Interconnection length estimation for optimized standard cell layouts

An accurate model for the prediction of interconnection lengths for standard cell layouts is presented. On the designs in the test suite estimates are within 10% of the actual layouts. The model abstracts the important features of placement, global routing, and channel routing. The predicted results are obtained from analysis of the net list. No prior knowledge of the functionality of the design is used. Accurate prediction of the interconnection length is useful for estimating the actual layout area, for evaluating the fit of a logic design to a fabrication technology, and for solving placement and routing algorithms.<>
