Abstract
A system for computing an affinity for relocating a cell from a location on a surface of a semiconductor chip is disclosed herein. Each cell may be associated with a net connecting a plurality of cells. The system first partitions the surface into a number of regions and computes capacities of lines dividing the regions and number of nets crossing the lines. The system then calculates penalties based on the number of net crossings and the capacities of lines and determines the total affinity based on relative improvements for lines crossed by the nets.
