Abstract :
A floorplanning system was implemented that is based on circuit partitioning and incorporates hierarchical global wiring. Besides unifying several existing ideas in floorplanning, the system introduces the following components: (1) a novel and more accurate estimate of wiring area during the floorplan sizing process and (2) a systematic optimization procedure during the selection of suitable floorplan patterns in the top-down phase that integrates floorplanning and hierarchical wiring. Experiments with the system prove the feasibility of the approach.<>
