Abstract
A method for minimizing cycle time to improve machine performance is described. The approach prioritizes placement and partitioning decisions based on the criticality of paths and their constituent net segments. It provides an initial coarse approximation to a final more optimum configuration by iteratively improving on it through the use of deterministic techniques. The method optimizes placement by means of heuristic algorithms that are based on a cost function that is dependent on net segment and path criticality.
