Abstract:	In this work, we employ gridded model for channel routing and place the terminals which are horizontally aligned. We have developed a two-layer channel router that can eliminate the constraints due to overlap. The proposed approach is suitable for cell/IP-based channel-less circuit with a few channels. Our developed tool can route the nets in nearly linear time achieving to the advantage of time to market, and lead to the area overhead of 6.34% increase in average. The area overhead results from the space insertion, and we also have shown that the proposed algorithm can achieve 100% routing on most ISCASpsila85 benchmarks. In addition, the number of channel tracks can be minimized by our algorithm.
