Abstract :
A new approach for power modeling of transversal filters based on a physically oriented design is presented. The approach is based on algebraic models fitted by correction functions which are determined from the distribution of the simulated, actual switching activity within filter macros. With these functions, even the dependency of the power models on input switching activities and statistical distribution of input signals becomes feasible. With the continuous progress in CMOS technology, such accurate and parameterizable power models become more and more important, especially in an early system design step.
