Abstract: The subject technology provides a method and apparatus for performing dual track routing. A pair of signal traces is routed in between two rows of contacts and at least one of the signal traces is modified to satisfy a routing restriction. The modification of the signal trace includes three trace segments that deviate the signal trace away from the source of the routing restriction.

Abstract: A method and apparatus for matching the lengths of traces of differential signal pairs. The method includes determining that a first trace is longer than a second trace and modifying the second trace so that the length is substantially equal to the length of the first trace. In some implementations, the second trace can be modified by replacing one or more sections of the trace with two line segments that are substantially equal in length and meet at a vertex that is less than 180 degrees.
