Cadence Encounter Global Synthesis Supported by STMicroelectronics for Its ASIC Customers
ST Achieves Significant Reduction in Area with Cadence Encounter RTL Compiler in ASIC Designs

SAN JOSE, Calif., 25 Apr 2006

Cadence Design Systems, Inc. (NASDAQ: CDNS) today announced that STMicroelectronics (ST) will provide support for Cadence® Encounter® RTL Compiler synthesis in its application-specific integrated-circuit (ASIC) design methodology and flow on 90- and 65-nanometer processes for its internal and external ASIC customers.

"We have adopted Encounter RTL Compiler synthesis for production use on our STB71xx product family of set top box designs," said Thierry Bauchon, R&D director of the Home Entertainment Group at STMicroelectronics. "Encounter RTL Compiler clearly showed us significant benefits in reducing chip area, a key differentiator for us in the competitive domain of consumer electronics designs."

"After having used the Encounter digital IC design platform on several design tapeouts in our design centers in Europe, the United States and India, we have decided to support RTL Compiler for our ASIC customers using this technology," said Philippe Magarshack, group vice president and general manager of Central CAD & Design Solutions at STMicroelectronics.

Cadence Encounter RTL Compiler global synthesis has proven through tapeouts to deliver improved performance, smaller die sizes, lower power consumption, and faster design closure through place and route. Cadence defines this metric as quality of silicon (QoS). This ability to produce smaller, faster and cooler chips in less time has increased customer competitiveness and reduced overall costs.

"We are very pleased that ST, one of the world's largest semiconductor companies, has chosen to adopt Cadence's global synthesis," said Chi-Ping Hsu, corporate vice president at Cadence. "An increasing number of customers worldwide, such as ST and its ASIC customers, are selecting Encounter RTL Compiler to create complex, low power chips in less time."

Encounter RTL Compiler synthesis has been used in production by more than 150 customers worldwide for competitive markets in consumer, communications, computer, networking, graphics, and system-on-chip (SoC) designs.
