Crosstalk Minimization Using Wire Perturbations

We study the variation of the crosstalk in a net and its neighbors when one of its trunks is perturbed, showing that the trunk’s perturbation range can be efficiently divided into subintervals having monotonic or unimodal crosstalk variation. We can therefore determine the optimum trunk location without solving any non-linear equations. Using this, we construct and experimentally verify an algorithm to minimize the peak net crosstalk in a gridless channel.
