TransEDA Joins HyperTransport™ Technology Consortium and Introduces HyperTransport Verification Suite

LOS GATOS, Calif. - March 18, 2002 - TransEDA® PLC, the leader in ready-to-use verification solutions for electronic designs, announced that it has joined the HyperTransport™ Technology Consortium. As its first deliverable as a Consortium member, the company will offer the new TransEDA HyperTransport Verification Suite™ consisting of a HyperTransport bus functional model (BFM) and a HyperTransport property library. The HyperTransport Technology Consortium is an active forum of companies developing advanced interconnect technology that is designed to greatly improve performance of a wide range of communications, storage and networking devices.

"With its excellent reputation for high quality models, TransEDA will be a valuable member of the Consortium," said Gabriele Sartori, president of the HyperTransport Technology Consortium. "There has been a significant amount of demand from other members of the Consortium for bus functional models based on the HyperTransport standard. The new products from TransEDA will help companies developing systems with HyperTransport interfaces to greatly speed their verification process."

HyperTransport Bus Functional Model Speeds Complex System Verification
Using TransEDA's self-checking and automated BFM, verification engineers can verify the HyperTransport interface of a design under realistic and concurrent traffic conditions without having to spend months creating and debugging their own models. The HyperTransport BFM is based on the latest HyperTransport I/O Link Specification from the HyperTransport Technology Consortium (version 1.03), and is part of TransEDA's Foundation Models™ system-level verification IP library.

As with all Foundation Models, the HyperTransport BFM is user-configurable. It includes a protocol monitor and can be configured as a fully functional HyperTransport Host Bridge (HTHB) or a single-link device. It can be used as a stand-alone model via the transaction-level application-programming interface (API) for easy integration with existing verification environments. The BFM can also be used with TransEDA's VN-Control™ application-specific test automation software for a complete system-level verification environment, including automatic test generation from a high-level template and automatic results checking for target applications. Future HyperTransport BFM releases will include tunnel, bridges with and without tunnels, and secondary host bridge functionality. The model is compatible with leading hardware description language (HDL) simulators through the Verilog PLI. The intelligent features of the new BFM enable high-volume pseudorandom testing and automatic results checking. See the attached list of product features for further details. "The automatic generation of a high volume of real world traffic, the protocol interface checking and data consistency checking features of our new BFM are of great value to verification engineers," said Scott Winick, director marketing for system verification at TransEDA. "There are no new languages to learn and no complex models or drivers to write. Our HyperTransport Verification Suite enables designers to focus on chip development rather than writing their own models."

HyperTransport Property Library Verifies Protocol Compliance and Coverage
The second component of the HyperTransport Verification Suite is a comprehensive property library describing the HyperTransport specification in terms of both expected and prohibited protocol behaviors. This property library, used with TransEDA's recently announced VN-Property DX™ dynamic property checker, helps to ensure that no HyperTransport operating rules were violated during simulation, and provides detailed protocol coverage metrics and reports. The components of the library can also be used as building blocks to create higher-level properties. More information on dynamic property checking can be found at www.transeda.com/vnpropertydx.

About TransEDA Foundation Models
TransEDA's Foundation Models system-level verification IP library features field-proven processor BFMs, standard bus agents, monitors, and properties for use in existing HDL verification environments or with other TransEDA products. In addition to HyperTransport, the library supports PCI, the Intel Pentium® and Intel Itanium processor families and the Vr5464™ MIPS® processor from NEC®.

Pricing and Availability
The HyperTransport Verification Suite will be available in April 2002. List price for the HyperTransport BFM begins at $20,000 (U.S.) for a one-year subscription license. List price for the HyperTransport Property Library for use with VN-Property DX begins at $15,000 (U.S.) for a one-year subscription license.

About HyperTransport Technology
HyperTransport Technology is a new high-speed, high-performance, point-to-point link for integrated circuits. HyperTransport provides a universal connection that is designed to reduce the number of buses within the system, provides a high-performance link for embedded applications, and enables highly scalable multiprocessing systems. It was developed to enable the chips inside of PCs, networking, and communications devices to communicate with each other up to 48 times faster than with some existing technologies.

About HyperTransport Technology Consortium The HyperTransport Technology Consortium is managed by its members. The consortium promotes the common business interests of providers to the networking, telecommunications, computer and high-performance embedded application through the conduct of a forum for the future development and adoption of the HyperTransport specification.

AMD, API NetWorks, Apple Computers, Broadcom, Cisco Systems, NVIDIA, PMC-Sierra, SGI, Sun Microsystems, and Transmeta are the charter members that comprise the Executive Committee of the HyperTransport Technology Consortium.

Companies interested in the HyperTransport specification are invited to join the consortium. Members of the consortium pay annual dues and receive a royalty-free license to HyperTransport IP, gain access to technical documentation and may attend consortium meetings and events. To become a member, visit the consortium Web site at www.hypertransport.org.
