pattern-independent current estimation for reliability analysis of cmos circuits
Accurate and efficient expected current estimation is required in circuit designs to analyze electromigration failure rate, power consumption, voltage drop, etc. A new pattern-independent simulation approach for estimating this expected current waveform drawn by CMOS circuitry has been developed. Four original concepts, probability waveforms, probability waveform propagation, probabilistic circuit model, and statistical timing analysis, are presented which allow an efficient and accurate estimation of expected current waveforms. This approach is dramatically faster than traditional methods and yields comparable results.
