Title:
CIRCUIT SIMULATION METHOD AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/016485
Kind Code:
A1
Abstract:
A circuit simulation method and an electronic device. The method comprises: acquiring electrostatic protection actual measurement data corresponding to one or more target electrostatic protection circuits and a plurality of preset electrostatic pulses of different amplitudes (S1); for each target electrostatic protection circuit, establishing, according to the actual measurement data, a virtual circuit model in one-to-one correspondence with the target electrostatic protection circuit (S2); acquiring a post-simulation netlist of a circuit to be simulated, the circuit to be simulated comprising one or more target electrostatic protection circuits, and the post-simulation netlist comprising one or more first-type sub-netlists corresponding to the one or more target electrostatic protection circuits (S3); replacing information in the first-type sub-netlist corresponding to each target electrostatic protection circuit with information of a virtual circuit model corresponding thereto (S4); and simulating the circuit to be simulated on the basis of the replaced post-simulation netlist. According to embodiments of the present disclosure, circuit simulation of an ESD device having a folding characteristic can be achieved.
