Board Layout Guidelines

NOTE: Each interface will set the trace spacing based on its signal integrity of differential impedance requirements. For the purposes of the building the transmission line models, it is assumed the artwork is very accurate and therefore a constant. Thus, all the variability in the trace spacing is the result of the tolerances of the trace width.
