MOUNTAIN VIEW AND SUNNYVALE, Calif., May 24, 2007 — Synopsys (Nasdaq: SNPS), a world leader in semiconductor design software, and Synplicity, Inc. (Nasdaq: SYNP), a leading supplier of software for the design and verification of semiconductors, today announced the signing of a joint marketing agreement intended to improve verification flows for their mutual customers.  Under terms of the agreement, the companies intend to work together on next-generation, high-performance verification solutions for ASIC designers.  Targeting FPGA-based prototyping environments, Synopsys and Synplicity plan to demonstrate Synopsys’ VCS® RTL functional verification solution working seamlessly with Synplicity’s new Identify® Pro software with TotalRecall™ technology, a tool adding full visibility to FPGA-based prototyping systems.  A press release announcing Synplicity’s Identify Pro software was distributed today (Synplicity Delivers Breakthrough ASIC Verification Solution).
 
“Synplicity and Synopsys are focused on improving verification flows for the ASIC design community,” said George Zafiropoulos, vice president of Marketing, Discovery Verification Platform, Synopsys.  “Working together we are able to deliver a solution that can increase productivity for FPGA-based prototyping of ASIC designs.  The Synopsys VCS solution and the Synplicity Identify Pro product will enable our mutual customers to more quickly perform interactive debugging of FPGA-based prototypes.”

“We believe the collaboration between Synplicity and Synopsys will result in innovative new hardware-assisted verification flows,” said Joe Gianelli, vice president, Business Development and Strategic Alliances, Synplicity.  “We have been working with Synopsys during the past six months to ensure that our new Identify Pro software and Synopsys’ industry-leading VCS solution work seamlessly together to provide full visibility for high-performance ASIC prototyping flows.  Using this flow will enable
designers to find and debug design issues that are otherwise only caught using live system stimulus.”

The Synopsys-Synplicity joint marketing agreement grants both companies licenses of their respective products to create a highly tested flow between their respective tools.  Under the terms of the agreement, Synopsys and Synplicity intend to explore additional capabilities from each company’s product portfolio to advance their combined, next-generation verification solutions. 

Synplicity and Synopsys will be exhibiting at the 2007 Design Automation Conference, June 4-7 in San Diego, California.  Synopsys will be in booth # 5278.  Synplicity will be in booth # 4278 and plans a demonstration of the Synplicity-Synopsys integrated ASIC prototype flow.
