Ground Vs. Power Planes & Impedance

Question asked by dupre on Jul 23, 2013

I note that Hyperlynx LineSim does  not differentiate between power and ground planes in a layer stackup.   Does this mean there is no difference between power and ground planes  when defining a controlled impedance stack-up?  I was always under the  impression that you reference a controlled impedance trace to adjacent  ground plane(s).  Does a power plane do the same thing???
