OPA690: PSpice Model Issues

Part Number: OPA690

I downloaded the model for the OPA690 from the TI website.  I added the model to my design, and tried to simulate.  I used the .lib and .olb files unaltered.  When I ran the simulation, I got the following errors:

ERROR(ORPSIM-15108): Subcircuit OPA690_F9 used by X_U1.X_F9 is undefined

ERROR(ORPSIM-15108): Subcircuit OPA690_F10 used by X_U1.X_F10 is undefined

ERROR(ORPSIM-15108): Subcircuit OPA690_F3 used by X_U1.X_F3 is undefined

ERROR(ORPSIM-15108): Subcircuit OPA690_F4 used by X_U1.X_F4 is undefined

ERROR(ORPSIM-15108): Subcircuit OPA690_F6 used by X_U1.X_F6 is undefined

ERROR(ORPSIM-15108): Subcircuit OPA690_F5 used by X_U1.X_F5 is undefined

ERROR(ORPSIM-15108): Subcircuit OPA690_F1 used by X_U1.X_F1 is undefined

ERROR(ORPSIM-15108): Subcircuit OPA690_F2 used by X_U1.X_F2 is undefined

Interestingly, when I look in the lib file (unaltered), I see where the top level subcircuit uses those.  I do NOT see where they get defined.  Those additional subcircuits all have entries in the OLB file, though.

Seems to be similar to the problem described here:  e2e.ti.com/.../268784

    Additional Information: using PSpice v17.2-2016

    EDIT: resolved the issue.  Apparently, in 2021, PSpice still does not like spaces in paths.  Interestingly, the tools showed a relative path to the library file (which did not have any spaces).  However, the absolute path of the lib file DID have spaces.  Changed the path, and now the simulation (and model) works as expected.
