Mentor Graphics Delivers Enhanced 0-In Clock Domain Crossing and Formal Verification Technology

WILSONVILLE, Ore., May 8, 2007 – Mentor Graphics Corporation (Nasdaq: MENT) today announced the immediate availability of version 2.5 of the 0-In® Clock Domain Crossing (CDC) and Formal Verification products. This new release includes significant technology enhancements allowing customers to apply advanced assertion-based verification techniques across a wider range of design types more efficiently. Specifically, the enhancements deliver increased performance and capacity to enable a more rapid means of finding and correcting critical bugs prior to committing designs to silicon. Moreover, through a much improved graphical analysis and debug environment customers can be more productive in resolving the toughest bugs in their chips.

Mentor continues to give significant attention to Clock Domain Crossing (CDC) analysis and Formal Verification technology as it strives to meet the challenges of functional verification. To enable a more comprehensive functional verification solution, the CDC and Formal Verification technologies delivered in 0-In Release 2.5 are tightly integrated with the Questa™ advanced verification platform.

CDC and Formal Verification Technology Enhancements
With this release, the CDC verification functionality more efficiently supports a hierarchical methodology that enhances the performance and capacity of CDC analysis and allows the tool to scale with the size of the design. Additionally, enhancements to the core CDC analysis technology deliver improved support designs with multiple modes allowing users to visualize CDC analysis results across all valid combinations of modes in the design.

The Formal Verification functionality has been enhanced with a new edge-based clock model that enables users to accurately model designs with multiple asynchronous clocks. This new clock model expands the capacity of formal exploration by 2 – 10 times depending on the design. Additional proof engines enable users to prove a new class of design properties by integrating multiple formal engines within one tool.

"We have a very strong commitment to deliver excellent technology and exceptional support through our 0-In product portfolio,” said Robert Hum, vice president and general manager of Mentor Graphics Design Verification and Test division. “Our customers face tremendous verification challenges and the 0-In tools address some of the most critical verification areas.”
