Circuit simulation method, circuit simulation device, medium and electronic equipment

Abstract

The invention provides a circuit simulation method, a circuit simulation device, a medium and electronic equipment. The circuit simulation method comprises the following steps: acquiring a circuit netlist of a target integrated circuit as a first circuit netlist, wherein the first circuit netlist comprises internal nodes and port nodes; processing the first circuit netlist to obtain a node to be reserved in the first circuit netlist, wherein the RC time constant of the node to be reserved is greater than the average RC time constant of internal nodes of the first circuit netlist; removing the node to be reserved from an internal node of the first circuit netlist, and adding the node to be reserved into a port node of the first circuit netlist to generate a second circuit netlist; performing reduction processing on the second circuit netlist to obtain an equivalent circuit; and performing circuit simulation on the equivalent circuit through a circuit simulator of the electronic equipment. According to the method, the calculation amount in the simulation process of the large-scale integrated circuit can be reduced, and the simulation complexity is reduced.
