Denali Announces Availability of PCI Express I/O Virtualization Solutions

PALO ALTO, Calif., May 16, 2007 —Denali Software, Inc., a world-leading provider of electronic design automation (EDA) software and intellectual property (IP), today announced the availability of design cores and verification IP which support the preliminary I/O virtualization (IOV) specifications from the PCI-SIG. IOV is a key technology that enables systems to simultaneously share PCI Express (PCIe) resources within multi-CPU systems, or across multiple operating systems. Vendors are now architecting data centers and large storage environments that use IOV technology to increase performance and reduce overall power and system costs. Denali's Databahn™ PCIe IOV cores and PureSpec™ PCIe verification IP products are now being used by developers to accelerate the design and verification of these systems, and speed overall deployment of PCI Express IOV technology.

"With the growth of computational power and the number of servers in storage environments, technologies to support current and future requirement for high-speed connectivity, such as IOV, becomes a critical requirement," remarks Jag Bolaria, senior analyst at The Linley Group. "Denali is paving the way with its IP solutions for PCI Express IO Virtualization technologies."

Denali's Databahn PCIe IOV cores and PureSpec PCIe verification IP products provide full support of the Address Translation Service specification, Single-Root I/O Virtualization specification, including physical and virtual function (VF) configuration spaces, VF Alternate Routing-ID, and Functional Level Reset (FLR) capabilities. These features will be highlighted at the PCI-SIG Developers' Conference, May 21-22 in San Jose, CA, by Denali's systems architect, Anujan Varma. Mr. Varma is scheduled to present two papers on advanced PCI Express technologies, including "LTSSM Implementation at 5Gb/s and Beyond" and "Single Root IOV Endpoint Implementation," which is based on an actual reference implementation of the IOV specification.

Additional info about the PCI-SIG IOV specification can be located at: http://www.pcisig.com/specifications/iov/.

"Our pre-silicon PCIe virtualization solutions represent significant cost and time-saving potential without jeopardizing our customers' high performance requirements," remarks David Lin, vice president of product marketing for Denali. "Our customers depend on high-quality design and verification IP solutions that are inline with the developing trends with the PCI Express technology."
