The routing problem has come to assume a position of significance with the rapid advances in VLSI technology. Seven contributions from researchers and practitioners discuss modern developments in routing techniques, gridless routing for macro-cell design, placement, VLSI placement, partitioning, channel definition in VLSI building-block layout and optimal determination of block dimensions in general floorplans. The CIP incorrectly identifies the series as "Computer engineering and computer science." Annotation copyright Book News, Inc. Portland, Or.
