Flexibility in size parameters, such as bitwidths, is a key requirement for high level power models of soft macros. To meet this requirement many modeling approaches rely on functions that relate the design complexity to the macro size parameters. So far such functions had to be produced by careful manual analysis of the internal macro structure. This method is tedious and error prone especially for IP components. In this paper we present a methodology to generate exact complexity functions automatically. Our approach is based on a special form of nonlinear regression. It blends into the model generation process seamlessly.
