Design management based on design traces

VOV is an automatic manager for VLSI design. It is based on the idea that CAD tools can leave a trace of their execution. The trace is represented as a bipartite directed and acyclic graph, in which the nodes represent either design data or CAD transactions. By managing and analyzing the traces, VOV offers a wide variety of services related to design management, such as coordination of team design, automatic execution of CAD transactions, and capture of design history and data dependencies. All of these services are provided in a nonintrusive fashion. VOV has the notion of measurement on the design data, an ingredient which is necessary to provide even more services: tracking of design specifications, validation of design data, and design estimation.<>
