FOR IMMEDIATE RELEASE
 
  QUICKTURN RESPONDS TO MENTOR GRAPHICS' EXTENSION OF ITS UNSOLICITED TENDER
                                     OFFER
 
 QUICKTURN'S BOARD CONTINUES TO STRONGLY RECOMMEND THAT QUICKTURN STOCKHOLDERS
                            NOT TENDER THEIR SHARES
 
  SAN JOSE, CALIF. (OCTOBER 7, 1998)--Quickturn Design Systems, Inc. (Nasdaq:
QKTN) today responded to Mentor Graphics Corporation's (Nasdaq: MENT)
extension of its tender offer, which was scheduled to expire October 6, 1998,
but was extended by Mentor without its purchasing any shares tendered. Mentor
continues to own only 591,500 shares of Quickturn stock.
 
  On August 24, 1998, the Quickturn board of directors recommended Quickturn
stockholders to reject Mentor's unsolicited tender offer. The board determined
that Mentor's offer is inadequate, does not reflect the inherent value of the
Company, and is not in the best interests of Quickturn or its stockholders.
Quickturn's board continues to strongly recommend that Quickturn stockholders
not tender their shares to Mentor and urges Quickturn stockholders who may
have tendered to withdraw their shares.
