Abstract: A layout routing method includes determining a routing pattern according to a swapping rule, a via pattern, area constraints and pin locations; optimizing swapping in differential pairs according to the routing pattern; extracting features of each routing net to obtain extracted features; using an unsupervised algorithm to generate different routing groups according to the extracted features; and determining a routing order of the routing groups according to complex features of the routing groups.
