摘要： First and second pin groups are each formed from a plurality of pins associated with specific nets. Pins in the first pin group are to be wired to pins in the second pin group according to their associated nets. A candidate selection unit selects a set of pair candidates each specifying a first pair of pins in the first pin group and a second pair of pins in the second pin group. The first and second pairs of pins are associated with the same pair of nets, and their respective distances are within a specified range. A pair determination unit determines which pins in the first and second pin groups are to be wired in pairs, based on the pair candidates selected by the candidate selection unit.
