A distributed engineering database management system for IC design

Abstract

Describes a distributed engineering database subsystem (DDB) which is an integral part of the framework in the PANDA IC-CAD system. DDB provides a simple but efficient method for organizing the IC design data in a distributed environment. With version management and concurrency control services, DDB supports the iterative, tentative and collaborative nature of the design process. A database schema based on the concept of object and how it is used as the foundation for tool integration are also discussed.<>
