Embodiment Construction
[0151] Now in conjunction with Fig. (14) the present invention is described in detail according to the following steps:
[0152] 1. The computer reads the information file of the circuit, which includes the correlation structure between nodes; the resistance value, inductance value, initial voltage and current value of the inductor, capacitance value, initial voltage and current value of the capacitor, and the connection of each node The time-varying sink current waveform of the power supply module unit (expressed by PWL, such as Figure 12 ), based on which the topology of the circuit is established in the computer and its electrical parameters are recorded.
[0153] 2. Establishing According to the working cycle of the circuit and the number of cycles to be simulated, the computer reads in the corresponding time step h and the total number of simulation steps M; select the appropriate number of simplified levels L and the accuracy requirements of the simulation ε
