Dynamic power estimation based on switching activity propagation

Abstract : A new power estimation approach based on the decomposition of a digital system into basic operators is presented. This approach aims to estimate the energy consumption at early design phases of digital blocks implemented on FPGAs. Each operator has its own model which estimates the switching activity and the power consumption. By interconnecting several operators, statistical information is then propagated to provide a global power estimation of a given system. A simple sum of the power dissipation contribution of each operator is enough to compute the total power consumption. This is performed by taking into account the switching activities relative to a given input pattern. Earlier, faster and more flexible power analysis for system designers are the advantages. This approach has been evaluated in a use-case application. The preliminary results indicate a promising speed-up of the design process and an error which is less than 8.0% compare to the classical power estimation tools.
