NextIO Selects Denali PureSpec for PCI Express Design Verification

Signs Denali as Exclusive Verification IP Provider

PALO ALTO, Calif., July 22, 2005 -- Denali and NextIO, Inc., a chip developer for enterprise-class computer servers, today announced an agreement that provides NextIO with Denali's PureSpec™ verification intellectual property (IP) for functional verification of the PCI Express interface of its enterprise server chips.

NextIO engineers are using PureSpec at the pre-silicon stage of design to simulate interactions through the PCI Express interface in order to verify the correct and optimal operation of the chip's design.

"Denali's PureSpec is the most trusted solution for verifying PCI Express designs," notes Chris Pettey, CTO of NextIO. "We have a veteran design team with extensive experience in the server market and they asked for Denali's PureSpec. In addition to its superior technology for exposing design issues, the widespread use of PureSpec gives us the added confidence in verifying interoperability with other PCI Express designs."

Denali's PureSpec verification IP includes a configurable bus functional model (BFM) integrated with thousands of assertions that enable NextIO to verify its PCI Express interface for compliance with the specification and interoperability with other PCI Express devices. Used by more than 60 companies worldwide, PureSpec is the most widely used verification IP product for simulating and verifying PCI Express design interfaces. "Interface verification is playing an increasingly critical role in advanced chip development flows such as NextIO's," adds David Lin, Denali's vice president of Product Marketing at Denali. "PureSpec is a well-architected product that reduces risk and delivers real verification productivity. It's nice to see that we hit the mark with a leading-edge design effort, and we are pleased to be a part of NextIO's design verification flow."
