A method for generating a compressed representation of a simulated waveform is disclosed. The method may have the steps of: (a) processing circuit model information, (b) identifying a segment of stable repetition; and (c) generating the compressed representation. Step (a) may generate waveform information representing a simulated waveform occurring in the circuit model. Step (b) may identify the segment in the waveform information. In step (c), the compressed waveform information may define the segment by (i) cycle information representing the waveform cycle and (ii) repetition information representing the stable repetitions of the waveform cycle to form the segment.
