The inter-wire spacing in a VLSI chip becomes closer as the VLSI fabrication technology rapidly evolves. Accordingly, it becomes important to minimize crosstalk caused by the coupling capacitance between adjacent wires in the layout design for the fast and safe VLSI circuits. We present a simulated annealing approach based on segment rearrangement to crosstalk minimization in an initially gridded channel routing. The proposed technique is compared with previous track-oriented techniques, especially a track permutation technique whose performance is bounded by an exhaustive track permutation algorithm. Experiments showed that the presented technique is more effective than the track permutation technique.
