Abstract:
1. A semiconductor device, comprising: a first set of signal wires, including a first plurality of signal wires distributed in a first layer and a second plurality of signal wires distributed in a second adjacent layer; a second set of signal wires, including a third plurality of signals wires distributed in the first layer and a fourth plurality of signal wires distributed in the second layer, the first and second sets having a different number of signal wires, with the signal wires in the first set being substantially parallel and arranged in a first pattern, and the signal wires in the second set being substantially parallel and arranged in a second pattern, wherein: the first and second layers are on different vertical levels of said device, the signal wires in the first layer and the signal wires in the second layer extend along different longitudinal axes which do not intersect, and said device further includes one or more ground or return wires that extend parallel to the signals wires in the first and second sets, the ground or return wires disposed between the signal wires in the first set and the signal wires in the second set.
