Testbench integrated on emulator

Verisity Ltd continues to integrate the hardware-based verification products acquired with Axis Systems Inc. into its own testbench generation tool to create SoC design solutions. The company bares SpeXtreme, which aims to let designers implement testbench functions on Xtreme emulation hardware to speed verification.

Verisity acquired Axis Systems last year and vowed to merge its testbench generation technology with Axis' environments. It completed step one with the launch of SpeXsim, which integrated Verisity's Specman Elite testbench generation environment with Axis' Xsim simulator.

The new SpeXtreme system combines Verisity's eCelerator testbench synthesizer with Axis' Xtreme-II and Xtreme Server acceleration and emulation hardware. SpeXtreme will spare design teams from running eCelerator testbenches on a workstation and then connecting to the design under test running on an Xtreme emulator, said Yaron Kashai, vice president of research and strategic technology at Verisity. With SpeXtreme, designers can use Verisity's eRCC compiler to generate testbenches that will run directly on the Xtreme emulator/accelerator. "We're migrating the slow components of the software onto the hardware," said Kashai. The eRCC product, he said, "reads in the verification environment and compiles speed-critical portions, then migrates them onto the Xtreme-II platform."

Tweaking the slower and timing-critical components of a design in this way will provide a 20x to 100x increase in verification speed over running those functions on a workstation, said product marketing manager Sylvie Hurat.

The former Axis Systems, now Verisity's platform division, has created a 3G emulation system that can be accessed by multiple users 24/7. Michael Young, director of product marketing for the platform division, said the new Xtreme Server is targeted at large enterprise customers with multiple teams and projects. "You can serve up to 12 concurrent sessions at the same time regardless of the mode of operation," he said.

For example, groups of designers in different locales can log onto Xtreme Server running at a third location. One group can run a mix of simulation and acceleration while the other runs simulation and emulation.

The system can handle designs of up to 50 million gates at a price of 12 cents per gate. It includes 12GB of memory, or twice as much as Xtreme-II, the previous-generation system.
