The Integration of an Advanced Gate Array Router into a Fully Automated Design System

This paper describes the incorporation of an advanced software product into the framework of an existing automated design system. A discussion of the merits and challenges of this undertaking is included. The merits of the MERLYN-G gate array router will be covered in detail, along with the algorithms which contribute to making it a powerful semicustom tool. The RCA design system and its individual software parts will be briefly described to give the reader a better understanding of the advantages of this system. This description will underscore the reasons for taking the necessary steps to assure a successful integration of the entire system. Other topics discussed include CAD databases, IC layout, and software engineering techniques in design automation.
