Application of STD to latch-power estimation

摘要

In this paper, we use the recently developed static transitionndiagram technique to derive analytical formulas expressing latch powernin terms of true and spurious switching activities at the data input.nThese formulas are verified through analog simulation and applied to annumber of commonly used latch designs. The derived model will allowndesigners to substitute parameters of true and spurious switchingnactivities into analytical formulas for quickly obtaining accurate latchnpower and then select latches which have the best power-dissipationncharacteristics for those parameter values
