                              AVANT! CORPORATION
                                 COMMON STOCK

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

   This  Prospectus  relates  to  the  public  offering,   which  is  not  being
underwritten,  of 1,857,211  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 separate  private  transactions in
which the Company acquired FrontLine Design  Automation,  Inc. and NexSyn Design
Technology 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 January 31, 1997,  the average of the high and low price for the Company's
Common Stock was $32.25 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.

Prospectus and incorporated by reference herein. 

LITIGATION RISK

   On December 6, 1995, Cadence Design Systems, Inc. ("Cadence") filed an action
titled Cadence Design Systems,  Inc. vs. Avant!  Corporation,  formerly  AscSys,
Inc.;  Gerald C. Hsu;  Mitsuru Igusa;  Opher Segev; and Chih-Liang Cheng 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  allegedly
misappropriated   and  improperly  copied  source  code  for  certain  important
functions of Avant!  place and route products from Cadence,  and that Avant! has
allegedly  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,  which were not quantified
by Cadence, 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.  The court has the matter
under  submission  and  there  has been no  ruling  on  Cadence's  motion  for a
preliminary injunction 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.  Although Avant!'s  counterclaim seeks unquantified damages according
to proof, Avant!  specifically  alleges that it has suffered losses in excess of
$500  million.  The  alleged  losses are due  largely to the decline in Avant!'s
stock market valuation caused by Cadence's alleged misconduct.

   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!,  Avant!'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
December 15, 1995,  Paul Margetis and Helen  Margetis filed in the United States
District  Court for the Northern  District of California  the  securities  fraud
class action complaint Paul Margetis and Helen Margetis, On Behalf of Themselves
and All  Others  Similarily  Situated  vs.  Avant!  Corporation;  Gerald C. Hsu;
Yuh-Zen Liao; and Stephen Tzyh-Lih Wuu. In addition,  on December 19, 1995, Fred
Tarca filed in the United  States  District  Court for the Northern  District of
California  the class action  complaint for violation of the federal  securities
laws Fred Tarca,  On Behalf of Himself and All Others  Similarily  Situated  vs.
Avant!  Corporation;  Gerald C. Hsu; Yuh-Zen Liao;  Stephen Tzyh-Lih Wuu; Jon A.
Bode; Robert C. Kagle; Tench Coxe; Wessels,  Arnold & Hendersen L.L.C. and Alex.
Brown & Sons. These class action

                                        4
<PAGE>
lawsuits allege certain  securities law violations,  including  omissions and/or
misrepresentation    of   material   facts.   The   alleged   omissions   and/or
misrepresentations  are largely consistent with the allegations  outlined in the
Cadence  claim.  These  class  action  lawsuits  are pending  resolution  of the
litigation with Cadence.

   When the lawsuits  were  originally  filed  against the Company,  the Company
experienced  delays in orders by customers due to the uncertainty of the pending
lawsuits  against  the  Company.  If the Company  suffers an adverse  outcome in
either  the  civil or  criminal  proceedings,  then  the  Company  would  likely
experience  future delays in orders from customers,  and would likely suffer the
loss of  customers.  If such  events  were to occur,  there  would be a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

   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. 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,  on 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,  a  wholly  owned  subsidiary  of  the  Company,  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,
which were acquired by Avant! in September 1996, October 1996 and November 1996,
respectively,  presents difficult  challenges for Avant!'s  management.  Each of
Avant!, Anagram, Meta and FrontLine entered into their respective

                                        5
<PAGE>

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 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

                                7
<PAGE>

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
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
(formerly  known as ArcCell),  the Company's  place and route  software  product
family, Hercules (formerly known as

                                        8
<PAGE>

VeriCheck),  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 primarily sells its products internationally in Japan, Korea and Taiwan.
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 be no  assurance  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 

                                        9
<PAGE>

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
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,  whereby the license agreement
covering the product is contained in the product  packaging but is not signed by
the user.  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 

                                       10
<PAGE>

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 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"), commonly
known as computer chips. Avant!'s objective is to establish a significant market
position as a supplier of physical design software  (software used to design the
layout of transistors  in a computer chip) 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  (less  than  0.5-micron  or  one-twenty
thousandth of a centimeter  feature size) 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 

                                       12
<PAGE>

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 Integration of Operations and Product
Lines; Management of Growth," "--Cost of Integration;  Transaction Expenses" and
"Avant! Business--Recent Developments."

   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."

   In December 1996, Avant! acquired NexSyn Design Technology Inc. ("NexSyn"), a
four-employee  start-up company that is developing  next-generation EDA software
tools (the "NexSyn  Acquisition").  Upon the closing of the NexSyn  Acquisition,
NexSyn became a wholly owned subsidiary of Avant!  and all of the  fully-diluted
shares of NexSyn capital stock and stock options were exchanged for an aggregate
of 51,282 shares of Avant!  common stock and Avant!  stock  options.  The NexSyn
Acquisition  was accounted for using the purchase  method of accounting.  Avant!
expensed  approximately  $1.3  million  in the  fourth  quarter  of 1996 for the
write-off of in-process research and development.

with  respect  to the  number of shares  of  Common  Stock  owned by each of the
Selling Stockholders.  All shares held by the Selling Stockholders as of January

from the  registration  requirements  of the Securities Act provided by Rule 506
under  Regulation D, as promulgated by the Securities  Act, and the Common Stock
issued in the NexSyn  Acquisition  was issued  pursuant to an exemption from the

thereof.  Each  Selling  Stockholder  that  acquired  Shares  from  the  Company
represented  to the Company that it was acquiring the Shares for  investment and

Registration  Statement on Form S-3, of which this Prospectus forms a part, with

                             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.
