ABSTRACT:
A method for routing signals in a multilayer substrate is disclosed. One embodiment of a method may comprise providing a multilayer substrate with at least one differential signal line pair aligned along a common plane that is substantially transverse to a top surface of the multilayer substrate, jogging a first differential signal line associated with a differential signal line pair at a first redistribution layer in a direction along the common plane, and jogging a second differential signal line associated with the differential signal line pair at a second redistribution layer along the common plane in a same direction as the first differential signal line to provide a substantially balanced differential signal line pair.
