We present an improved data model that reflects the whole VLSI design process including bottom-up and top-down design phases. The kernel of the model is a static version concept that describes the convergence of a design. The design history which makes the semantics of most other version concepts, is modeled explicitly by additional object classes (entities types) but not by the version graph itself. Top-down steps are modeled by splitting a design object into requirements and realizations. The composition hierarchy is expressed by a simple but powerful configuration method. Design data of iterative refinement processes are managed efficiently by storing incremental data only.
