A quick simulation method and apparatus for an integrated circuit, and a storage medium, are provided, wherein, by dividing a large-scale integrated circuit into a plurality of sub-circuit, then performing simulation on each sub-circuit, generating a corresponding function correspondence relation formula for each of those sub-circuits for which a simulated waveform is a periodic waveform, and then, when performing simulation on the large-scale integrated circuit, directly performing simulation on each of those sub-circuits for which the waveform is not a periodic waveform, and performing calculation by using the function correspondence relation formula corresponding to each of those sub-circuits for which the simulated waveform is a periodic waveform to complete a corresponding simulation thereof, so as to realize a simulation for the whole large-scale integrated circuit. Wherein, because an output waveform obtained according to the function correspondence relation formula is the same as the simulated waveform obtained by directly performing simulation, there is no need to perform complicated matrix calculations on the circuit, thereby improving the simulation speed when the integrated circuit is subject to transient analysis.
