Press Release Summary = Synopsys, Inc. (Nasdaq: SNPS), a world leader in
semiconductor design software and ARM [(LSE:ARM); (Nasdaq:ARMHY)], today announced
that ARM® AdvantageT , MetroT and SAGE-XT standard cell libraries, part of ARM's
Artisan® physical IP family, now support the next-generation signal integrity
signoff models based on LibertyT Composite Current Source (CCS) modeling technology.
Used in conjunction with the Synopsys PrimeTime® 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® simulation as seen at leading semiconductor companies.


Press Release Body = Next-Generation Signal Integrity Sign-off Models to Deliver
Improved Accuracy and Reduced Turnaround Time



Bangalore-October 4th, 2006-Synopsys, Inc. (Nasdaq: SNPS), a world leader in
semiconductor design software and ARM [(LSE:ARM); (Nasdaq:ARMHY)], today announced
that ARM® AdvantageT , MetroT and SAGE-XT standard cell libraries, part of ARM's
Artisan® physical IP family, now support the next-generation signal integrity
signoff models based on LibertyT Composite Current Source (CCS) modeling technology.
Used in conjunction with the Synopsys PrimeTime® 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® 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 GalaxyT 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. For more information, please visit www.arm.com/developersconference.
