Traditionally placement evaluation metrics have been based on wirelength and congestion measures and are independent of the logic network topology. However, the actual timing measure, which is used in a design closure loop, is path-based and dependent on the network topology. In this paper, we propose a design-topology aware metric that encapsulates the structural property of the circuit and physical goodness of the given placement. We present such a metric which is based on path monotonicity and an efficient method to compute this measure for a given placement. This method involves abstract path generation, clustering based region refinement and physical monotonicity analysis. Experimental results on real industry designs, using a commercial strength design closure flow, establish the usefulness of this metric in predicting the quality of a given placement with respect to design timing closure.
