WILSONVILLE, Ore., June 25, 2008 – Mentor Graphics Corp. (Nasdaq: MENT), the leader in high-performance system verification solutions, today announced its high-performance platform to accelerate the verification of PCI Express products. This new platform enables designers to test their complete system, including PCI Express I/O’s, as well as employ real-world stimulus early in the development cycle – reducing the total system verification process from weeks to hours. The platform consists of the Veloce® family of hardware-assisted verification products and the iSolve^TM PCI Express product, which provides a cost-effective and efficient solution, delivering a dynamic and accurate PCI Express verification environment.

Increased bandwidth and performance requirements of modern PC’s and servers, especially those involving high-speed graphics, have meant that PCI Express has become an industry standard, with PCI Express motherboards widespread, and associated peripherals, such as gigabit Ethernet cards and RAID controllers, very popular. With such a prevalence of new products for PCI Express applications, the need for a solution that allows the verification of these products and applications has become more critical and are in high demand.
