I have a design that needs to route several 1Gbps links, each link has 12 bits. The design rule that we have specified is 50mil spacing between links on the same and opposing dual strip line layers. The question comes when one link crosses another link orthogonally, what should the rule be for the distance from the crossing point to where the trace begins not being perpendicular?
