Synopsys, Inc. (NASDAQ: SNPS), a world leader in semiconductor design software, today announced that its portfolio of DesignWare® digital controller IP for PCI Express™ is the first to support the evolving 2.0 version (Gen II) of the PCI Express specification. The portfolio includes Endpoint, Root Complex, Switch, Bridge and Dual Mode Cores. While maintaining backward compatibility with the 1.1 version of the specification, the Gen II specification provides several improvements, including an increase to 5 gigabits per second data rate to address the industry's need for increased bandwidth in networking, embedded and computer applications. Synopsys, an active member of the PCI Special Interest Group (PCI-SIG), currently supports the latest (0.7) revision of the Gen II specification and will deliver updates to track the specification as it evolves. This early availability enables companies to begin product development immediately and help deliver compliant products close to the release of the final Gen II specification.

"We chose the DesignWare IP for PCI Express because of Synopsys' aggressive support for the 2.0 standard, their track record of delivering quality IP, and their excellent customer service," said George Hopkins, director of Engineering at SGI. "We have been working with Synopsys' DesignWare IP for PCI Express 2.0 since the 0.3 version of the specification, which has enabled us to immediately integrate new features into products under development. This helps us ensure that we meet our customers' demand for products requiring ever-increasing bandwidth."

"As the leader in PCI Express IP, we understand the importance of making Gen II available to our customers as soon as possible. For this reason, we are releasing the cores early, before the specification is finalized," said Guri Stark, vice president of Marketing, Solutions Group at Synopsys. "Early support for PCI Express 2.0 addresses our customers' time-to-market and reinforces Synopsys' commitment to supporting emerging standards that impact our customers' design needs and critical market windows."

Availability

The DesignWare digital controller cores for PCI Express IP 2.0 are available now for early adopters. The DesignWare Verification IP for PCI Express 2.0 is scheduled for general availability in Q1 of calendar 2006.
