I created a Pspice part using the Spice file provided by TI. When simulating, I get the following error:
ERROR(ORPSIM-15108): Subcircuit RNOISE_FREE_0 used by X_U1.XR101 is undefined
ERROR(ORPSIM-15108): Subcircuit RNOISE_FREE_0 used by X_U1.XR105 is undefined
ERROR(ORPSIM-15108): Subcircuit RNOISE_FREE_2 used by X_U1.XR104 is undefined
ERROR(ORPSIM-15108): Subcircuit RNOISE_FREE_0 used by X_U1.XR103 is undefined
Some of the lines with the offending subcircuits are as follows:
XR109_3 23 9 RNOISE_FREE_0
XR109_4 41 9 RNOISE_FREE_0
Would 'RNOISE_FREE…' be circuits recognized by TINA (TI's software) but not by PSPICE?
Could I replace them with an equivalent?
Thanks!

Yes, I have faced similar problem while executing one of my simulation circuits using
opa4132.lib
file. I have copied all files related to OPA4132 to PSpice library but it did not help. So then in simulation settings, I have changed some limits value like (ABSTOL) and (ITL1) but still the same result.Finally, I have done something which really helped me to solve this issue. You can try these steps:
nom.lib
. Here you need to add your.lib
file. In my case it was OPA4132..lib
file and then click on "Add to Design" menu. Then click on OK.Hope it will work.
