TLV62150A: Spice model issues

Removing my content because I was typing it up as Amod was posting :)

Thank you both so much for taking the time to answer my question - I've been running in to such odd problems with ti-pspice on my end that are just baffling. I'll run with this today / tomorrow and see how things go, I'm a little worried that my library might be corrupted. I think I'll test this by deleting the part from the schematic Amod shared and see what happens when I reinsert it from my library. 

Kevin, I did get to see the note you left via my email and I appreciate the advice on the simulation speed level setting - I was looking at that and wondering if it affected anything. When I googled it, I only found articles talking about how it helped with simulating different version files.

Sure Cameron, let us know how this testing goes. Apart from the speed level setting that Kevin suggested, you can just directly go into simulation profile and change the maximum time step to a larger value to speed up sims with a little compromise on accuracy.

Thanks,
Amod

Well team I must admit I am quite confused by this - I took Amod's simulation and it ran fine, I then removed the TLV model and placed mine from my library and it again worked properly. I then went back to my project, replaced the tlv model, but got the following result. It seemed to be working until something random happened.. the only difference I can see between our two models is an increased separation of grounds. My simulation profile of course is slightly different, but that should not be causing the aforementioned differences!

Again, I appreciate all the help! I attached my project this time - I was using the transient simulation profile.Power Project-PSpiceFiles.zip

Cameron,

I have requested the PSPICE team to take a look at your project.

Thanks,

Amod

Cameron,

Please share a valid archive.

Thanks,
JC

A valid archive? Did I zip the wrong file? 

Sorry I haven't shared a pspice project prior to this.

Files for E2E.zip

I resaved the project and confirmed this has both the OBJ and DSN file, let me know if there is something missing. I also realize I should mention I have this error when opening up my project, but not Amod's:

Archived Files for E2E.zip

I archived the files this time as well.

Thanks Cameron. I am running simulation on this file.

This merely tells you that your sim profile contains a model library file that is not inside the same folder where your project is. This is a common reason that zipped up project does not work on someone else's computer. it's a warning, not an error.

Cameron,

You have 2 pages under your schematic, "page1" and "redesign 5v/1a". Please note that schematics are the minimum entity to be simulated. Every simulation profile name contains the name of the schematic they are set for. So, if you don't need to the circuit on page 1, please delete it and try again.

Let me know if both pages should be included. There might be some undesired interactions.

Regards,
JC

Deleted the additional page, the issue persists Power Project Deleted Page.zip

Cameron,

When I tried to run the simulation, this message showed up in session log:

WARNING(ORNET-1085): Your design does not contain a Ground (0) net. You may not be able to run analog simulation on this design. To run analog simulation, your design must have at least one Ground (0) net. Use at least one PSpice Ground (0) symbol in the design. Ignore this warning, if this is a digital design.

After placing a true zero volt ground (click "Place" - "PSpice component" -> "PSpice ground"), I reset the simulation options and got this:

Hey JC,

I tried replacing my ground with the specific Pspice ground and nothing changed on my side. Did you do something more than simply replace the ground that I had in my simulation? Maybe I'm not sure what you mean by reset the simulation options, I assumed just reran the simulation.

Here's the output from my simulation log:

Cameron,

I was meant to say resetting analysis options. These are the tolerances that are set in the sim profile and they were too loose:

JC

Hey JC,

Why does that fix the problem! I mean I'm not mad that it works, I'm just very confused. 

Was something odd happening in the autocorrelation feature due to the loose tolerances?
