Synopsys Donates Technology for Low Power Design to Accellera Standards Organization
Technology Proven to Help Customers Achieve Ultra Low Power IC Designs

Synopsys, Inc. (NASDAQ: SNPS), a world leader in semiconductor design software, today announced that it has donated power management technology to Accellera, the Electronic Design Automation (EDA) organization focused on electronic design automation standards. The donation includes power management commands, SystemVerilog constructs, VHDL constructs, and the Switching Activity Interchange Format (SAIF), all in support of Accellera's Unified Power Format technical subcommittee's efforts. Under the Unified Power Format activities, the design community, EDA tool suppliers and standards bodies are working together to produce an open and inclusive standard for low power design by January 2007.

"The donation by Synopsys to the Unified Power Format technical subcommittee is much appreciated and complements donations from other Accellera members," said Shrenik Mehta, Accellera chair. "We look forward to delivering a standard based on industry-wide contributions that will quickly meet the demands of end-customers."

Synopsys is an industry leader in providing solutions for low power design automation. Its low power solutions have been proven through multiple successful advanced low power tapeouts to enable customers to develop more competitive products. The Synopsys Galaxy™ and Discovery™ platform solutions for low power design span RTL synthesis, physical implementation, verification, and analysis. This allows simulation of power-down blocks, equivalency- and design-checking of advanced low power designs, inference of consistent constraints as early as possible, and communication of the designer's power intent throughout the entire design and verification flow.

"Many customers worldwide utilize Synopsys' low power technology to produce their most advanced low power designs," said Rich Goldman, vice president of Strategic Market Development at Synopsys, Inc. "By contributing our technology to the Accellera Unified Power Format technical subcommittee, Synopsys demonstrates its dedication to allow all designers and EDA suppliers to utilize its proven technology as a comprehensive standard for low power design."
