               MENTOR GRAPHICS SUCCESSFULLY COMPLETES TENDER OFFER
                             FOR IKOS SYSTEMS, INC.

              MENTOR GRAPHICS ANNOUNCES SUBSEQUENT OFFERING PERIOD



WILSONVILLE, OR - March 27, 2002 - Mentor Graphics Corporation (Nasdaq: MENT)
today announced the purchase of 7,836,636 shares pursuant to its tender offer
for the publicly-held shares of common stock of IKOS Systems, Inc. (Nasdaq:
IKOS) and the commencement of a subsequent offering period for the remaining
shares at a price of $11.00 per share.

The initial offering period expired at 12:00 midnight New York City time, on
March 26, 2002. Based on preliminary information from the depositary for the
offer, as of the close of business on March 26, 2002, 7,836,636 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
85.63% of IKOS' outstanding common stock (based upon 10,134,944 shares
outstanding as of March 25, 2002). The shares tendered also represent
approximately 82.70% of IKOS' common stock on a fully-diluted basis (based upon
10,493,783 fully-diluted shares as of March 26, 2002), thereby satisfying the
tender offer condition that more than 50% of the fully-diluted common stock of
IKOS be tendered. Fresno Corporation, the wholly-owned subsidiary through which
the tender offer was made, has accepted for payment all validly tendered shares
and will make payment to the depositary for the accepted shares promptly.

In addition, pursuant to Rule 14d-11 of the Securities Exchange Act, Mentor and
Fresno have elected to provide a subsequent offering period, which commences
today and will expire at 12:00 midnight New York City time on the earlier of (1)
the date upon which shares of IKOS' common stock validly tendered and not
withdrawn, together with shares of IKOS' common stock then owned by Mentor and
Fresno, represent at least 90% of IKOS' outstanding common stock or (2) Tuesday,
April 23, 2002. IKOS stockholders who have not yet tendered their shares may do
so at any time prior to the expiration of the subsequent offering period. All
shares properly tendered during the subsequent offering period will be accepted,
and tendering stockholders will be paid $11.00 per share in cash promptly
following acceptance. No shares tendered in the subsequent offering period may
be withdrawn after tender.

As soon as practicable after the expiration of the subsequent offering period,
IKOS will be merged with and into Fresno Corporation with the surviving company
becoming a wholly-owned subsidiary of Mentor. If after the expiration of the
subsequent offering period, Mentor and Fresno have acquired at least 90% of the
then outstanding IKOS common stock, the merger will be accomplished under
short-form merger procedures without a vote of IKOS stockholders. Following this
merger, all remaining IKOS stockholders who did not tender their shares in the
tender offer will receive the same $11.00 per share in cash paid in the tender
offer. Mentor will promptly mail relevant information to these stockholders on
how to receive payment for their shares.
