Some embodiments provide identification of a first polyline and a second polyline associated with a differential signal, determination of whether a distance between a segment of the first polyline and a segment of the second polyline is within a first tolerance, determination, if the distance is not within the first tolerance, of whether the distance is within a second tolerance, determination, if the distance is not within the first tolerance and is within the second tolerance, of whether the length of the segment of the first polyline is less than a first threshold, and to indicate that the first polyline and the second polyline are sufficiently spaced, if the distance is not within the first tolerance and is within the second tolerance, and if the length of the segment of the first polyline is less than the first threshold.
