Abstract
Method for obtaining a difference in lengths among a plurality of signal traces formed on two different surfaces, includes dividing a propagation delay of a first surface into a propagation delay of a second surface to obtain a correction factor. The segment of the signal traces formed on the second surface is adjusted by multiplying the correction factor to this segment. Then, the adjusted segment is summed with the segment of the signal traces formed on the first surface to obtain a total length. The total length of each of the signal traces is subtracted from the longest total length of the signal traces.
