Verisity Delivers Latest Version Of eCelerator; eCelerator Speeds STMicroelectronics' Verification by 75x

MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--June 23, 2003--Verisity Ltd. (Nasdaq:VRST), the leading supplier of essential technology and methodology for functional verification, today announced eCelerator(TM) version 1.1. eCelerator combines the power of the Specman Elite(R) testbench automation solution with the high performance of hardware-assisted verification, providing users with a significant increase in verification performance. eCelerator version 1.1 features improved symbolic control flow analyses, yielding an order of magnitude improvement in compile time of complex e language programs. Version 1.1 also has improved error handling, more automation and added support for nested lists. The latest version of eCelerator has been in use on real customer designs and has sped the verification process anywhere from 25 to 75 times over a pure simulation-based environment.

STMicroelectronics has adopted eCelerator for use on their ASEF project and has seen significant success with the testbench acceleration solution. "eCelerator streamlines our system-level verification environment and enables us to make better use of our hardware verification platform by bringing it earlier into the verification flow," said Francesco Sforza, dynamic verification manager, Central R&D for STMicroelectronics. "Additionally, a key benefit that we have seen with eCelerator is its performance. We recently benchmarked a 75x improvement over our previous methodology -- something that we are delighted to report!"

eCelerator Technology

eCelerator enables users to accelerate their verification by synthesizing and accelerating the most time-consuming parts of their e verification language testbench on hardware verification platforms. It retains access to all of the power of Specman Elite, providing users with a high degree of visibility into their design and complete consistency between their software simulations and accelerated simulations. This enables a single flow from simulation to emulation without requiring any changes to the e testbench.

"eCelerator is vital technology for system-level verification as it gives verification engineers the ability to perform hardware/software co-verification, emulation, acceleration, simulation and testbench automation all within the same environment," said Sylvie Hurat, strategic marketing manager for Verisity. "This, coupled with the substantial boost in verification performance makes eCelerator one of a kind technology."

eCelerator supports the following hardware emulation/acceleration systems: Celaro(TM) and VStation hardware emulators from Mentor Graphics Corporation, and the Incisive Accelerator/Emulator Platform, or Palladium, from Cadence Design Systems.
