Abstract

This paper describes two routers for automatic routing of printed wiring boards (PWBs) used in very high-speed, very large-scale computers. One router named specified-delay router is for touting wires that must provide an exact specified delay time. The other router named concurrent router is able to route the tens of thousands of wires required for high-density PWBs very fast with a high success ratio and high quality. These two routers were used to develop the new Fujitsu M-780 computer model group. They helped to reduce development time and to improve computer performance.
