With a total of 2 patents, his work showcases innovative methods and systems that enhance the reliability of electronic devices.

Latest Patents

One of his latest patents is titled "Systems and methods to generate a test bench for electrostatic discharge analysis of an integrated circuit design." This invention discloses embodiments of systems, methods, and products that automatically and intelligently generate a test bench to test an ESD protection circuit in an integrated circuit (IC) design. A computer receives a netlist of the IC design forming a device under test (DUT). From the DUT, the computer extracts and/or calculates one or more parameters. Based on these parameters, the computer generates a test bench comprising a resistance inductance capacitance (RLC) circuit to provide ESD stimulus to the DUT. The ESD stimulus and the test bench may be based on a human body model (HBD) or a charged device model (CDM). In the case of the CDM, the computer allows a circuit designer to select or deselect package parameters for testing the ESD protection circuit.

Another significant patent is the "Method to adaptively calculate resistor mesh in IC designs." This method utilizes an adaptive square mesh for parasitic extraction. Small squares of a predetermined minimum size are placed where accuracy in the parasitic calculations is most critical, such as around edges, contacts, vias, and corners. In areas where the parasitic analysis is less critical, a more coarse grid consisting of larger squares is used to calculate the parasitic values. The squares in the mesh may increase in size gradually to provide more accurate results.
