SYSTEM AND METHOD FOR SCOPING GLOBAL NETS IN A HIERARCHICAL NETLIST

A method and device for scoping nets from a schematic in a hierarchical netlist. The device is a complementary subsystem to a hierarchical netlister software package. The device allows instances or subcircuits in a schematic to systematically reassign (i.e., scope) local nets which represent global nets to other local nets so that the use of such nets does not affect usage of the global nets elsewhere in the circuit. The device tracks all global nets and maps the corresponding scoped nets to their net identifiers. Then, as the netlister creates the hierarchical netlist, the device replaces the global net's net identifier with the correct net identifier of the corresponding scoped net.
