Abstract A ‘greedy’ channel-router is presented. It is quick, simple and effective. It always suceeds, usually using no more than one track more than required by channel density. It may be forced in rare cases to make a few connections ‘off the end’ of the channel, in order to succeed. It assumes that all pins and wirling lie on a common grid, and that vertical wires are on one layer, horizontal on another. The greedy router wires the channel left-to-right, column-by-column, wiring each column completely before starting the next. Within each column the router tries to maximize the utility of the wiring produced, using simple, ‘greedy’ heuristics. It may place a net on more than one track for a few columns, and collapse the net to a single track later on, using a vertical jog. It may also use a jog to move a net to a track closer to its pin in some future column. The router may occasionally add a new track to the channel, to avoid getting stuck.
