A hierarchical floorplanning method is presented in which it is possible to determine simultaneously a floorplan and detailed global routes which directly correspond to switchboxes and channels. In this method, since the precise estimation of congestion of channels and switchboxes is possible, no extremely congested channels and switchboxes are created. Experimental results show that the method can produce an optimal floorplan in terms of congestion
