Denali Deploys IP for PCI Express 2.0 Products to more than 80 Customers

PALO ALTO, Calif., Jan. 24 -- Denali Software, the world leader in Electronic Design Automation (EDA) and Intellectual Property (IP) products for standard semiconductor chip interfaces, today announced that its PureSpec(TM) product is the first verification IP to support the evolving 2.0 version (Gen II) of the PCI Express(TM) specification.

More than 80 customers currently using Denali's PureSpec verification IP for PCI Express version 1.1 now have access to PureSpec for the latest (0.7) version of the Gen II specification. PureSpec also supports the most recent update to the PIPE specification for Gen II, which enables the development of functionally equivalent PHY interfaces.

Denali's PureSpec(TM) verification IP software for PCI Express is the most widely used solution for verifying functionality, compliance and interoperability of PCI Express designs at the pre-silicon stage of chip or IP core development. Previously announced customers using PureSpec for PCI Express development include: Agere Systems, Atheros Communications, NVIDIA Corporation, Rambus, Sun Microsystems, and Unisys.

"Our PureSpec product that supports PCI Express Gen II has been deployed with key customers for several months now," says David Lin, vice president of product marketing for Denali. "As the leader in verification solutions for PCI Express technology, our customers rely upon Denali to deliver early access to high-quality verification solutions for PCI Express designs. Our PureSpec product is in sync with the latest revisions from the PCI-SIG, and we continue to track the specification and provide our customers with updates as they occur."

PureSpec supports both PCI Express version 1.1 and Gen II revision 0.7. It includes a configurable bus functional model (BFM), protocol monitor, and complete assertion library for all components in the topology, including the root complex, switch, endpoint and PCIe to PCI bridge. Generic devices conforming to the specification can also be emulated. Composite configurations by port, function or virtual channel are also supported. In addition to the comprehensive coverage of the PCI Express version 1.1 specification, PureSpec feature enhancements for PCI Express Gen II include Access Control Service (ACS), Function Level Reset (FLR), speed negotiation and the new PIPE specification.

Denali is an active member of the PCI Special Interest Group (PCI-SIG) electrical working group (EWG) which is specifically chartered with defining the PCI Express Gen II specification. While maintaining backward compatibility with the 1.1 version of the specification, the Gen II specification provides numerous improvements designed to address increased bandwidth and networking and embedded and computer applications.
