hi everyone,

 i have a Layout with EM and i want to generate it to EM symbol and connect  Lump resistors (pi attenuator) so i don't   .

.know how to define my port because i have GND planes(2 layers)  in the layout and the pi attenuator at the TOP layer

???how i need to define my port differential or with global GND 

 it's ok if I define the P7 positive and P8  negative and  P9 positive and P10  negative and  P11 positive and P12 negative.


Port1: P1 positive terminal, P2 and P3 negative terminals

Port2: P4 positive terminal, P5, P6 negative terminals.


 in this illustrate i didn't use with global GND symbol and all the ports are diffirentials


 Note: the blue points they Vias ,connect the top GND and the layer 2 and layer 3 GND and they are defined in the substrate  like this



(in addition, the question is if the layers 2 and 3 need to be defined as a slot plane or like this(strip plane
