Abstract

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 pin to the other pin 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.
