Abstract
A system for optimizing placement of a plurality of cells located on a surface of a semiconductor chip divided into regions by grid lines is disclosed herein. The system first increases the size associated with each cell by a fixed amount. The system then performs various density equalization routines to all cells, and locates cells having a size greater than a predetermined quantity and fixes those cells. Finally, the system executes a plurality of optimal cell movement routines to crystallize cell placement.
