Topographical Technology Improves Designer Efficiency and Reduces Turnaround Time

　　MOUNTAIN VIEW, Calif., August 21, 2006 - Synopsys, Inc. (Nasdaq: SNPS), a world leader in semiconductor design software, today announced that Progate Group Corporation (PGC), one of the largest SoC/ASIC design service providers in Taiwan, has adopted Synopsys' Design CompilerR topographical technology to help accelerate time-to-market for its products. Topographical technology accurately predicts post-layout design performance early in the design cycle, enabling designers to identify and fix issues during RTL synthesis. By eliminating time-consuming iterations between RTL synthesis and physical layout, PGC designers are able to close on their performance goals quickly and more efficiently.

　　"Topographical technology streamlines the design process by giving our RTL designers visibility into post-layout design issues without having to learn or run physical implementation tools," said Jasper Lee, technical manager at PGC. "The results we have seen using topographical technology correlate within two to six percent of actual layout timing and area. This tight correlation enables our designers to achieve desired performance faster, reducing total design time up to four weeks."

　　Topographical technology accurately predicts interconnect delays by utilizing Synopsys' physical implementation technologies rather than approximations, also known as wire-load models. In addition, topographical technology incorporates clock-tree synthesis technology to accurately estimate post-layout power consumption. This extends topographical technology correlation beyond timing and area to include leakage and dynamic power.

　　"Topographical technology continues our strong tradition of bringing to market innovative synthesis technologies," said Antun Domic, senior vice president and general manager of Synopsys' Implementation Group. "Design Compiler customers are benefiting from a highly-correlated RTL-to-GDSII flow that significantly reduces their design cycle time and helps them stay competitive in today's market."
