iVivity Selects Mentor Graphics Ethernet Intellectual Property Family for iDiSX State Machine Architecture

WILSONVILLE, Ore., March 22, 2007 – Mentor Graphics Corporation (Nasdaq: MENT) today announced that iVivity, a leader in I/O and application processors for networking and storage applications, has selected Mentor Graphics’ 10/100/1000 Mbps and 10G Ethernet Intellectual Property (IP) cores for the iVivity iDiSX architecture. Mentor’s industry-leading Ethernet IP family was chosen due to its robust characteristics, including standards-compliance and ease of integration.

The iVivity iDiSX processor is the industry’s only proven hardware state machine architecture that delivers full 10Gbps line rate throughput regardless of packet size with optimized power management providing easy integration and lower costs for next generation Ethernet-networked products, such as servers, switches, storage and networking appliances. iVivity products serve as fundamental building blocks for leading networking technologies, such as voice, video and data networks.

“We chose Mentor Graphics Ethernet IP based on their seamless integration of the IEEE 802.3 standard in the PCS and MAC layers. Mentor’s IP provides us with a relatively small pin count connectivity solution to the physical layer device,” stated Ben Sum, senior staff engineer at iVivity. “Low latency and larger frame size support is another important feature we found with Mentor’s IP, which allows our design to process the frame efficiently in the storage environment.”

The iDiSX hardware-based TCP acceleration provides the highest performing platform for designers to build on, without impacting the host or associated applications. This provides higher levels of throughput with feature-rich applications, critical for today’s LAN/WAN Ethernet networked environments.

“We are enabling leading companies like iVivity to provide better solutions for their customers with our standards-based IP,” stated Bill Martin, Mentor Graphics IP Division general manager. “Ease of integration, standards compliance, technical support and responsiveness to customer needs, are just some of the many benefits in using a qualified IP provider, but ultimately, our IP helped facilitate iVivity’s goal of optimized network performance with minimized impact on system resources.” For more information on Mentor’s Ethernet IP products and product portfolio, go to the company website: www.mentor.com/IP or contact Mentor Graphics local sales representative at 1-800-547-3000.
