Abstract: 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.

Abstract: A method for providing a fill pattern for integrated circuit designs is disclosed. A keepout file having keepout data is generated from a chip design layout file having chip design layout data. The keepout file includes a map of areas of an integrated circuit design where fill patterns cannot be placed. The map of areas from the keepout file is then overlaid with a fill pattern to yield a fill-pattern file. Fill patterns from the fill-pattern file is removed from locations that coincide with locations as defined by the keepout data to yield a final-fill file with crucial fill pattern data. The crucial fill pattern data from the final-fill file is overlaid on the design layout data in the chip design layout file to yield a complete design layout file. Finally, the design rule integrity and logical to physical correspondence of the complete design layout file is verified.
