I am trying to simulate opampMacro from Functional library and got this error.

Code:
ERROR (SFE-23): "input.scs" 23: The instance X1' is referencing an undefined model or subcircuit, f_oplv1c'. Either include the file containing the definition of f_oplv1c', or define f_oplv1c' before running the simulation.
I read here and here for similar error but not sure where I can add the path.
In CIW --> Tools --> Library Path Editor, there has already been functional library.
I also know the location of allFunc.scs which contain the definiton for `f_oplv1c'.
