Synopsys, Inc. (NASDAQ: SNPS), a world leader in semiconductor design software, today announced that its DesignWare® IP for PCI Express® supports the recently released PCI Express 1.1 specification, which includes several errata updates and improvements to increase the robustness of power management and error handling. The PCI Express 1.1 standard incorporates the industry's combined design experience of the past two years and reflects the strong growth and wide-spread adoption of the PCI Express interface. The PCI Express 1.1 specification is fully backward compatible with the PCI Express 1.0a specification. With DesignWare IP for PCI Express, designers can immediately begin taking advantage of the new version 1.1 features of the PCI Express specification.

"Designers depend on Synopsys, the leading provider of IP for PCI Express, to deliver quality IP for the latest interconnect standards," said Guri Stark, vice president of Marketing, Synopsys Solutions Group. "The quick support of the PCI Express 1.1 release demonstrates Synopsys' commitment to providing industry-leading PCI Express solutions that help enable the rapid adoption of PCI Express."
