Cadence Low-Power Solution Selected for Global Unichip's PowerMagic Low-Power Design Methodology

SAN JOSE, CA--(Marketwire - August 17, 2009) - Cadence Design Systems, Inc. (NASDAQ: CDNS),
the leader in global electronic design innovation, today announced that
Global Unichip Corporation (GUC) has integrated the
CPF-based
Cadence Low-Power Solution into its PowerMagic™ methodology to optimize
the design of its customers' complex low-power ASIC implementations in
advanced technology.

GUC was able to develop a complete end-to-end low power ASIC flow,
including dynamic voltage frequency scaling (DVFS) techniques, by
integrating the Cadence® Low-Power Solution, including Cadence
Encounter® RTL Compiler, Encounter
Digital Implementation System and Encounter Conformal® Low Power,
together with its proprietary in-house tools, into the PowerMagic
methodology for design, verification, and implementation. These techniques
are keys to enabling multiple power domains of variable voltages on a
single chip and reducing voltage to circuits when peak performance is not
required.

"Our designers benchmarked the capabilities of the Cadence Low-Power
Solution by optimizing a 65-nanometer, 10-million-gate low power design
while correctly implementing more than ten power domains and over 50 power
modes," said C.C. Hsieh, vice president of Design Service at GUC. "Cadence
low power solutions worked well in GUC's integrated PowerMagic methodology,
which effectively resolved low power implementation and verification issues
that puzzled ASIC designers in a complex low power design project."

The Cadence Low-Power Solution provides a complete methodology for
design-to-signoff that begins with early design planning and includes
front-end design, synthesis and physical implementation. It enables
consistency and convergence through power estimation and analysis at every
step. Alongside the implementation flow, comprehensive power verification
is performed by leveraging static, dynamic and formal power verification
techniques in a closed-loop verification methodology. This fully
integrated, highly automated, power-aware solution is backed by
industry-leading services capabilities and the industry's largest
power-focused industry alliances -- the Power Forward Initiative and Si2's
Low Power Coalition.

"By implementing the Cadence Low-Power Solution in its PowerMagic
methodology for low-power design, GUC has delivered a tremendous
productivity and quality boost to its design teams intent on providing
superior low-power circuits to its customers," said Chi-Ping Hsu, senior
vice president of digital implementation research and development at
Cadence. "The combination should provide tremendous value to GUC's
customers."
