Expecting keyword STIMULUS or device X_F1.V1 is undefined - OrCAD 16.5

jlgm

 Hello

I have a problem. I can't simulate a circuit because the models are missing. I am new to OrCAD (all versions) so I was creating a schematic of a buck converter. I should be able to simulate but I can't.
Please let me know exactly how to resolve it. Here are the netlist & the errors. Thank you very much

    1st sample: VF_F1 has too many nodes for an independent voltage source, should be V<name> +node -node then the DC / AC parameters. (For a DC, or AC, declaration, PSpice will know that you mean "volts DC", or "volts AC", there is no requirement to specify Vdc, or Vac, in the value)

    2nd sample, this subcircuit:

    .subckt SCHEMATIC1_F1 1 2 3 4 
    F_F1         3 4 POLY(2) V1 VF_F1 0.0 2.0 1.0
    VF_F1         1 2  DC 0V AC 0V
    .ends SCHEMATIC1_F1

    is trying to reference node V1 as a controlling input for the "POLY", but there is no node of that name in the subcircuit.
