A history approach of automatic relationships establishment for VLSI design database

摘要

A data management paradigm that incrementally and transparently constructs the relationship among VLSI design objects is proposed. This paradigm is based on a design history model and the specifications of CAD-tool execution semantics. Based on this paradigm, algorithms are developed to automatically establish interobject relationships as a side effect of CAD-tool execution. This paradigm represents a vastly different approach in that it exploits history information, as well as domain knowledge, to deduce useful metadata for data management.
