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.

Checks for signal lines

Design checks for signal lines

A first circuit layout design is obtained, and a second circuit layout design is obtained. A first topology graph is generated for the first circuit layout design, and a second topology graph is generated for the second circuit layout design. The first topology graph and the second topology graph are compared to obtain a comparison result. The comparison result is reported.

Comparison of circuit layout designs

A system to evaluate a distance between polyline segments includes 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, and, if the distance is not within the first tolerance, determining whether the distance is within a second tolerance. If the distance is not within the first tolerance and is within the second tolerance, it is determined whether the length of the segment of the first polyline is less than a first threshold. 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, it is indicated that the first polyline and the second polyline are sufficiently spaced. If the distance is not within the second tolerance or if the length of the segment of the first polyline is greater than the first threshold, it is determined whether the segments are located near a device pin, and, if the segments are not located near a device pin, it is indicated that the first polyline and the second polyline are not sufficiently spaced.
