Synopsys and Artisan Announce Collaboration to Validate Interoperable PCI Express Solution

Two Industry-Leading IP Providers Work Together to Accelerate Adoption of the New High-Speed PCI Express Architecture

SAN JOSE, CA, Intel Developer Forum - September 15, 2003 -Synopsys, Inc. (Nasdaq: SNPS), the world leader in semiconductor design software, and Artisan Components®, Inc., (Nasdaq:ARTI), a leading provider of physical intellectual property (IP), today announced a collaboration to develop a hardware platform that validates the interoperability of their PCI Express™ IP solutions. The platform conforms to the PIPE (PHY Interface for PCI Express) standard and helps to assure seamless operation and lower-risk implementation for chip developers. Synopsys and Artisan plan to develop a mother/daughterboard platform utilizing Synopsys' DesignWare® PCI Express Endpoint Controller Core and Artisan's PCI Express PHY IP. Synopsys and Artisan plan to present the solution at the PCI Express Interoperability Workshop in the fourth quarter of 2003.

"High-speed serial interface PHYs are complex circuits that must be verified both in silicon and in a system context," states Callan Carpenter, vice president and general manager, Artisan Analog/Mixed Signal Business Unit. "By working together to rigorously establish interoperability between our respective IP, Artisan and Synopsys are helping to reduce the integration risk that confronts every system-on-chip design."

"As the market leader in connectivity IP, Synopsys works with leading PHY suppliers like Artisan to validate interoperability," said Guri Stark, vice president of marketing, Synopsys Solutions Group. "This reduces the risk for designers and gives them the confidence to use our joint solutions in their designs, enabling them to bring products to market more quickly."

The platform demonstration will consist of two boards: a Synopsys-developed motherboard including FPGAs to house the Synopsys Endpoint Controller with driver software, and a daughterboard consisting of Artisan's PHY silicon. The interface between the two boards will adhere to industry-standard PIPE specifications. Synopsys' motherboard will include three critical protocol layers - the logical PHY layer, the data link layer and the transaction layer. Artisan's daughterboard will include a complete serial link including mux/demux, 8b/10b encode/decode, elastic buffer and clock recovery circuitry that will be compliant with the PCI Express Base 1.0a Specification. Testability features for the Artisan daughterboard include built-in self-test (BIST), serial and parallel loopbacks, IDDQ (power down) and pseudo random bit sequence (PRBS).

The Synopsys DesignWare PCI Express Endpoint Controller Core features configurability from one to eight channels, low gate count, and timing closure to a 0.18-micron generic process. This architecture not only supports all of the features required for a PCI Express Endpoint solution, but it is also optimized for layout and performance and implements "enhanced" transaction layer features.

Artisan's PCI Express 2.5Gb/s PHY core provides high performance, flexibility, low power consumption, and extensive testability within a small physical size. The PCI Express is a modular design that allows for one to 32-lane configurations to enable a broad range of computing and communication applications, emphasizing performance, cost and scalability.
