Abstract

The authors study the problem of minimizing channel density by shifting the blocks that form the sides of the channel and the terminals on the boundary of each block. Several special cases of this problem have been investigated, but no polynomial time algorithm was known for the general case. The authors present a polynomial time optimal algorithm for solving this problem. For long channels, they propose heuristic approaches to speed up the algorithm. Extensions as well as applications of the algorithm to detailed routing in building-block layout design are also discussed. Preliminary experimental results are very promising. Substantial reductions in routing area were obtained in moderate computation time.
