Synopsys' Proteus Optical Proximity Correction Software Delivers Near Linear Performance Increase Using 1000 Intel® Xeon™ Processors
Scalable Distributed Processing Significantly Reduces OPC Processing Time

Synopsys, Inc. (NASDAQ: SNPS), the world leader in semiconductor design software, today announced significantly improved performance of its Proteus™ optical proximity correction (OPC) software through its distributed processing capability on the Intel® Xeon™ architecture. With demonstrated near- linear scalability when distributed on more than 1000 Intel Xeon processors, Proteus can now reduce the time to obtain OPC results from days to hours on advanced 90-nanometer (nm) and 65nm integrated circuits (ICs). Synopsys' leading semiconductor customers have taped out complex designs containing over 500 million transistors with Proteus on thousands of Intel Xeon-based compute servers.

"We are pleased to see leading EDA applications like Proteus optimized for Intel® Architecture based systems to drive significant improvements in silicon design," said Guru Bhatia, IT Engineering Computing Director, Intel Corporation. "Highly scalable large compute environments based on Intel Xeon processors offer higher performance and faster throughput required to design complex silicon products at a lower cost.

"Proteus has become critical to ensure the manufacturability of the most advanced semiconductor designs," said Sandeep Khanna, vice president of the design for manufacturing group at Synopsys. "The ability to achieve accurate OPC results on a complete design in less than twelve hours is crucial for most of our customers. Proteus' scalable distributed processing, combined with Intel Xeon processors, delivers on this goal."

Synopsys will offer live demonstrations of Proteus' scalability on 80 Intel Xeon processors at 3.06 GHz, in a rack at SPIE's Microlithography 2004 Conference in booth #820 at the Santa Clara Convention Center on February 24 and 25, 2004.
