Abstract :
A novel technique for deriving the variance waveform for CMOS circuits is presented. Using this technique, the authors establish the importance of the variance waveform by showing that its contribution to the mean-time-to-failure estimate can be in the range of 100% to 200% relative to that of the expected waveform. The technique has been built into the probabilistic simulator CREST and has shown good agreement with SPICE, as well as excellent speedup.<>
