TPS7A39: TPS7A3901 Model For Tina Simulation

Hi Dean, 

Will you help to re-add the picture using the toolbar via "insert/edit media"?

Hi Dean, 

Please allow 2 business days for me to investigate this and it seems to me that the model file needs to be revised.

Hi Jason,

Was this completed?

I checked again both models still have issues.

Hi Dean, 

I looked into the line with the problem, and I could not find a solution. The syntax of having the if statement on line 68 seems fine to me. I think TINA is having some compatible issues on the netlist file with if statement. The same netlist file works for PSPICE for TI. Is it possible for you to run the simulations using Cadence PSPICE or PSPICE for TI?

Hi Jason,

Is PSPICE FOR TI a replacement for tina-ti?

Regards,

Dean

Hi Jason,

The *.LIB file doesn't work in PSpice for TI either.

Hi Dean, 

If you use PSPICE for TI, you don't have to use the unencrypted model. Instead, you may use the PSPICE model directly, and please try this one and let me know if it works for you. I was able to run sims using the PSPICE model below.

Hi Jason,

As per above Jan 27, 2021 2:01 PM I checked both models....

Let me verify it again, and I will get you an answer by EOB.

Hi Jason,

Okay let me know when I should be able to try re-downloading and testing the *.LIB file.

Regards,

Dean

Hi Jason,

*.obj file works but the *.lib does not work.

Do you no longer support *.lib Files even though they are contained in the *.Zip file mentioned?

Regards,

Dean

Hi Dean, 

I was actually trying to fix the problem in the lib file but failed. It's like fixing a PCB layout without a schematic. The normal solution for the .lib fix is to generate a new netlist from the original PSPICE development file with the schematics and sub-blocks. This project only contains final output files for the Cadence PSPICE simulator ( PSPICE for TI) and the original development did not have all the schematic level design required to regenerate the netlist. 

As for now, the solution is to run the simulations in PSPICE for TI.
