PSPICE-FOR-TI: How do I load in the full TI catalog?

Part Number: PSPICE-FOR-TI
Other Parts Discussed in Thread: TINA-TI, THS4551

I just installed PSpice. I wanted to see if it was easier to work with than TINA-TI.

It comes with a library of generic parts and a short list of TI components.  One of the parts it does not have is the THS-4521 FDA. It has it's two bigger siblings, the 4522 and 4524. 

I hit e2e trying to see if anyone else had noticed it missing (to see what the solution was) and found a link where some engineer said that instead of using the 4521, we should be using the 4551.  I thought "hmm, maybe that's valid advice since the 4521 has been around for a while".  The THS-4551 was not in the brand new, freshly installed PSpice for TI library either. Neither is the ADS-1278. 

So clearly, the library needs a refresh.  According to the installed help (from cadence), opening Capture should trigger a refresh. Well none of the screens or panels are called "Capture" but the outdated graphic implied that I should be opening the tool for editing schematics.  Another forum post suggested doing a restart.

I searched every menu item looking for an kind of  manual trigger to "refresh the TI libraries". I did not spot one. IF it exists, where is it hiding?

I searched the list that navigating through Help->Known Problems and Solutions brings up.  That is is fairly short and none of them appear to involve a lack of inventory refresh.

I shut down and reopened PSpice.  This triggered a library update only once (on the second-ever launch). That said it had 135 new components to load in. I thought "Great!". Then I went looking and none of the missing products were added during the refresh. I tried creating a new project in order to get a whole new schematic. Those parts (and probably many many others) are missing from the tool's catalog of parts.

I'm using "PSpice for TI 2020" version 17.4-2020-S002.    It should be up-to-date.

What step(s) did I miss and how can I fix it?

Thanks,

Shawn

    Hi Shawn,

    Thanks for the feedback. You've done all the right things.

    The list of TI component in PSpice for TI does not cover the entire TI portfolio that is supported by PSpice models, however, overall it is fairy close and as you've noticed, we are added models constantly. It is possible that in certain areas the model support in the tool requires more catchup compare to others. If you want to see a model in the tool, please contact a TI field applications engineer who can request individual models added.

    The THS4551 model was published very recently and has not made it into the tool yet. You can find the THS452x model under "Amplifiers" -> "Fully differential amplifiers", or simply search "THS452". Right click on the search results will give you the option to open the published testbench.

    Thanks,
    JC
