Patent ID: 10922456

Abstract:
The present embodiments relate to electrostatic discharge (ESD) simulation of integrated circuit designs. A netlist of the circuit design can be modified to include ESD protection devices and only essential non-ESD devices. The essential non-ESD devices can be determined based on whether a non-ESD device satisfies one or more of two conditions: (i) a least resistance path (LRP) value of at least one terminal of the non-ESD device from any port of the set of ports is less than a first threshold value or (ii) an effective resistance value between at least one terminal of the non-ESD device from any port of the set of ports is less than a second threshold value. The essential non-ESD devices are included in a reduced netlist in addition to the ESD protection devices. The ESD simulation is carried out on the reduced netlist, thereby reducing simulation time.
