Abstract: Simulation waveforms representative of simulation progress are generated and outputted for display. A netlist describing a circuit is accessed, and the circuit is simulated over a simulation runtime period. A simulation completion measurement is determined for the simulation runtime period, and a simulation waveform is generated based on the determined simulation completion measurement. Other simulation waveforms can be generated, for instance waveforms representative of a processing resource load over the simulation runtime period. Multiple simulation waveforms can be correlated and displayed in conjunction with each other, for instance in a common waveform interface.
