Abstract
A method for automatically wiring (i.e., routing) an integrated circuit chip after completing the placement of cells on the chip is described. The method employs a maze routing such that the spacing between the routed wires is increased, while at the same time maintaining control over the total wiring length. The maze routing herein described is modified to improve chip yield, reduce wiring capacitance, limit power consumption and coupled signal noise, all of which are achieved by increasing wire-to-wire spacings.
