Abstract
A method of searching paths that are susceptible to electrostatic discharge (ESD) at the beginning of an integrated circuit (IC) design is disclosed that includes a circuit spreading out algorithm, a matrix closure algorithm, and a supernode algorithm. The found paths are required to satisfy conditions including that (a) they are connected from a gate of a transistor to a source or a drain thereof, and (b) the head node and the tail node of each path are pins of a top level of the IC. −1/0/1 matrix multiplication is employed by both the circuit spreading out algorithm and the matrix closure algorithm so as to obtain a result of node connections after a plurality of matrix self-multiplications.
