.ends OPA694_F4 *comment out for Spice3F4
When i use it ,some wrongs like the fellowings happened,
ERROR -- Subcircuit 3F4 used by X_U1.X_F1 is undefined
ERROR -- Subcircuit 3F4 used by X_U1.X_F2 is undefined
ERROR -- Subcircuit 3F4 used by X_U1.X_F3 is undefined
ERROR -- Subcircuit 3F4 used by X_U1.X_F4 is undefined
but in my opinion ,i didn't use the subcircuit 3F4,becasue i use is PSPICE,what's wrong with the model?maybe the comment out is wrong?
