For Immediate Release

Synplicity's Amplify AccelArray Pro Software Qualified by Fujitsu

Amplify AccelArray Pro Software Speeds Time-to-Market and Offers Optimal Performance

SUNNYVALE, Calif., April 18, 2005 – Synplicity Inc. (Nasdaq: SYNP), a leading provider of software for the design and verification of semiconductors, today announced that the newest member of its Amplify family of structured/platform ASIC products, Amplify® AccelArray™ Pro, has received full qualification from Fujitsu Limited (Fujitsu) and Fujitsu Microelectronics America Inc. (FMA). Fujitsu and FMA will recommend Amplify AccelArray Pro as the physical synthesis solution for design and development of its AccelArray platform ASIC devices upon production release of the product.

Since announcing the joint development agreement in September 2004, Fujitsu and Synplicity have worked closely to develop custom physical synthesis uniquely targeting Fujitsu’s AccelArray platform ASICs. This customized version of Synplicity’s software enables AccelArray customers to obtain greater performance, improved densities and faster overall timing closure. With this announcement, Synplicity has now received qualification of its structured/platform ASIC physical synthesis software tools from the three leading structured and platform ASIC device suppliers: Fujitsu, LSI Logic, and NEC Electronics.

“In a relatively short amount of time, Synplicity has clearly established itself as the EDA tool vendor of choice for the three primary structured and platform ASIC suppliers,” said Andy Haines, vice president of marketing, Synplicity. “Similar to our joint development efforts with LSI Logic and NEC Electronics, in working with Fujitsu, we were able to develop a high-performance, high-capacity solution that is uniquely optimized for Fujitsu’s AccelArray devices. We believe that our customized Amplify AccelArray Pro software will provide AccelArray customers with a highly automated and user-friendly floorplanning and physical synthesis solution that allows them to obtain high-performance designs with extremely fast design schedules.”

"Fujitsu and Synplicity have worked extensively together to provide our customers a comprehensive and fully integrated structured/platform ASIC solution,” said Keith Horn, senior vice president sales and marketing, Fujitsu Microelectronics America. “The solution combines the high performance of our AccelArray architectures with highly tuned, custom physical synthesis, analysis and floorplanning from Synplicity. We are already seeing greatly accelerated timing closure and excellent performance results using our Synplicity one-pass hand-off flow. We are pleased to recommend Synplicity’s Amplify AccelArray Pro to our AccelArray customers.”

The Amplify AccelArray Pro software offers users a complete physical synthesis design solution for AccelArray devices. Through its unique understanding of the AccelArray architecture, the Amplify AccelArray Pro software enables customers to maximize the performance, density and time-to-market advantages of AccelArray devices.

Amplify Family of Structured/Platform ASIC Products
Synplicity’s Amplify family is the only physical synthesis solution that targets Fujitsu’s AccelArray and LSI Logic’s RapidChip platform ASIC products, and NEC Electronics’ structured ASIC architectures. The Amplify family of structured/platform ASIC products are the only physical synthesis tools optimized for use by front-end designers, providing the benefits of physical synthesis without having to learn complex back-end processing tasks. The tools allow a single pass hand-off to the structured/platform ASIC vendor. At the time of first hand-off to the ASIC vendor, timing tightly correlates with the final routed design, so it can be quickly closed by the vendor without costly iterations between designer and vendor.

The products directly target and understand each vendor’s unique structured/platform ASIC and typically enable 15-20 percent better speed and area improvements over conventional design flows, thereby bringing results much closer to that of standard-cell ASICs. The tools also solve the timing closure problem through the use of physical synthesis techniques and patented SNAP™ technology that ensures timing correlation and prevents signal integrity issues. The tool delivers a legally placed netlist that abides by ASIC vendor-specific design rules. The resulting benefits – high performance, low cost and shorter time to market, with greater schedule predictability – cannot be provided by generic tools. This is one of the key reasons why major structured/platform ASIC vendors have partnered with Synplicity, to ensure that customized physical synthesis tools are available for their architectures.

The Amplify family of structured/platform ASIC synthesis products received the DesignVision Award, which recognizes technologies, applications, products and services judged to be the most unique and beneficial to the industry. Synplicity’s innovative software won in the ASIC and IC Design Tools category and was recognized during DesignCon on February 1, 2005.
