A robust signal transition density propagation method for a zero delay model is presented to obtain the signal transition density for estimating the power consumption. The power estimation for the zero delay model is a proper criteria for the lower boundary of power consumption. Two important estimation methodologies had been proposed. While one method has some accuracy problem because of ignoring a simultaneous signal effect, the other method shows some unstable results, being caused by introducing the normalized signal transition density. Hence this paper will explore the method to achieve the robustness and accuracy of the signal transition density estimation by taking the input output transition behavior into account. We present a signal transition density estimation method by eliminating that redundancy. In experiments, the proposed methodology shows better robustness, comparable accuracy and elapsed time compared to the conventional methods
