Manukyan Abstract We present new channel routing algorithms that consider the characteristic of net crossings. The routing strategy is based on parallel bubble sorting technique. Non- Manhattan wires as well as overlapping wires are introduced. Preliminary results show that a class of channel routing problems can be routed in height less than the Manhattan density.
