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_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_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
