  • Method of recovering a gate-level netlist from a transistor-level
    Patent number: 6190433
    Abstract: The present invention is a method of recovering a gate-level netlist from a transistor-level netlist by functionally describing each gate to be recovered using a first transistor model; generating a signature for each gate to be recovered; receiving the transistor-level netlist; selecting a set of connected components from the transistor-level netlist; functionally describing the set of connected components using the first transistor model; generating a signature for the set of connected components; comparing the signature of the set of connected components to the signature of each gate to be recovered; if the signature of the set of connected components matches a signature of a to be recovered then determining if the corresponding functional descriptions match; if a match occurs then functionally describing the set of connected components using a second transistor model; comparing the functional descriptions generated for the set of connected components using the first and second transistor models; identifyi
