Denali's PureSpec Product Licensed by Sun Microsystems for PCI Express Design Verification

PALO ALTO, Calif., March 30, 2004 --Denali Software, Inc., the leading provider of electronic design automation (EDA) tools and intellectual property (IP) for chip interface design and verification, today announced that Sun Microsystems, Inc. has licensed Denali's PCI Express verification tools for the development of the PCI Express interfaces in its next-generation server chips. Sun engineers are using Denali's PureSpec(TM) verification IP to model, simulate, and verify the interface between Sun's chips and other PCI Express compliant devices. By using Denali's PureSpec solution, Sun engineers can expose potential interoperability bugs early in the development cycle before the designs are implemented in silicon, saving valuable development time and resulting in faster time-to-market with a higher quality end product.

"Denali is at the forefront of developing tools and technology for interface modeling and interoperability verification," said Paul Gingras, Hardware Verification Manager at Sun Microsystems. "Verifying PCI Express interface on our next-generation server chips is a critical task for us. Using Denali's PureSpec product in our verification flow gives us added confidence that our designs are compliant with the PCI Express standard, and interoperable with other PCI Express implementations."

"Our role is to provide industry leaders such as Sun with tools for designing and verifying chips that incorporate the PCI Express standard," said David Lin, vice president of applications engineering at Denali. "A key part of this enablement is ensuring that these chip designs are interoperable with other PCI Express devices. Widespread use of the PureSpec product in the industry will assist our customers to coordinate verification efforts and achieve pre-silicon interoperability verification. We are pleased to be working with Sun and look forward to their successful launch of PCI Express enabled server chips."

PCI Express technology is a new I/O standard targeted to provide local connectivity across desktop, enterprise and communications platforms. PCI Express is a key enabler of enterprise interconnect innovations anticipated across storage, networking, clustering and workstations. Next-generation servers, utilizing PCI Express technology, will offer powerful and cost- effective computing platforms, scalable hardware building blocks, market- tested best-of-breed solutions, and enterprise-class reliability, availability, serviceability and manageability.

About PureSpec
PureSpec is a verification IP product used by chip designers to simulate, and verify PCI Express design interfaces. PureSpec models all devices in the PCI Express topology, including the root complex, switch, endpoint, and PCI Express to PCI bridge. Within PureSpec, all protocol layers (physical, data link, transaction) of the PCI Express specification are completely modeled and can be simulated concurrently or independently. The product contains thousands of assertions that are monitored during simulation to ensure compliance with the PCI Express specification, and interoperability with other PCI Express devices. The PureSpec product is built on the proven product architecture of Denali's MMAV product, which has been used to verify complex memory interfaces for thousands of successful designs, and provides seamless integrations to all popular EDA tools and verification languages. Proven product platform, dedicated customer support, and unmatched EDA modeling and verification expertise make PureSpec the best-in-class verification IP solution for PCI Express designs. The PureSpec product is available now for customer evaluation at: www.denali.com/purespec.
