MOUNTAIN VIEW, Calif. and HSINCHU Taiwan, -November 21, 2005 - Synopsys, Inc. (Nasdaq:SNPS), a world leader in semiconductor design software, and UMC (NYSE: UMC; TSE: 2303), today announced the availability of a 90-nanometer (nm) reference design flow that is optimized for low-power system-on-chip (SoC) designs. The validated RTL-to-GDSII design flow is based on Synopsys' Galaxy^TM Design Platform, ARM® Artisan® SAGE-X^TM standard cell library, and UMC's 90-nm process. It addresses leakage power challenges at 90 nm and provides advanced design-for-manufacturing (DFM) capabilities for faster yield ramp and lower development costs.

"At UMC, we recognize the importance of working with leading EDA companies such as Synopsys to deliver silicon-validated reference design flows that address the SoC design challenges encountered at nanometer technologies," said Ken Liou, director of the IP and Design Support Division at UMC. "This latest development with Synopsys is specifically designed to give customers the benefit of both companies' expertise to help them achieve first pass silicon success with reduced time and risk."

The reference design flow incorporates many of Synopsys' Galaxy Design Platform's low power and design-for-manufacturing innovations, including Power Network Synthesis (PNS) and Power Network Analysis (PNA) products, which are used to design power plans at the floorplanning stage. Other floorplanning capabilities include virtual flat floorplanning with physical hierarchy-aware global routing, virtual timing optimization, and macro placement with automatic hierarchy detection. Designers can create an optimized initial design floor plan using these advanced features to guide them to the next design steps in physical synthesis and place and route. By following this plan, designers can achieve faster timing closure and avoid design iterations. The reference design flow also features multi-threshold (MVth) optimization to take advantage of the available UMC 90-nm multi-threshold libraries for leakage power reduction. In addition, the flow supports advanced signal integrity capabilities to perform analyses for electro migration (EM) and voltage drop (IR) that are crucial in avoiding design failure in 90-nm and below designs.

"Our close relationship with UMC helps ensure that the reference flow will satisfy the demands of even the most advanced designers dealing with 90-nanometer process design issues in power optimization and design for manufacturing and yield," said Rich Goldman, vice president of Strategic Market Development at Synopsys. "This collaboration builds upon UMC's advanced technology and Synopsys' Professional Services proven expertise to give designers access to an optimized path to silicon that delivers higher quality of results while speeding time to results."

Synopsys has brought several new DFM capabilities to the new 90-nm reference design flow. One example is the addition of timing-driven dummy metal insertion to specifically meet UMC's metal density requirements while maintaining timing closure, and automatic redundant via and via farm insertion. These new DFM capabilities can help designers improve reliability and are supported in Synopsys' place-and-route solution.

The UMC/Synopsys reference design flow is available now and can be accessed from UMC's website at http://www.umc.com.
