Advanced modular cell placement system with density driven capacity penalty system

摘要

A system for ascertaining the penalty associated with relocating a cell located on a surface of a semiconductor chip to an alternate location is disclosed herein. The system comprises a region capacity calculator for determining a capacity of cells which will fit in the current region, a height capacity calculator for determining the sum of heights for all cells located in each region, a basic penalty calculator which computes a basic penalty associated with relocating the cell to another location based on the capacity and heights of cells for the current region and the capacity and heights of cells in the proposed region, and a total penalty calculator for computing the total penalty associated with the basic penalty, penalties associated with multiple regions, and cell capacity for the current cell.
