Abstract

The invention provides a method, system, and program product for diagnosing an integrated circuit. In particular, the invention captures one or more images for each relevant circuit layer of the integrated circuit. Based on the image(s), a component netlist is generated. Further, a logic netlist is generated by applying hierarchical composition rules to the component netlist. The component netlist and/or logic netlist can be compared to a reference netlist to diagnose the integrated circuit. The invention can further generate a schematic based on the component netlist or logic netlist in which components are arranged according to port, power, and/or component pin connection information determined from the netlist. Further, the schematic can be displayed in a manner that wiring connections are selectively displayed to assist a user in intelligently arranging the circuit components.
