MOBILE, Ala.--(BUSINESS WIRE)--Nov. 5, 2003

Accelerated Technology(R), the Embedded Systems Division of Mentor Graphics Corporation (Nasdaq:MENT), today announced that the Nucleus(R) NET TCP/IP protocol stack and networking components have been tested and validated by the Automated Network Validation Library (ANVL(TM)), a data network testing solution from Ixia (Nasdaq:XXIA). This intensive validation confirms that the Nucleus networking software fully conforms to the official Internet networking standards which are maintained and administered by the Internet Engineering Task Force (IETF).

Ixia's ANVL is an automated testing package that validates the protocol implementations and operational robustness of networking devices. By incorporating ANVL into the development and test processes, users save valuable time and money because they do not have to spend development time writing custom conformance tests.

Accelerated Technology's network protocol offering is among the broadest in the embedded industry. It includes the Nucleus NET TCP/IP protocol stack, Internet applications such as a Web server and e-mail software, and network management products such as the Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON). Some of the recent additions to the networking suite are 802.11b support and Internet Protocol version 6 (IPv6). With so many networking protocols, it is important to have the ANVL testing tool to verify conformance with industry specifications. To date, both the Nucleus NET protocol stack and the Nucleus IPv6 software have been tested and validated with Ixia's ANVL.

Since the Nucleus software is often used to build mission critical applications, it is important that the Nucleus software adheres to the highest quality standards. This is a responsibility that Accelerated Technology takes seriously and ultimately led the company to use ANVL. The ANVL testing suite helps ensure that the Nucleus software is adequately tested and that the Nucleus software customers receive the highest quality products possible.

"Part of the success of the Nucleus real-time operating system has been due to our commitment to both providing a complete networking product suite and to producing quality products. Ixia's ANVL reinforces our ability to execute on both of those commitments, enabling us to deliver high-quality networking protocols to market quickly," said Robert Day, director of marketing, Mentor Graphics Embedded Systems Division.

"Ixia continues to be committed to our ANVL conformance validation test suite because conformance testing has demonstrated its ability to speed customers' time to market resulting in substantial cost savings," said Alan Amrod, vice president of Marketing for Ixia. "We are delighted to have played a critical role in Mentor Graphics development and testing stages as it expands its offerings into the networking market."

The Nucleus NET networking stack, a scalable embedded TCP/IP protocol stack, is the basis for Accelerated Technology's networking suite. The Nucleus NET stack, unlike other protocol stacks in the embedded industry, was built from the ground up for the real-time embedded market. In addition, critical portions of the stack have been optimized, resulting in a stack that is among the smallest and fastest on the market. The basic protocols for the Nucleus NET protocol stack include: TCP, UDP, IP, ICMP, IGMP, ARP, RARP, DHCP, BOOTP and DNS.
