INTEGRITY OF WAVEFORM SIMULATION

摘要

This paper presents of experimental results for verifying integrity of waveform simulation. To compare accuracy and speed of simulation between SPICE and Boolean process based waveform simulation, we simulate the combinational circuits of ISCAS'85 with both. Experimental results show that the output waveforms of Boolean process based waveform simulation is considerably consistent with that of SPICE, but several ten thousands times faster than HSPICE. Factors that contribute the most to component delay are analyzed. A more accurate delay model, 3-FACTOR, is then introduced to further reflect practice when the waveform simulator is applied.
