Paper Abstract

A tapeout system has been developed for a production environment that is extremely high quality and executes quickly for good cycle time performance. The system automatically performs each step of the tapeout task from layer generation on the front-end to final paperwork generation on the back-end. It was designed to reduce human interaction to a minimal level and to be fast, flexible, and easy to use. Several custom GUI windows provide the means of performing data entry and PERL programs link sequential software tasks together. For special needs, any of the individual steps in the tapeout flow can be interrupted and the defaults can be overwritten. Testchips are managed well with the system and show the greatest cycle time benefit ofthe automation. The tapeout system developed at Conexant and described here represents the culmination of nearly one full year of development work plus another two years of subsequent improvements. It has been in full production use at two different sites for more than two years.
