Interconnect wire length estimation for stochastic wiring distributions

This paper presents an improved stochastic wiring distribution model. The model is an improvement and modification of the models presented in some prior works available in literature. The proposed model shows 28% - 50% reduction in error when estimating the average interconnect wire length compared to existing models. This paper also investigates the effect of Rent´s exponent on the average wire length estimation. This investigation leads to the identification of some limitations of the approximations found in recent models.
