摘要
An apparatus and method for identifying an optimal harmonic number of a circuit are disclosed. In a simulation of the circuit, a periodic input waveform up to a particular number of periods is applied to the modeled circuit and an output waveform is obtained in response. In response to detection of a steady state response of the output waveform, embodiments simulate the circuit by applying an additional period of the periodic input waveform and obtaining the output waveform corresponding to the additional period of the periodic input waveform. A time domain power value and a frequency domain power value are calculated using the output waveform corresponding to the additional period of the periodic input waveform. Embodiments detect a harmonic of the output waveform corresponding to the additional period of the periodic input waveform at which the time domain power value and the frequency domain power value converge with each other.
