SANTA CLARA, Calif.—(BUSINESS WIRE)—Feb. 21, 2006— Tensilica(R), Inc., today announced that the company has worked with Cadence Design Systems, Inc. (Nasdaq: CDNS) to provide mutual customers with a predictable design path from RTL to first silicon. The Tensilica-Cadence Encounter(R) RTL-to-GDSII methodology streamlines the development of SoC designs based on the Tensilica's new Diamond Standard processor family. The Diamond Standard processor family includes six cores, ranging from a low-power 32-bit controller to the industry's highest performance DSP. Tensilica also announced that it is now a member of Cadence's OpenChoice IP program. The OpenChoice IP program enables IP interoperability, facilitates collaboration, and provides access to leading IP providers for Cadence customers.

The Encounter digital IC design platform integrates global RTL and physical synthesis, high performance SI-aware routing, and sophisticated nanometer analysis and optimization. It is ideal for large scale, low power, yield-sensitive, and other demanding design challenges and is production-proven through the 65nm node.

"The Encounter platform is a popular RTL-to-GDSII implementation system for designing low power as well as high performance SoCs. By supporting Diamond Standard cores based on Tensilica's Xtensa(R) architecture in this methodology, we give yet another advantage to our customers to design these cores into their SoCs," stated Eric Filseth, VP of Product Marketing, Cadence Design Systems. "With this methodology, our customers should be able to save weeks off their design cycles."

"Many of our customers use Cadence technology," stated Larry Przywara, Tensilica's director of strategic alliances. "Our teamwork with Cadence enables us to provide our mutual customers with a predictable path from RTL to better first silicon."
