Mentor Graphics Consulting Organization Builds on Verification Expertise through Agreement with TransEDA

WILSONVILLE, Ore., May 1, 2002 - Mentor Graphics Corporation (Nasdaq: MENT) today announced a partnership agreement with TransEDA®, a leader in ready-to-use verification solutions for electronic designs, that provides Mentor Consulting with access to TransEDA's coverage analysis and HDL checking tools. Part of Mentor's expanded focus on consulting for functional verification, this agreement allows its consultants to build on their expertise and develop and test new flows and methodologies that are deployed for Mentor's customers.

As the complexity of SoC (system-on-chip), ASIC (application-specific integrated circuit) and FPGA (field-programmable gate array) designs has continued to increase, verification processes have also become more complex. Today companies are finding that verification accounts for as much as 80 percent of the design process. Recognizing the need for improved verification solutions, Mentor delivers methodology consulting on all aspects of the verification process. In order to help companies ensure higher quality and better predictability of design performance through the management of verification, Mentor Consulting is expanding on its expertise by testing and developing new methodologies and flows and training its consultants on the best tools available.

"Verification is becoming the largest concern facing our customers and success requires both good tools and effective methodologies," said Phil Bishop, vice president and general manager of Mentor's Consulting division. "In order to help our customers establish the best possible methodologies, we must continually build on our knowledge of best-in-class tools that have a synergistic relationship with Mentor's offerings."

"Mentor's consulting organization is well-respected in the industry for the knowledge and expertise of its consultants," said Tom Borgstrom, vice president of marketing, TransEDA. "Mentor's consultants now have access to our best-in-class tools so they can help our common customers design and implement leading-edge verification methodologies."

Mentor Consulting sought access to TransEDA's VN-Check™ configurable HDL checking and VN-Cover™ coverage analysis tools because checking and coverage help engineers find bugs faster and TransEDA's solutions are ready to use with a wide variety of design and verification environments, including Mentor's industry-leading verification tools. VN-Check provides hundreds of design checks in predefined or user-created rules sets that uncover Verilog and VHDL design and coding problems before simulation. The leading coverage analysis tool in the industry, VN-Cover supports Verilog, VHDL and dual-language simulation to provide objective feedback on the state of verification with a variety of code and finite state machine (FSM) coverage metrics. VN-Cover is compatible with all of the leading simulators, including Model Technology's ModelSim® tool from Mentor Graphics®.

In addition to verification, Mentor Consulting also partners with TransEDA in the area of IP qualification. Mentor Consulting will integrate tools such as VN-Cover into its IP qualification services. These services offer customers a comprehensive solution for measuring IP quality based on industry standards and best practices.
