Claim Text:
1. A method for identifying an optimal harmonic number of a circuit, the method comprising: simulating, with a processor, the circuit with a transient simulation of information representative of an integrated circuit design corresponding to the circuit, the transient simulation of the circuit including applying a periodic input waveform up to a particular number of periods and obtaining an output waveform in response, the output waveform modeling instantaneous circuit output values as a function of time; upon detecting, by the processor, a steady state response of the output waveform, performing the transient simulation on the circuit for an additional period of the periodic input waveform beyond the particular number of periods, and obtaining a further output waveform corresponding to the additional period of the periodic input waveform; calculating, by the processor, at least a time domain power value and a frequency domain power value using the further output waveform corresponding to the additional period of the periodic input waveform; and detecting, by the processor, a harmonic of the further 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.
