Abstract:
A wiring designing method for designing an intersection portion of stripe wirings composed of a plurality of strands limited to a fixed width or lower, comprising:a virtual intersection step for setting first and second stripe wirings composed of a plurality of strands limited to a fixed width or lower to virtually intersect each other; a strand setting step for setting, among strands in intersection portion of the first and second stripe wirings, a strand belonging to any one of the first and second stripe wirings as a strand to be changed for position; a reference position decision step for deciding a reference position; and a strand moving step for moving the strand to be changed for position in a direction away from the reference position to a position where an occupancy rate of a wiring for each of the first and second stripe wirings in the portion of intersection becomes equal to/lower than at least a maximum occupancy rate of a wiring decided by constraints imposed on a manufacturing process.
