NOT FOR IMMEDIATE RELEASE

              MENTOR GRAPHICS OFFERS TO ACQUIRE IKOS SYSTEMS, INC.

         OFFERS $11.00 IN CASH PER SHARE FOR ALL OUTSTANDING IKOS SHARES


WILSONVILLE, OR -- December 7, 2001 -- Mentor Graphics Corporation (Nasdaq:
MENT) today announced that it is offering to acquire IKOS Systems, Inc. (Nasdaq:
IKOS) 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.

"Our offer makes strategic sense for both companies," said Walden C. Rhines,
Chairman and Chief Executive Officer of Mentor Graphics. "Our acquisition of
IKOS will add to Mentor's existing products a proven and complementary emulation
product line. IKOS products provide a mid-range verification solution to
customers desiring a lower price point solution. Acquiring IKOS will also
provide Mentor with North American sales and service capabilities in the
emulation arena that we will leverage across our entire product line.

"For IKOS, our all-cash offer is clearly superior to the present agreement with
Synopsys," continued Dr. Rhines. "The Synopsys proposal is subject to onerous
closing conditions that IKOS may well not be able to satisfy in the current
environment. It is also subject to an uncertain price payable no earlier than
August 2002. Our offer is for cash at a price significantly higher than the
present trading price and can be consummated quickly, more than seven months
earlier than the Synopsys proposal."

Mentor's offer is not subject to any financing condition, and the offer is
scheduled to expire at 12:00 midnight, New York City time, on Tuesday, January
8, 2002, unless the offer is extended. Mentor beneficially owns 841,600 shares
or approximately 9.1% of IKOS' outstanding common stock. The Information Agent
for the offer is Mackenzie Partners, Inc.

The full text of the letter submitted to the Board of Directors of IKOS is
printed below.

                       Offer to Acquire IKOS Systems, Inc.

Gentlemen:

        Mentor Graphics Corporation ("Mentor Graphics") offers to acquire IKOS
Systems, Inc. ("IKOS") at a price of $11.00 per share of IKOS common stock
payable in cash.

        Summary of Offer. Our offer, which is based on publicly-available
information and is not subject to any financing condition, represents a premium
of 37% over the Nasdaq closing price of IKOS' stock on December 6, 2001, and
49.5% over the Nasdaq closing price of IKOS' stock on June 29, 2001, the trading
day before the transaction with Synopsys, Inc. was announced. Furthermore, our
offer represents a premium of 87% over the average Nasdaq closing price of IKOS'
stock for the thirty trading days ended December 6, 2001. Our all-cash offer
will enable your stockholders to receive the entire premium immediately. This
will eliminate the significant risk to your stockholders with respect to the
future performance of your business, the EDA industry, the overall stock market
or the economy generally that exists under your proposed transaction with
Synopsys.

        Our offer is not subject to the onerous closing conditions contained in
your agreement with Synopsys -- conditions that IKOS may well not be able to
satisfy in the current environment. For example, at the revenue/backlog and
profit rates of your quarter ended September 30, 2001, it is questionable
whether Synopsys would even be required to close the transaction, much less pay
your stockholders more than the $6.00 per share minimum in August 2002. In
contrast, our offer is for $11.00 per share in cash seven months earlier in
January 2002.

        The acquisition consists of a first-step cash tender offer for all
outstanding shares of IKOS common stock, followed by a second-step merger in
which IKOS' remaining stockholders would receive the same cash price per share
paid in the tender offer.

        Background. As you are no doubt aware, Mentor Graphics approached IKOS
in April 2001 to indicate its interest in making an offer for Mentor Graphics to
acquire IKOS. On several subsequent occasions, Mentor Graphics indicated its
continued interest in acquiring IKOS to IKOS and IKOS' financial advisor.

        We were therefore disappointed that you chose not to contact us prior to
your acceptance of the Synopsys agreement -- an agreement which we believe your
stockholders will find inadequate. We believe that both your stockholders and
the investment community will welcome our superior all-cash offer -- an offer
which can be consummated very quickly. We further believe that the trading price
of IKOS' stock since the announcement of your agreement with Synopsys
demonstrates that your stockholders have serious reservations about a
transaction with Synopsys.

        Superiority of Mentor Graphics Offer. The superiority of the Mentor
Graphics offer is easily demonstrated:

- -----------------------------     --------------------------------------      --------------------------------------
Certainty of Closing              Highly conditional.  There is no            Minimal standard conditions for an
                                  certainty this transaction will ever        all-cash tender offer with no
                                  close, exposing IKOS' stockholders to       financing condition; no need to wait
                                  risk of termination for more than a         until late summer 2002 to find out
                                  year; Synopsys effectively has an           whether the transaction is actually
                                  "option" to acquire IKOS.  Based on         completed.
                                  an annualization of IKOS' most
                                  recent quarterly results, it is
                                  questionable whether Synopsys will
                                  have any obligation to close the
                                  transaction.

Price                             Unknown at this time, subject to a          $11.00 per share (in cash).  Our
                                  complicated formula; based on an            price is not subject to IKOS'

                                  may not even receive $6.00 per              closing price on June 29, 2001, 37% over
                                  share.                                      the Nasdaq closing price on December 6,

                                                                              closing price of IKOS' stock for the
                                                                              thirty trading days ended December 6,
