Abstract:
1. A computer system that is queried to determine electrical circuit characteristics of data stored in a netlist database comprising: a computer-readable electronic storage medium; a computer that reads and writes data from and to said electronic storage medium; parsed netlist data that has been parsed from a netlist text file that is representative of an electrical circuit, said netlist text file being created by an electrical schematic capture software tool, said electrical schematic capture software tool deriving said netlist text file from an electrical circuit schematic representative of said electrical circuit, and said parsed netlist data being representative of device data, device attribute data, macro data, macro attribute data, connection data, and connection attribute data of said electrical circuit; an object oriented database structure that stores said parsed netlist data on said electronic storage medium comprising objects and object holding tables logically organized to represent said device data, said device attribute data, said macro data, said macro attribute data, said connection data, and said connection attribute data contained in said parsed netlist data; and netlist database access subroutines that permit an external software program to read and update said parsed netlist data contained in said netlist database in order to programmatically analyze said electrical circuit characteristics to locate topological circuit problems.
