Propagation algorithm of behavior probability in power estimation based on multiple-valued logic

This paper analyses the propagation operations of signal's multiple-valued behavior while passing through the basic gates. Based on it the propagation algorithm of behavior probability is proposed. In comparison with the propagation algorithm of signal probability this algorithm have advantages that the calculation is direct one and the glitches resulted from race hazard can be taken into account, whereby the estimation accuracy of power dissipation can be improved.
