Advanced cell-aware fault model for yield analysis and physical failure analysis

Abstract:

To specifically identify faults within a semiconductor cell, a SPICE netlist associated with the semiconductor cell design is retrieved, and one or more transistor characteristics are identified within the SPICE netlist. An advanced cell-aware fault model is executed for the semiconductor cell, and results are returned for one or more fault test methods of the advanced cell-aware fault model for a cell of the semiconductor chip design. A method for identifying faults within the semiconductor cell continues by correlating one more faults detected as a result of the fault test methods with one or more transistor characteristics within the SPICE netlist, and a user interface is generated for identifying one or more faulty transistors within the semiconductor chip design.
