ADVANCED SUPERCOMPUTER ARCHITECTURE The Zycad LightSpeed simulation server implements an architecture geared to deliver supercomputer-level performance for simulation of high- end electronic designs. The architecture utilizes: * Massively parallel multiprocessors, in configurations ranging from 64 to 4,096 processors. * On-chip memory for fast processing by reducing off-chip memory accesses. * Hierarchical communications architecture for high-bandwidth communications between processors. * Intelligent partitioning of workloads across the processors. PRICING AND AVAILABILITY Beta shipments of LightSpeed will begin in June 1996. Pricing for typically configured systems is in the $200,000 to $1 million range. UPGRADE PROGRAM SLATED FOR CURRENT ZYCAD CUSTOMERS To ensure its customers' investment in Zycad systems, Zycad will implement an aggressive upgrade program which will enable current and new users of its existing XP and Paradigm XP simulation systems to cost-effectively migrate to LightSpeed simulation servers.
