Accompanying with the popularization of portable equipments, and the rapid growth of the size of the electric systems, efficient low power design methodologies have been highly required. To satisfy these requests, a high accurate and high efficient power analysis in higher abstraction level is very important. The design environment is composed by efficient algorithms of power modeling, power library building, and data extracting. Those components of the environment should be balanced for the total efficiency and accuracy. We have proposed a new efficient power modeling environment which uses a look-up table (LUT). It reduces the size of the LUT drastically, compared to conventional algorithms. It makes the power analysis and library building high efficient. The experimental results show that our approach reduces the computation time to build the library to one tenth while keeping the accuracy of the power analysis. The RMS error and the largest error has been less than 8.30%, 59.16%, respectively.
