  • Patent number: 8224637
    Abstract: An aspect of the invention relates to modeling a transistor in an integrated circuit design. Layout data for the integrated circuit design is obtained. A geometry relating the transistor to at least one well edge of at least one implant well is extracted from the layout data. An effective well proximity value for the transistor is calculated based on the at least one well edge using a complementary error function. The transistor is modeled using the effective well proximity value. In one embodiment, the effective well proximity value is added to a post-layout extracted netlist for the integrated circuit design. The integrated circuit design may be simulated using the post-layout extracted netlist. The effective well proximity value may be used to calculate a threshold voltage for the transistor during the step of simulating the integrated circuit.
