That=E2=80=99s because you put them in as symbols in the schematic. =
Don=E2=80=99t do it that way. Give your components the interfaces they =
need behind their pins. Use explicit SPICE code in the spice-prototype =
or draw a simulation schematic of the component and refer to that as a =
subcircuit in your spice-prototype, but not in a source attribute.
