Design data management in a CAD framework environment

ABSTRACT

The design data management system is a crucial component in an IC CAD framework environment as the design involves large volume of data in diversified formats. This article identifies requirements for such a system and presents the approaches that a design framework utilizes to support these requirements. Several aspects, including a library model, version control, configuration management, access control, and history tracking, are explored and feasible solutions are proposed. The system is currently under development and will be released in the next generation of the Cadence design framework.
