Abstract
A method for accurately performing a timing, power, and noise analysis by pre-processing the characterization points of the available libraries, storing time consuming parts of the analysis and utilizing the pre-processed information during active runs to calculate the attributes at a desired PVT point. The PVT space is preferably sub-divided into triangular or rectangular regions, preferably obtained using Delaunay triangulation. In one embodiment, the invention performs an up-front pre-processing step on the characterized libraries to compute the static portion of the interpolation function that is independent of the specific instance; and a coefficient matrix that allows for interpolation of specific instances.
