Abstract：
 The invention belongs to normal element IC CAD technical field. Based on initial solution of loose routing obtained from optimization of wiring squash and circuit time delay, the method carries out cross talk elimination according to cross talk restriction setup by user. In eliminating cross talk, through conventional distributing cross talk restriction, the method eliminates cross talk on each GRG edge by using prohibition-searching method. Specifically, based on constructed cost function as judging criterion, from current solution as starting point, the method searches rightful candidate solution set in neighborhood by carrying iteration till specified time of iteration, further optimization is carried out. The method obtains result of insertion number of shielded line near to number obtained from simulated annealing method, but, shortening execution time greatly and reducing half line increment.
