Description

technical field [0001] The present application relates to the technical field of circuit design, in particular, to a circuit simulation method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Random chip technology is getting higher and higher, and chip design is becoming more and more complex. The power supply connected to the source of the MOS tube needs to be connected through multiple layers of metal or semiconductor levels, resulting in the resistance formed by the power supply network being too large to be ignored. [0003] Therefore, for the accuracy of circuit simulation, the existing circuit simulation needs to include the parasitic parameters of the power network for simulation. However, due to the relatively complex parasitic parameters of the power network, the time of circuit simulation and the consumption of machine resources have greatly increased. Contents of the invention [0004] The purpose of the present...
