Abstract

Disclosed herein are embodiments of systems, methods, and products to automatically and intelligently generate a test bench to test an electrostatic discharge (ESD) protection circuit in an integrated circuit (IC) design. A computer may receive netlist of the IC design forming a device under test (DUT). From the DUT, the computer may extract and/or calculate one or more parameters. Based on the one or more parameters, the computer may generate a test bench comprising a resistance inductance capacitance (RLC) circuit to provide ESD stimulus to the DUT. The ESD stimulus and therefore the test bench may be based on a human body model (HBD) or a charged device model (CDM). In case of the CDM, the computer may allow a circuit designer to select or deselect package parameters for testing the ESD protection circuit.
