I am simulating differential via having cases of back-drilling and without back-drill in order to observe impedance discontinuity. I selected the required 3D area and exported in 3D solver and observed return and insertion loss, while doing back-drill return loss should decrease return loss is increasing in my case while i am doing backdrilling. I think i am lagging in port assignments initially while exporting it asked for port for lower reference and upper reference, I assigned it as lower reference.

Can anyone help me in assignment of ports properly.
