Synplicity ASIC Synthesis Product Offers Support
For Leading ASIC Design Tools and IP Libraries

New Synplify ASIC Product Flow-Tested With Physical Design and Test Tools

SUNNYVALE, Calif., June 4, 2001 - Further detailing its strategy to deliver a high-productivity synthesis solution for ASIC designers, Synplicity Inc. (Nasdaq: SYNP), a leading supplier of software for the design and verification of semiconductors, today announced that its new Synplify ASIC software has been flow-tested with leading test and physical design tools, and is supported by leading library vendors. With this compatibility, Synplicity ® has made it easier for designers to integrate the Synplify ASIC synthesis product into existing design flows. To date, the Synplify ASIC product has been flow tested with physical design and test products from Avant!, Cadence, Monterey Design Systems, Synopsys and SynTest Technologies, either directly by Synplicity or by customers using the Synplify ASIC software. Library partners supporting the Synplify ASIC product include Artisan Components, Inc. and Virtual Silicon.

"We developed the Synplify ASIC product with runtimes up to 15 times faster than traditional synthesis products to deliver an order of magnitude productivity improvement to our customers, said Andy Haines, vice president of marketing at Synplicity. "Compatibility between design tools is as important to designer productivity as a fast and easy to use synthesis product. As part of our commitment to improve designer productivity, we will continue to improve the interoperability between our products and others in the design flow."

Test Tool Compatibility

Testing design functionality and performance is a critical component of ASIC design. To enable successful handoff between leading test tools and the Synplify ASIC product, Synplicity tested flows with Synopsys' Test Compiler and TetraMax products; SynTest's TurboScan, TurboBSD and TurboFault products; and is working to test flows with LogicVision's embedded test products.

"SynTest and Synplicity have been working together for several months to provide a complete solution for our customers." said L. T. Wang, president and CEO, SynTest. "We are pleased that our customers now have a productivity-focused synthesis solution with proven scan and Logic BIST insertion capability."

Synplicity also is working closely with LogicVision to establish a compatible flow between the companies' products. LogicVision's director of business development, Steve Baird, said, "LogicVision and Synplicity both share the same goal, to provide our customers with a high-productivity solution to their design needs. We are currently investigating flow interoperability to ensure our shared customer's embedded test needs are supported."

Physical Design Tool Support

Synplicity and Monterey Design Systems developed a high-productivity design flow which combines Synplicity's Synplify ASIC synthesis software with Monterey's Sonar and Dolphin physical design software, enabling ASIC designers to shave months off of design time and determine timing closure early in the design process. The register transfer level code to a final GDS II output for manufacturing design flow is detailed in a separate announcement also made today.

Additionally, Synplicity has worked with ASIC design customers to confirm interoperability between the Synplify ASIC product and Cadence's Silicon Ensemble and Avant!'s Apollo products.

Library Partners

In addition to confirming design flows with leading tool vendors, Synplicity has also established support from the two leading library vendors, Virtual Silicon and Artisan Components.

Ken Brock, director of marketing, Virtual Silicon, stated, "With Synplicity as part of our EDA Ambassador program, Synplify ASIC customers have the full support of Virtual Silicon in realizing the tremendous design productivity advantages of the Synplify ASIC product."

Michael Ma, senior director of end-user program at Artisan Components, added, "Synplicity has been a member of our EDANet program for several months, and during that time we have been pleased to see Synplicity's successful beta testing and early customer acceptance with the Synplify ASIC product. We plan to continue our efforts together to support our mutual customers."

About Synplicity's Synplify ASIC Product

Synplify ASIC is the industry's first timing-driven ASIC synthesis product optimized to improve productivity for the majority of ASIC designers. Leveraging Synplicity's proprietary synthesis algorithms that have made Synplicity's FPGA synthesis and ASIC verification products successful, the Synplify ASIC software provides an extremely fast, easy-to-use and powerful ASIC synthesis solution with runtimes up to 15 times faster than traditional synthesis products. The Synplify ASIC software also offers a unique "top-down" design methodology that enables designers to perform timing-driven synthesis on up to two-million-gate designs in a single operation, supporting matching hierarchy and constraints in synthesis and place and route steps.
