It is known that circuits exhibit multiple modes of power consumption due to various factors such as the presence of many feedback (or sequential) elements, RAM, large size, etc. Previous power-estimation techniques have largely ignored this fact. For example, Monte Carlo simulation-based power estimators tend to produce estimates for the average power consumption that corresponds only to the most...
A maximum-likelihood estimation procedure for computing the average power consumption of VLSI circuits is proposed. The method can handle data that has a mixture-density with multiple components unlike most of the previous approaches. An iterative computational procedure based on the expectation-maximization principle is also discussed. This can be used to estimate the parameters of an arbitrary (but...
