Abstract

A system for computing an affinity for relocating a cell on a surface of a semiconductor chip is disclosed herein. The cell is located within a region and belongs to a net of cells. The system initially computes a weight associated with all cells in the net. The sytem then sums the weights of all cells in the net containing the cell for all cells located inside the region and at positions greater than and less than edges of the region and computes the affinity for moving the cell to points on the surface greater than, equal to, and less than the current position of the cell based on the weight sums from said summing function. The computing function further comprises combining the affinities determined based on weight sums with other affinities. The summing function further comprises computing a relationship between the amount of rows and columns of regions on the semiconductor chip surface, and the affinity computation function comprises combining the relationship with the weight sums.
