A data average operation rate by time of day is anticipated based on the memory operation rate by time of day and the degree of memory influence. A point of change where a change in data operation rate is greater than a threshold value is selected as a waveform acquisition point. At the waveform acquisition point, a simulation of the overall subject of design is conducted to acquire waveform data only for a designated period. The data average operation rate by time of day is calculated on the basis of the waveform data obtained. The power consumption is estimated based on the memory operation rate by time of day.  <P>COPYRIGHT: (C)2009,JPO&INPIT
