A Model and Storage Technique for Versions of VLSI CAD Objects
VLSI CAD ojbects involve several representations. For each representation, designers experiment with multiple versions. In this paper, we first outline a logical framework that captures the dimensionalities in CAD objects and their versions, and then outline a storage technique that balances the requirements for reducing storage redundancy and fast access to different versions of the same design object.
