Virtutech Simics Used For Development Of Switchcore Xpeedium3 Switch Chip Before Silicon Availability

Simics Simulation Environment Enables Development of Software Drivers and Management Packages to Run in Parallel with Development of Silicon and Accelerate Time to Market

SAN JOSE, Calif. — May 15, 2006 — Virtutech, Inc., the leading provider of simulation-based solutions for software development and test, today announced that SwitchCore, a developer of integrated switching devices for Internet and data communications, has selected Simics for use in software development and testing of its next-generation Xpeedium3 switch chip before silicon availability. Simics allows software development to proceed concurrently with the design of the integrated circuits, thus accelerating time-to-market

In an effort to accelerate the time-to-market for its next-generation switch chips, SwitchCore needed to provide a solid software simulation environment — before silicon availability — to enable development of software drivers and management packages to run in parallel with the development of the silicon. By selecting Virtutech Simics, SwitchCore not only eliminates the risks involved with developing the simulator in-house, but enables its developers to scale simulation to multiple-chip and multiple-CPU configurations on a single desktop. Simics provides a revolutionary platform to enable easy connection and simulated traffic generators, as well as the ability to be connected to the real network through network interface cards (NICs). SwitchCore’s customers will also leverage the simulation model to test and evaluate SwitchCore’s chips for their own products.

“We are very happy to partner with Virtutech for our simulator,” said Peter Ygberg, vice president of SwitchCore product management. “Simics will not only accelerate our own development, it will also enable us to share our full software and our functional model with our early access customers.”

“The selection of Simics to support the advancement of leading data switching technology underscores the benefits of full-system simulation,” said John Lambert, president and CEO of Virtutech.  “This key customer win serves as further proof of the value of Simics’ deterministic capability in the development process.”
