FishTail Strengthens Integration with Synopsys’ Design Compiler and PrimeTime Tools

Portland, Oregon, May 18, 2005 – FishTail Design Automation, Inc., the golden timing constraints company, today announced that it has joined the Synopsys, Inc., in-Sync® Program to provide customers with complete interoperability between FishTail’s Focus™ product and Synopsys’ Design Compiler® and PrimeTime® products. Designers import the timing exceptions generated by Focus into the Design Compiler and Prime- Time products, and by doing so are able to reduce the time taken to close timing while also improving the quality of the final chip implementation.

“Being part of the in-Sync Program is very important for us given the importance of the Design Compiler and PrimeTime tools in the market,” stated Ajay Daga, founder and CEO of FishTail. “Our customers routinely push us to strengthen our integration with these tools, and in the short time we have had access to the Design Compiler product in-house, we have already been able to take our integration to another level. Our latest 2005.04 release in production today has this tighter integration.”

“For years Synopsys has initiated programs of its own and worked with standards bodies and industry organizations to advance tool interoperability throughout the electronic design automation industry,” said Karen Bartleson, director of Interoperability at Synopsys, Inc. “Through the in-Sync interoperability program, Synopsys works with EDA vendors such as FishTail, to identify and implement optimal joint flows that maximize the productivity of our customers.”

About Focus
FishTail’s Focus™ product solves the time-consuming problem of poor chip-implementation results because of missing or incorrect timing exceptions by formally identifying false and multi-cycle paths early in the design cycle before virtual prototyping and logic synthesis. In addition, Focus also generates assertions that justify why a false-path or multi-cycle path definition is correct. Using only the synthesizable description and clock definitions, Focus automatically generates the timing exceptions for the design in standard SDC file format for use by downstream implementation tools.

About FishTail Design Automation
Founded in 2002, FishTail Design Automation has set its sights on tackling the difficult problem of precise constraints on chip timing – the area where the success or failure of a design is ultimately determined. The company’s patented technology improves chip implementation by automatically identifying exceptions to single-cycle clocking from RTL descriptions. FishTail is privately funded.
