[PSES] SV: [PSES] Stripline - discontinuity in adjacent ground planes

Note that the worst situation may occur when both planes are equal, In this PCB, they are more or less equal. It's an 8-layer stack (bottom/ Layer8=GND, Layer7=Signals, Layer6=GND, and .). But the signal traces in Layer7 have now continuous return path in both L8 and L6. Regards Amund

GND1-Signal = 200um Signal-GND2 = 220um So there are slightly differences of the distances. I have found two possible alternatives to change layout so the high speed lines in Signal layer will have 100% GND return coupling all the way. They should must have priority when interfering other
