SAN JOSE, Calif.---October 31, 2006- Atrenta, the leading provider of broad-based design analysis solutions based on industry standard SpyGlass technology, today announced that Cray (NASDAQ:CRAY), the global leader in supercomputers, has adopted its SpyGlass platform for the company's next generation ASIC projects. Using the SpyGlass platform, including SpyGlass-Constraints and SpyGlass-DFT, Cray's design teams managed to address critical issues early at RTL on a 30M gate design, thus preventing a domino effect of delays & iterations later in implementation & verification phases.

"For our large SoCs, we needed a methodology to manage the increased complexity of the designs. SpyGlass, combined with Constraints and DFT tools, is helping us jumpstart design closure at the RTL phase," said Peg Williams, Cray's senior vice president of research and development. "We selected Atrenta because its comprehensive tool suite was expected to help us resolve problems earlier in the design cycle, preventing costly downstream implementation issues. SpyGlass-Constraints enabled us to detect and correct critical issues with our design constraints including verification of false and multi-cycle paths. SpyGlass-DFT provided test coverage at the RTL-level and helped address scan and testability issues early in the design cycle. Overall, the SpyGlass tool suite provided us with state-of-the-art design analysis. We plan to continue its use into our next-generation SoCs."

"We are excited to have the market leader for supercomputers adopt Atrenta's solution," stated Dr. Ajoy Bose, Atrenta's chairman, president and CEO. "It reinforces our commitment to providing the best early design closure solution for critical design challenges. Partnering with such industry leaders as Cray gives Atrenta a keen insight into the emerging design issues to help shape our roadmap for our next-generation solutions."

About SpyGlass, SpyGlass-Constraints and SpyGlass-DFT

SpyGlass is the industry standard for early design analysis with most in-depth analysis early at RTL design phase. SpyGlass greatly reduces the late stage risks in developing complex multimillion-gate, nanometer-scale ICs, enabling companies to build better products, faster and more economically. SpyGlass accurately detects design issues at the point of creation, which is at RTL.

SpyGlass-Constraints helps early design closure by ensuring high quality implementation through constraint analysis and management, reduced manual effort with first pass constraint creation, and reduced silicon timing risk through false path validation.

SpyGlass-DFT is the first solution enabling IC designers to build testability into their designs up-front, at the register transfer level (RTL). Created specifically for logic designers, it lets users apply robust design-for-test methods and ensures high-test coverage without becoming test experts themselves. SpyGlass-DFT not only detects testability issues - it can also automatically correct them.
