1. A method for estimating a static power consumption of an integrated circuit, the method comprising: dividing the integrated circuit into at least one cell; characterizing a static power consumption of a cell based on a contribution of an input node and a contribution of an output node of the cell, each contribution representing a multiplication of a leakage coefficient and a probability of a node; determining a value of a leakage coefficient of a node; determining a value of a probability of a node; and calculating a static power consumption of the cell to determine the static power consumption of the integrated circuit; wherein a leakage coefficient of a node is determined as a coordinate of an orthogonal projection of a vector representing the static power consumption of the cell into a base of vectors representing the input node, the output node and a constant.
