Mentor Graphics and Denali Collaborate to Deliver High-Quality Intellectual Property for PCI Express and Advanced Switching Interfaces Mentor's PCI Express and Advanced Switching Cores Verified with Denali PureSpec PALO ALTO, Calif., Aug. 30 /PRNewswire/ -- Denali Software Inc. and Mentor Graphics Corporation (NASDAQ:MENT) today announced a collaborative effort to ensure high quality and ease of deployment for the Mentor Graphics(R) PCI Express intellectual property (IP) cores. Mentor Graphics will use Denali's PureSpec verification IP product to confirm its PCI Express IP core is compliant with the PCI Express and Advanced Switching Interconnect (ASI) interface standards, and interoperable with other system designs. Through this effort, Mentor will provide its customers with the highest possible quality IP, while lowering the cost of deployment and integration. "Denali is a leader in verification solutions for PCI Express and Advanced Switching designs and we are pleased to collaborate with them on this effort," said Michael Kaskowitz, general manager, Intellectual Property Division, Mentor Graphics. "Compliance and interoperability are key requirements for success and this collaboration will move us a long way towards this goal. Working with Denali, we are able to increase the quality and efficiency of our PCI Express and ASI capable IP solutions, while strengthening the Denali solution by sharing our knowledge and experience as a leading IP provider." Adds Denali's Chief Technology Officer Mark Gogolewski: "Mentor Graphics PCI Express IP provides an excellent foundation for Advanced Switching solutions. Our role is to provide our customers with the highest quality verification IP to enable fast efficient development of these critical interfaces. A key part of this enablement is to work with leaders like Mentor to ensure that our mutual customers can seamlessly integrate and verify the Mentor IP in the customers design environment."
