Abstract
Due to the increase of operation frequency in recent LSI systems, signal propagation delays are required to achieve specifications with very high accuracy. In order to achieve the severe requirements, signal propagation delay is taken into account in the routing design of PCB (Printed Circuit Board). In the routing design of PCB, the controllability of wire length is often focused on since it enables us to control the routing delay. In this paper, we propose CAFE router which obtains routes of multiple nets with target wire lengths for single layer routing grid with obstacles. CAFE router extends the route of each net from a terminal to the other terminal greedily so that the wire length of the net approaches its target wire length. Experiments show that CAFE router obtains the routes of nets with small length error in short time.
