemnifying  party within a  reasonable  time of the  commencement  of any such
action, if prejudicial to its ability to defend such action,  shall relieve such
indemnifying  party of any liability to the indemnified party under this Section
1.8, but the omission so to deliver  written  notice to the  indemnifying  party
will not relieve it of any liability that it may have to any  indemnified  party
otherwise than under this Section 1.8.

                            (d)  If the  indemnification  provided  for in  this
Section 1.8 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein,  then the indemnifying  party, in lieu of indemnifying such
indemnified  party hereunder,  shall contribute to the amount paid or payable by
such indemnified party as a result of such loss,  liability,  claim,  damage, or
expense in such  proportion as is  appropriate  to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in  connection  with the  statements  or omissions  that  resulted in such loss,
liability,  claim,  damage,  or expense as well as any other relevant  equitable
considerations.  The  relative  fault  of  the  indemnifying  party  and  of the
indemnified  party shall be  determined  by reference  to,  among other  things,
whether  the  untrue or  alleged  untrue  statement  of a  material  fact or the
omission  to state a  material  fact  relates  to  information  supplied  by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge,  access to  information,  and  opportunity to correct or prevent such
statement or omission.

                            (e) The  obligations of the Company and  Shareholder
under  this  Section  1.8  shall  survive  the  completion  of any  offering  of
Registrable  Securities in a  registration  statement  under this Section 1, and
otherwise.

                            (f)  Notwithstanding  the  foregoing,  to the extent
that  the  provisions  on  indemnification  and  contribution  contained  in the
underwriting  agreement entered into in connection with the underwritten  public
offering are in conflict with the foregoing  provisions,  the  provisions in the
underwriting agreement shall control.

                 1.9 Termination of Registration Rights. The registration rights
provided  in this  Section  1  shall  terminate  with  respect  to a  particular
Shareholder if: (A) the Registrable  Securities  owned by such  Shareholder have
been held for the  necessary  holding  period  under  Rule 144 and all shares of
Registrable Securities held by such Shareholder may be sold pursuant to Rule 144
in any three (3) month  period,  or (B) the SEC takes a position in a definitive
pronouncement  after the date hereof that (i) a Nasdaq  National  Market company
may rely on a  fairness  hearing  pursuant  to Section  25142 of the  California
Corporations  Code to avail itself of an exemption under Section 3(a)(10) of the
Act, or (ii) any securities  issued  pursuant to such a 

                                       6

<PAGE>


fairness  hearing and in reliance  upon  Section  3(a)(10)  are not deemed to be
restricted  securities  and  therefore  will be  freely  transferable.  Upon the
termination  of  registration  rights  pursuant to Section 1.9 (B),  the Company
shall have the right to  withdraw  the  registration  statement,  or any portion
thereof, covering the Registrable Securities.

                  1.10  Notice by  Selling  Shareholders. Each  Shareholder  who
intends to sell any or all of his shares of Registrable  Securities  pursuant to
the  provisions of this Section 1 shall give advance  telephonic  notice to John
Huyett, the Company's Chief Financial Officer (408-738-8881),  of such intention
and shall be free to sell any or all of his shares of Registrable  Securities if
such  Shareholder  has not  received  notice to the  contrary  within  three (3)
business hours of such telephonic notice.

                  2.  Miscellaneous.

                  2.1 General. Nothing in this Agreement, express or implied, is
intended  to confer  upon any party  other than the  parties  hereto any rights,
remedies,  obligations,  or  liabilities  under or by reason of this  Agreement,
except as expressly provided in this Agreement.

                  2.2  Governing  Law. This  Agreement  shall be governed by and
construed  under the laws of the State of  California  as applied to  agreements
among  California  residents  entered into and to be performed  entirely  within
California.

                  2.3  Counterparts.  This  Agreement  may be executed in two or
more counterparts,  each of which shall be deemed an original,  but all of which
together shall constitute one and the same instrument.

                  2.4 Titles and Subtitles.  The titles and  subtitles  used in
this  Agreement  are used for  convenience  only and are not to be considered in
construing or interpreting this Agreement.

                  2.5  Notices.   Unless otherwise provided, any notice required
or permitted  under this Agreement shall be given in writing and shall be deemed
effectively given upon facsimile (with confirmed receipt),  or personal delivery
to the party to be  notified  at the  address  indicated  for such  party on the
signature  page hereof,  or at such other address as such party may designate by
ten (10) days' advance written notice to the other parties.

                  2.6  Expenses.    If  any  action  at  law  or  in  equity  is
necessary to enforce or interpret the terms of this  Agreement,  the  prevailing
party shall be entitled  to  reasonable  attorneys'  fees,  costs and  necessary
disbursements  in  addition  to any  other  relief  to which  such  party may be
entitled.

                  2.7  Amendments and Waivers. Any term of this Agreement may be
amended and the  observance of any term of this  Agreement may be waived (either
generally   or  in  a   particular   instance   and  either   retroactively   or
prospectively),   only  with  the  written   consent  of  the  Company  and  the
Shareholders holding a majority of the Registrable Securities.

                                       7

<PAGE>

                  2.8 Severability.  If one or more provisions of this Agreement
are held to be  unenforceable  under  applicable  law, such  provision  shall be
excluded  from  this  Agreement  and  the  balance  of the  Agreement  shall  be
interpreted  as if such  provision  were so excluded and shall be enforceable in
accordance with its terms.

                  2.9 Entire Agreement.  This Agreement constitutes the full and
entire  understanding  and  agreement  between  the  parties  with regard to the
subject hereof.

                  2.10  Removal of  Restrictive  Legends.  In the event that the
registration  rights  terminate  in  accordance  with Section  1.8(B),  then the
Company shall remove any  restrictive  legends on  certificates  evidencing  the
Registrable  Securities  except for such legends relating to restrictions  under
applicable affiliates agreements.

                  Re:      Registration Statement on Form S-3

Ladies and Gentlemen:

         We have examined the Registration  Statement on Form S-3 to be filed by
Avant!  Corporation (the "Company") with the Securities and Exchange  Commission
on December 20, 1996, as thereafter  amended or supplemented (the  "Registration
Statement"),  in connection  with the  registration  under the Securities Act of
1933, as amended, of certain shares of the Company's Common Stock (the "Shares")
previously  issued to the  shareholders  of FrontLine  Design  Automation,  Inc.
("FrontLine")  in connection with the merger of a wholly owned subsidiary of the
Company with and into  FrontLine.  As your legal  counsel,  we have examined the
proceedings taken and are familiar with the proceedings  proposed to be taken by
you in connection with the sale and issuance of the Shares.

         It is our opinion that the Shares are legally and validly issued, fully
paid and non-assessable.

         We  consent  to  the  use  of  this  opinion  as  an  exhibit  to  said
Registration  Statement,  and  further  consent to the use of our name  wherever
appearing in said Registration Statement,  including the prospectus constituting
a part thereof, and in any amendment or supplement thereto.


                                       Very truly yours,

                                       /s/ Gunderson Dettmer Stough
