TPSI3050-Q1 PSPICE simulation error

Hello Tejasri, 

Thank you very much for reaching out to us with these questions. 

This error message could be resolved by adding these missing components to your LTSpice library. However, I would strongly encourage to use PSpice for TI simulation. This simulator tool is from the cadence library and come withs preinstalled libraries reflecting many of the TI components. Essentially, TPSI3050-Q1 might be already pre-installed in the library and it is as easy as searching and drop the component. The simulator is very easy to use and we have multiple tutorial videos to help with any challenges.

Let us know if this answers your questions.

Hello Francisco,

Can you please send us that missing parts, so that we can simulate in LTspice.

Thank you,
Tejasri.

Hello Francisco,

if available, can you share the unencrypted LTspice model of TPSI3052-Q1. it will be helpful for simulation.

Thank you,

Tejasri.

Hello Tejasri, 

Unfortunately we do not support LTspice. The model available online for our device are unencrypted and it is possible to read them into LTspice. I believe that there are some online documentation from LTspice to help importing these models. The missing parts are library components which need to be added to your libraries. 

I have ran the simulations using PSpice for TI and it is very easy to obtain results. I recommend downloading from the following link and trying the simulations.

Hello Francisco,

Thank you for your suggestions.
I have downloaded the pspice and tried simulation.
Getting error : ERROR(ORPSIM-15461): Incorrect number of interface nodes for X_U1.X_U1_UPRIM_UMODE_U134. multiple errors in the same way...
Attaching connected circuit. please let me know how to resolve this issue. please send us simulation files if already exists if possible. it will be helpful because we are using this part in our circuit.

Thank you,

Tejasri.

Happy New Year! One of our experts will be back in office after the holidays and answer your questions. Thank you! 

Hello Tejasri,

I'll provide an update here tomorrow (1/5), please wait until then.

Hello Tejasri,

The following zipped project works for me. e2e-suma-3052.zip

Make sure you're referencing the following library for TPSI3052-Q1. slvmdv1b.zip

Settings for the following:

Make sure to ONLY have nom.lib and tpsi3052.lib files in the library:

Hello Tejasri,

Have you tried using the provided project files and can you confirm your simulation settings are the same? Multiple "Incorrect number of interface nodes" errors is likely due to conflicting library files, can you please share a screenshot of your configuration files under simulation settings?

Hello Chen,

Please find my attached screenshot of library files.
If possible, can we have a short call or meeting to solve this issue because we need to fix this issue soon since project timeline is reaching.
Please do the needful.

 Thank you,

Tejasri.

Hello Tejasri,

I sent a private message to setup a meeting.

Hello Chen,

My mail id: yadalatejasri@tataelxsi.co.in
Suma mail id: suma.d@tataelxsi.co.in

And our time zone is IST (India Standard Time) - (GMT+5:30). Please try to schedule a meeting tomorrow. (09-01-2023). It will be helpful.

Thank you,
Tejasri.

Hi Chen,

I followed your steps and done the process.

At step 3 (Browse \...\slvmdv1b\release\ to find "tpsi3052.lib" file and select "Add to Design")

we are not able to see the file as you shown, we are seeing spice lib file as below.



Please comment on this.

Thank you,

Tejasri.

Hello Chen,

Thank you so much for supporting. Now we are able to simulate without errors in the pspice.

Will it be possible to run the same IC without error in LTspice because we are simulating complete circuit in LTspice.

Below is the error coming in LTspice.

It will be helpful if you support to solve this issue in LTspice also.

Thank you,

Tejasri.

Hello Tejasri,

TI does not support simulation in LTSpice. These models have been created for and verified with PSpice for TI:
