Abstract :
A design data manager is emerging as an important component of an integrated CAD system. The authors present a semantic data model and an architecture for VLSI/CAD databases. The data model provides mechanisms to represent the design entities the relationships among them in a unified way. A key feature of the system architecture is that it exploits design hierarchy to provide high performance. A data manager based on this model has been implemented and used by a set of diverse applications. In conjunction with efficient data flow, the data manager can serve to improve software productivity.<>
