im simulating a filter in ADS with two spiral inductors (coil) at the layer 3 and layer 4.
however, my layer 1 has RF traces and components, layer 2 is GND, layer 3 is a coil and layer 4 is another coil. i selected GND layer as slot. the rest of the layers are strip layers with finite copper thickness (not sheet metal). However, im not getting correlation between layout simulation and circuit simulation with "TL-multilayer".
i have a feeling that ADS not simulating inner layers well even if i define it as strip layer with finite copper thickness. Please let me know if my analysis is correct.
