Cadence and Sun Extend Collaboration and Announce Broad Support For EDA Applications.

SANTA CLARA, Calif. & SAN JOSE, Calif. -- Cadence Offers EDA Applications on Sun Solaris 10 for SPARC- and x64-Based Platforms to Boost 90 nm Electronic Design Success

Sun Microsystems, Inc. (NASDAQ:SUNW) and Cadence Design Systems, Inc. (NASDAQ:CDNS) today announced that Cadence is the first electronic-design-automation (EDA) technology vendor to provide broad support across its product lines for the Solaris(TM) 10 Operating System (OS) for AMD Opteron(TM) and Sun UltraSPARC(R) processor-powered Sun Fire(TM) clients and servers. In addition, the companies have extended their long standing business relationship with the signing of a multi-year contract for Cadence products and services, and agreed to develop additional solutions that address design challenges at 90 nanometers and beyond.

Cadence will be supporting both desktop and server applications from their EDA product line for integrated circuits. With this broad support, Cadence will offer over sixty applications on four different platforms for the Solaris 10 OS.

"This collaboration is yet another illustration of Sun's steadfast commitment to the EDA and desktop markets. We are very pleased that Cadence has chosen to support the Solaris 10 OS," said Stephen Borcich, vice president, Partner Marketing, Sun Microsystems. "As a result of dedicated investments in engineering and testing focused on product interoperability, performance optimization and timely delivery, Cadence customers will be able to easily run Solaris 10, the most advanced operating system on the planet. The key features of the Solaris 10 OS, including Dynamic Tracing and Solaris(TM) Containers, running on SPARC and x64 processor-based Sun Fire servers, will help our customers get better service levels and application performance, as well as protect their software investment."

"Cadence works with industry-leading partners to help customers address their most pressing design challenges," said Ajay Malhotra, senior vice president of Marketing at Cadence Design Systems. "Today's news demonstrates Cadence and Sun's ongoing commitment to help customers with their EDA design challenges while leveraging the compelling benefits of the Solaris 10 OS on SPARC and x64 Sun Fire systems."

In response to customer demand, Cadence will broaden support for the Cadence(R) Encounter(R) digital IC design platform, the Virtuoso(R) custom design platform, the Incisive(R) functional verification platform, and Cadence Design for Manufacturing (DFM) technologies to include the Solaris 10 OS on Sun Fire x64 (x86, 64-bit) servers and clients powered by AMD Opteron processors. Cadence will provide customers with high performance and scaling, proven high-grade security and a leading high-availability platform with a choice of AMD Opteron, Sun UltraSPARC or Intel processors, all supporting the Solaris 10 OS.

"With Cadence now supporting the Sun Solaris 10 OS for Sun Fire x64 platforms, our investment is protected with guaranteed compatibility," said Mike Hames, senior vice president, Application Specific Products, Texas Instruments. "The same operating system operates on both x86 and x64 systems, with platform feature parity between UltraSPARC-based platforms and x64 systems. This will help TI to continue delivering quality silicon to our customers."

As Sun expands its already significant commitment to Cadence solutions, customers stand to benefit through each company's customer acceptance practice, where customers input directly into product development, as well as binary compatibility and continued support of innovative joint technologies.
