Cadence Design Systems and Mentor Graphics Win DesignVision Award for Open Verification Methodology

SANTA CLARA, Calif., Feb. 5, 2008 – Cadence Design Systems, Inc. (NASDAQ: CDNS) and Mentor Graphics Corp. (NASDAQ: MENT) today announced that the Open Verification Methodology (OVM), developed jointly by the two companies, was awarded the Best Design Verification Tool DesignVision award by the International Engineering Consortium (IEC). DesignVision awards are given to pay tribute to the best design verification technology in the semiconductor industry. The OVM was also recently awarded a “2007 BEST” award for EDA technology from Electronic Design Magazine.

“The DesignVision award recognizes the innovation and industry impact of the Open Verification Methodology, which has been downloaded by hundreds of companies in just its first few weeks,” said Michal Siwinski, group marketing director for Advanced Verification at Cadence. “The OVM is already seeing great interest and praise, and we expect its success to continue to grow during the remainder of 2008.”

“As the first open, language-interoperable, SystemVerilog verification methodology in the industry, the OVM represents a major step forward in protecting our customers’ investment in verification,” said Robert Hum, vice president and general manager of Mentor Graphics Design, Verification and Test Business Unit. “We are pleased that the OVM has been honored with this award for the solutions it provides.”

The OVM, based on IEEE Std. 1800™-2005 SystemVerilog standard, provides a methodology and accompanying library that allow users to create modular, reusable verification environments in which components communicate with each other via standard transaction-level modeling interfaces. It also enables intra- and inter-company reuse through a common methodology and classes for virtual sequences and block-to-system reuse, and full integration with other languages commonly used in production flows. Distributed under the standard open-source Apache™ 2.0 license, the OVM source code, documentation, and use examples may be downloaded free of charge from http://www.ovmworld.org.
