The Spirit of in-house CAD Achieved by the Legend of Master "Prof. Goto" and his Apprentices

Abstract

In this paper, a legend story to develop CAD algorithms and CAD/EDA tools for NEC's in-house use is described. About 30 years ago, since there are few commercial CAD tools, ICT vendors had to develop their own CAD tools to enhance the performance of their systems in a short time. Prof. Goto developed several important algorithms for CAD tools and managed to develop many excellent in-house CAD tools. The tools made by him and his apprentices have designed many VLSI/ASIC for NEC's innovative computers and communication systems to enrich our daily lives.
