Abstract:The bottleneck of voltage drop analysis lies in the matrix inversion that is involved in solving the circuit equations of the power/ground bus. To remove the bottleneck, we proposed an algorithm to quickly estimate the cycle-by-cycle maximum voltage drop values of a circuit driven by an input sequence. Based on the rank of the estimates, a small set of input vectors is selected for detailed analysis to identify the worst-case voltage drop behavior. The pruning strategy has been applied to a set of industry designs and is found to be on average three times faster than direct network analysis. Compared to a straightforward approach of using the total power as the estimator, the proposed algorithm demonstrates higher run-time efficiency and better consistency with the actual simulation results.
