TLV274: PSPICE for TI fails to simulate

Jamie Shaffer1

Part Number: TLV274
Other Parts Discussed in Thread: TLV271

I am new to PSPICE for TI. I have installed the program, opened, and built a simple model using the TLV271 (as recommended here) and voltage sources on each of its inputs with the goal of confirming its output. However, when I go to run the simulation, I get the error:
ERROR(ORPSIM-15108): Subcircuit AMP_TLV27X_HIGHVDD used by X_U1 is undefined

I haven't messed around with the install files at all. I am able to view the part's subcircuit spice file, but it seems to not be connected to the symbol. How do I get this simulation working?

Hey Jamie,

Did you use the part from the integrated library?

I just ran a quick test and didn't get any simulation errors.

Could you archive your project so I may access it here? To archive...

1. .dsn file should be saved
2. File > Archive Project...
3. Make sure all the boxes are checked to not lose any info

4. May be uploaded to this post via "Insert" drop down menu >Image/File/Video

All the best,
Carolina

Yes, I used the part from the integrated library (at least, I'm pretty sure).

Archived project attached.

Also, I just accidentally opened the tlv271.obj example project that's available and ran the simulation associated with it. That model worked, so the issue must be with how the libraries are connected to my project.. I came over from LT Spice and their library management is different.

Hey Jamie,

Just to confirm, you currently have a working project using the TLV271 model from the integrated library?

Best,
Jerry

Hi Jerry,

I opened the TLV271_test.obj from the contextual menu when right-clicking the part. I just tested my project again (without changing anything) and it worked this time. Maybe all that we needed was a restart of the application.
