China's Academy of Sciences Adopts Cadence Incisive Xtreme III System to Validate Next-Generation Multi-Core Processor

SAN JOSE, CA, Jun 01 (MARKET WIRE) --
Cadence Design Systems, Inc. (NASDAQ: CDNS), the leader in global
electronic design innovation, today announced that the Chinese Academy of
Sciences Institute of Computing Technology (ICT) has adopted the
Cadence(R) Incisive(R) Xtreme(R) III System for accelerating the
development of RTL design with a verification flow for its
next-generation 64 million-plus gates Loongson III advanced multi-core
microprocessor.

The deployment of the Incisive Xtreme III System for developing the ICT's
advanced 65- and 45-nanometer multi-core processor enabled ICT engineers
to accelerate system-level verification while validating software
operations. The Xtreme III System supported the ICT's goals of
accelerating hardware/software development while reducing the risk of
costly re-spins.

"The Xtreme III System has made a significant impact in accelerating our
simulation runtime process by a factor of 860 times, and has made
co-verification a predictable process for our next-generation Loongson III
multi-core design," said Dr. Weiwu Hu, chief architect of the ICT's CPU
division. "This Cadence technology has helped us improve overall
productivity, predictability and quality of our Loongson III development."

Using Xtreme III, the ICT was able to accelerate simulation productivity
and to find at least 10 critical system-level bugs that could only be
exposed by running several billions of cycles in a system-level
environment. The system enabled early access to a flexible,
high-performance verification platform for hardware/software
co-development and delivered powerful built-in productivity features such
as hot-swap and VCD-on-Demand. These capabilities enabled ICT developers
to quickly bring up the system and find system-level bugs more simply
than through traditional debugging methods.

The ICT also used Xtreme III to augment their FPGA prototyping flow to
thoroughly address the complexity of their next-generation multi-core
microprocessors. Xtreme III fully automates compiling and partitioning,
virtually eliminating pin limitations and timing issues commonly found in
large-scale FPGA prototyping systems. The accelerated scalable
verification flow provided by Xtreme III gave ICT engineers the required
verification throughputs and ease of use while minimizing the effort
required in debugging the design in a system-level environment.

"The ICT's experience with its Loongson III design is a perfect example of
the great value hardware-based solutions like the Incisive Xtreme III
System can deliver to companies seeking greater productivity,
predictability and quality," said James Liu, Cadence general manager of
China and Hong Kong.

The Cadence Incisive Xtreme series of high-performance, high-capacity
accelerators/emulators speeds the functional verification of designs at
the behavioral, RTL, and gate levels. Designed for multi-user, multi-site,
multi-purpose systems, the Xtreme series integrates with the Incisive
simulation environment to perform advanced verification planning and to
drive coverage-based, metric-driven verification closure.
