Synopsys, ARM Introduce CCS Noise Models for ARM Physical IP

Synopsys, Inc. (Nasdaq: SNPS), a world leader in semiconductor design software and ARM [(LSE:ARM); (Nasdaq:ARMHY)], today announced that the ARM(R) Advantage(TM) , Metro(TM) and SAGE-X(TM) standard cell libraries, part of its Artisan(R) physical IP family, now support the next-generation signal integrity signoff models based on Liberty(TM) Composite Current Source (CCS) modeling technology. Used in conjunction with the Synopsys PrimeTime(R) analysis tool, the golden signoff standard, CCS noise models allow designers to get better accuracy and reduced turnaround time. Liberty open source noise models also facilitate visibility into transistor-level behavior that is key to nanometer sign-off analysis. CCS noise models are proven to deliver sign-off level accuracy to within two percent of HSPICE(R) simulation as seen at leading semiconductor companies.

“Over the years, we have closely collaborated with Synopsys to advance design solutions based on open standards,” said Brent Dichter, general manager, ARM Physical IP. “Open-source CCS modeling technology has gained significant momentum in the semiconductor industry, and we look forward to once again leading in the IP industry with CCS noise support, the next generation signal integrity models.”

CCS models are the industry’s first open-source current-based models to unify timing, signal-integrity, and power. CCS technology is designed to address the new low-power design challenges and the industry’s advanced process modeling challenges for 65-nanometer (nm) and below geometries. Other noise models suffer from limited accuracy or employ closed, proprietary formats limiting their use during signoff. In contrast, the CCS-based noise models are current-based and allow signoff tools to much more closely model actual silicon behavior, thus reducing design iterations. CCS noise models are open-source, giving users transparency and confidence during signoff and promoting interoperability across the EDA industry.

“In order for our customers to obtain the silicon entitlements of the latest processes, they need world class implementation and signoff tools as well as highest accuracy IP,” said Antun Domic, senior vice president and general manager, Synopsys Implementation Group. “The Synopsys Galaxy(TM) Design Platform combined with CCS-enabled models from industry-leading IP providers such as ARM will help ensure that our mutual customers get their silicon to function as expected and meet their challenging nanometer requirements.”

Synopsys, a member of the ARM Connected Community, will be available to discuss this collaboration at the ARM Developers’ Conference in Santa Clara, CA on October 4-5, 2006.

CCS timing and noise models for the ARM Advantage, Metro and SAGE-X standard cell libraries are available for immediate download from the ARM website.
