MODULAR CELL PLACEMENT SYSTEM WITH DISPERSION-DRIVEN LEVELIZING SYSTEM

摘要

A system for optimizing the density of cells located on a surface of a semiconductor chip divided into a plurality of rectangular regions is provided herein. The corners of these regions define nodes. The system comprises computing an average local cell density for regions adjacent to each node and deforming these regions by relocating nodes to positions that minimize a cost function associated with the densities of the new deformed regions bordering the relocated nodes.
