ABSTRACT:
The invention provides a method and system for automated circuit design case management. A computer system maintains a set of cases for circuit design, in which each case comprises a set of files, in one or more directories, representing the circuit design. For example, each case may comprise a circuit schematic, a symbolic representation for a circuit element, a set of timing information, or a wiring diagram. The system provides a set of tools for automated management, manipulation, and verification of cases. The system provides a technique by which a designer or other user may create a case in which the program maintains assertions regarding the state of the circuit, the mode of operation, or the purpose of analysis for that case. The system provides a technique by which a designer or other user may modify a first case, or create a second case modeled on the first case, in which a first subset of the files for each case is invariant and a second subset of the files differ between the two cases. The system provides links provided between the first case and the second case for those files which are invariant, so as to provide for simultaneous modification of multiple cases and to provide for simultaneous analysis of multiple cases.
