Abstract
Presents a procedure for reducing the probability of undetectable shorts occurring between horizontal wires. This procedure is implemented by modifying a channel router to predict many of the shorts that are undetectable and then place the associated signal wires in nonadjacent tracks. For the designs routed, it is found that the probability of an undetectable nonfeedback short between horizontal lines in the routing channels is reduced by 39.9% with no increase in the number of routing tracks required and little increase in routing computation cost
