CATC's PCI Express Analyzer First to Support Industry Standards

2/19/2003 - Computer Access Technology Corporation(TM) (CATC(TM)) (Nasdaq: CATZ), a communications protocol expert company and a leading provider of advanced verification systems and connectivity products for digital communications standards, announced the CATC PETracer(TM), a powerful design verification system that provides robust PCI Express(TM) data traffic capture, intuitive display and expert analysis. PETracer marks CATC's entry into the PCI Express market, with the first protocol analyzer system to support the newly released standard. PETracer non-intrusively monitors a single 2.5Gbps dual simplex PCI Express link, triggers on specific events and presents the recorded traffic in the highly intuitive CATC Trace(TM) expert software. The analyzer enables IP, semiconductor, switch, software and system developers as well as add-in card vendors to quickly identify protocol violations and reduce debugging time.

Developers can use the PETracer to easily capture and decode PCI Express Transaction Layer Packets (TLPs), Data Link Layer Packets (DLLPs), and low-level link traffic, including Training Sequences and Skip Ordered-sets. Some of the errors detected include: 8b/10b errors, such as invalid symbols and incorrect running disparity; CRC errors; idle data errors; and EDB (End-of-Packet Bad) errors. PETracer also provides a detailed display of split transactions on the PCI Express link, correlating requests transmitted from one PCI Express endpoint with completions received from the endpoint at the opposite end of the link.

"PCI Express architecture emerged as a key I/O technology in 2002 and PCI-SIG has seen new product development underway this year. Validation testing is an important piece of the product design cycle and PCI-SIG is excited to see support from CATC," said Tony Pierce, chairman of the PCI-SIG. "Technology enablement is a top focus for our organization in 2003."

"CATC is committed to deliver expert analysis and verification systems for existing and emerging communications protocols, as we have done for more than 10 years. We are very excited about the PCI Express standard and are working very closely with the PCI-SIG community to accelerate new product introduction," said Dan Wilnai, president and CEO of CATC. "The PETracer is an essential tool to accelerate product development and assure interoperability and protocol compliance."

The PETracer fits into the CATC Universal Protocol Analysis System(TM) (UPAS(TM)) 2500H, allowing rapid development and testing of products and enabling engineers to quickly move from protocol to protocol. PETracer also leverages the intuitive and powerful CATC Trace expert analysis software, which displays communications traffic in searchable, easy-to-use, color-coded fields with detailed traffic and error summary reports.

Pricing and Availability
CATC is accepting orders for the PETracer for delivery beginning in March 2003. For pricing or additional information, please contact CATC or its worldwide network of distribution partners.
