San Mateo, California, October 27, 2000 - Prover Technology, the leading provider of commercially packaged proof engines, today announced that Xilinx, the leading innovator of complete programmable logic solutions, has deployed Prover Technology's proof engine Prover Plug-In to ensure the correctness of IP in the Xilinxâ CORE Generator system for the new Virtexä-II FPGA architecture.The deployment of Prover Plug-In allows Xilinx to deliver the highest quality cores, enabling its customers to begin designs for the new Virtex-II architecture before silicon is available.

The CORE Generator system is a component of the Xilinx Foundation ISEä and Alliance Seriesä software and enables the configuration of parameterized cores for Xilinx devices, including the new Virtex-II architecture. The Virtex II architecture was developed for system performance by maximizing bandwidth in I/O, timing, memory, and processing.

Xilinx has developed an in-house verification tool tailored to the Virtex family, which at its heart uses Prover Plug-In. The combination has resulted in a system that automatically establishes the correctness of core implementations produced by the CORE Generator system. The proof engine technology was specifically used to verify Xilinx BaseBLOX components. These building blocks are used heavily in customer designs and in higher level cores, so their correctness is of the utmost importance.

"By using Prover Plug-In when verifying our IP for the Virtex-II architecture, we were able to complement our existing verification flow with formal verification to find and fix additional bugs over and above those usually found by traditional simulation, " said Bill Carter, VP and chief technology officer of Xilinx. "We chose Prover Plug-In because it is based on SAT technology which allows much larger circuits to be verified compared to conventional formal verification technologies such as BDD."

"Xilinx is one of the world leaders when it comes to advanced, integrated system functions and a pioneer in adopting formal verificaton solutions for programmable hardware, says Arne Boralv, President US Operations, Prover Technology. "In this joint project, we provided the proof engine and the know-how, and Xilinx provided the application-specific software in a collaboration that underscored the strengths of each company and delivered far ahead of expectations."
