WILSONVILLE, OR -- February 19, 2002 - Mentor Graphics Corporation (Nasdaq:
MENT) today announced that it has extended its $11.00 per share cash tender
offer for all outstanding shares of the common stock of IKOS Systems, Inc.
(Nasdaq: IKOS) to 12:00 Midnight, New York City time, on Friday, February 22,
2002, unless further extended. The tender offer was previously scheduled to
expire at 12:00 Midnight, New York City time, on Friday, February 15, 2002.

As of the close of business on February 15, 2002, 637,603 shares of IKOS common
stock had been validly tendered into the offer, which, together with the 841,600
shares already beneficially owned by Mentor, represents approximately 15.6% of
IKOS' outstanding common stock (based upon 9,459,132 shares outstanding as of
January 10, 2002). The shares tendered represent approximately 6.7% of the
outstanding common stock.

As announced on December 7, 2001, Mentor Graphics offered to acquire IKOS
Systems for $11.00 in cash per share of IKOS common stock. The offer represents
a premium of 37% over the Nasdaq closing price of IKOS stock on December 6, 2001
and a premium of 49.5% over IKOS' closing price on June 29, 2001, the last
trading day before IKOS announced its proposed acquisition by Synopsys, Inc.
(Nasdaq: SNPS). Furthermore, the offer represents a premium of 87% over the
average closing price of IKOS stock for the thirty trading days ended December
6, 2001. In addition, Mentor's offer is subject to fewer conditions than the
Synopsys proposal and can be consummated months earlier than the Synopsys
