I end up with a schematic for a subcircuit that seems to be fine, no complaints from the Netlist Translator, but when I place this as a component to another schematic and run the simulation, I get this:

I googled "ADS_SPC_IF" and found very few results, so I figured this isn't even part of ADS Extension Language. This must've been generated at preprocessor stage or something. So maybe the original PSPICE netlist must've not been translated correctly. I don't know PSPICE nor do I have time to learn it.

So I'm asking if anyone of you can verify if the original PSPICE netlist was translated correctly and if so where is the actual problem here.
