ABSTRACT:
A method of estimating the power consumption of a semiconductor integrated circuit provides second data for primary inputs of a logic part in the integrated circuit and for nets that determine the signal value of a given net in the logic part. The second data has a multi-terminal Boolean approximation method (MTBAM) data structure. The method prepares first data having the MTBAM data structure from a probability contained in the second data, probabilities calculated according to third data contained in the second data and having a multi-terminal binary decision diagram (MTBDD) data structure, and fourth data generated from the third data and having the MTBDD data structure. According to the first data, the method estimates a probability for the given net. The method prepares such first data for all nets in the integrated circuit, and according to which, estimates the power consumption of the integrated circuit.
