Dear experts,

Sorry to disturb you again. :) The following figure explains the case =
more clearly:

________ ________ ________ ________
|________| |________| |________| |________|
GND Signal GND Signal

So they are not driven differentially. General tools calculate =
differential impedance, right? Can just setting the distance to the =
plane very high get correct result?

Thanks for your help and look forward to your reply.
