Advanced modular cell placement system with iterative one dimensional preplacement optimization

摘要

A system for providing an optimal preplacement of cells on a bounded surface of a semiconductor chip is disclosed herein. A percentage of the cells have predetermined interconnections with other cells. The system initially locates the cells on said surface, then computes coordinates for interconnected cells, determines a weight associated with each cell, and calculates a new cell coordinate for each cell based on the coordinates and weights from said determining step.
