Tharas Systems Adds Support for Verisity's eCelerator; Tharas Joins Verisity's VIP Program

MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--July 23, 2003--Verisity Ltd. (Nasdaq:VRST), the leading supplier of verification process automation solutions, and Tharas Systems, a provider of high-performance hardware-assisted design verification, today announced that Tharas has joined Verisity's Interoperability Partners (VIP) program to develop an integration between the Hammer(TM) hardware accelerator and Verisity's eCelerator(TM) testbench acceleration tool. An integrated solution between eCelerator and Tharas' Hammer hardware accelerator will provide users with significantly faster verification in a single environment for RTL and testbench acceleration.

"Tharas' patented custom processor-based technology enables users to accelerate RTL, gate and some behavioral constructs while maintaining the ease-of-use and debug productivity of software simulators," said Sanjay Sawant, director of marketing and business development at Tharas Systems. "By integrating Hammer with Verisity's eCelerator, users will now be able to accelerate a majority of their testbench, while keeping all of the power of Specman Elite."

Tharas Systems' Hammer provides Verilog, VHDL and mixed-language accelerated simulations while offering the industry's fastest compile, ease-of-use and debug capabilities comparable to that of software simulators. Verisity's eCelerator combines the power of the Specman Elite(R) verification process automation with the high performance of hardware-assisted verification. An integrated solution between Hammer and eCelerator enables engineers to synthesize and accelerate their testbenches written in the e verification language onto Hammer's custom processor engine. This integration enables engineers to bring hardware verification earlier into the design process and use a single environment throughout the verification flow.

"An integrated solution between Hammer and eCelerator provides verification engineers working at the system level with an automated method of ensuring that their design works in the system environment, before going to silicon. Hammer enables our mutual customers to turn multiple designs in a day," said Dave Tokic, director of strategic marketing for Verisity. "We welcome Tharas to the VIP program and look forward to working with them to provide our mutual customers with a single, automated verification flow."
