Abstract

With the increasing sophistication of circuits and specifically in the presence of IP blocks, new estimation methods are needed in the design flow of large-scale circuits. Up to now, a number of post-placement congestion estimation techniques in the presence of IP blocks have been presented. In this paper we present a unified approach for predicting wirelength, congestion and delay parameters early in the design flow. We also propose a methodology to integrate these prediction methods into the placement framework to handle the large complexity of the designs.
