Tool suite for the rapid development of advanced standard cell libraries employing the connection properties of nets to identify potential pin placements

摘要

A library tool suite supplements conventional design tools to increase the speed, automation and accuracy of creating physical designs for a library of cells to be used in chip designs. The tool suite may include a post operations tool, an audit tool, a custom interface, a setup file and a place and route model preparation utility which interact with the conventional tools and design data to automate and ensure integrity of the physical design process. The tool suite facilitates automatically generating libraries corresponding to an overall cell plan, generating attributes defining strength of connection between possible pin placements within a cell to facilitate routing inter-cell nets through a cell, and auditing cells for errors prior to inclusion in a manufacturing library.
