Interconnection analysis for standard cell layouts

We present an accurate model and procedures for predicting the common physical design characteristics of standard cell layouts i e the interconnection length and the chip area The predicted results are obtained from analysis of the net list only that is no prior knowledge of the functionality of the design is used Random and opti mized placements global routing and detailed routing are each abstracted by procedural models that capture the im portant features of these processes and closed form expres sions that de ne these procedural models are presented We have veri ed both the global characteristics total intercon nection length and layout area and the detailed charac teristics wire length and feedthrough distributions of the model On the designs in our test suite the estimates are very close to the actual layouts
