{ A new method for power estimation in sequential circuits is presented that is based on a statistical estimation technique. By applying randomly generated input sequences to the circuit, statistics on the latch outputs are collected, by simulation, that allow ecient p o w er estimation for the whole design. An important advantage of this approach is that the desired accuracy can be specied up-front b y the user; the algorithm iterates until the specied accuracy is achieved. This has been implemented and tested on a number of sequential circuits and found to be much faster than existing techniques. We can complete the analysis of a circuit with 1,452 ip-ops and 19,253 gates in about 4.6 hours (the largest test case reported previously has 223 ip-ops).

In this paper, we propose Fourier–Boas-Like wavelets and obtain sufficient conditions for their higher vanishing moments. A sufficient condition is given to obtain moment formula for such wavelets. Some properties of Fourier–Boas-Like wavelets associated with Riesz projectors are also given. Finally, we formulate a variation diminishing wavelet associated with a Fourier–Boas-Like wavelet.
