Design system for vlsi chips arranged on a carrier and module thus designed

Abstract From the Canadian patent

A system design for VLSI chips arranged on a carrier and the module thus designed is described. In a top-down design system synoptically and simultaneously an electrical circuitry is optimized by designing synoptically the chips and the chip carrier. The overall logic is divided in partitions which fit on chips. A chip placement on the carrier is performed considering minimum overall connection length and providing preferably parallel connection. Input/Output contacts are assigned on chips vis-a-vis each other when they correspond. They are connected by parallel lines. The design of the several chips is done from outside to inside starting, with the assigned I/O contacts. Overall in …
