Circuit simulation method and device, electronic equipment and computer readable storage medium

The invention provides a circuit simulation method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: dividing a netlist circuit into a plurality of sub-circuits according to a hypergraph division rule and initial information of the netlist circuit; modeling the plurality of sub-circuits in parallel to obtain a BBD matrix; solving a block diagonal matrix of the BBD matrix in parallel to obtain a comprehensive calculation result of the netlist circuit so as to complete netlist circuit simulation; wherein the BBD matrix is of a single-layer BBD structure. According to the method, the netlist circuit is divided into the plurality of sub-circuits, the plurality of sub-circuits are analyzed and solved in parallel, and finally the calculation results of the sub-circuits are synthesized to obtain the final simulation result, so that the overall calculation time of the netlist circuit is saved, and the circuit simulation efficiency is improved. 本申请提供了一种电
