Exhibit (a)(1)(G) [Mentor Logo] 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.

Wilsonville, Oregon 97070 December 6, 2001 Board of Directors of IKOS Systems, Inc. IKOS Systems, Inc. 79 Great Oaks Boulevard San Jose, California 95119 c/o Ramon A. Nunez, President and Chief Executive Officer c/o Gerald S. Casilli, Chairman of the Board of Directors 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.
