Hi Uri,
Before you get into material.dat file, and the parameters and what-not, I
experimented with changing some variables in my stackup and the impedance
DIDN'T change. I tried FR4 over top; conformal coat; etc; changed
thicknesses; Dk and when I do DISPLAY/PARASITICS on my Clines nothing
changes. Might be worth your time to experiment first. :)
