PSPICE-FOR-TI: TPS4811 spice error

Hi Naoyuki-san,

Are you simulating TPS48110 project on its own or with TPS48111? Looks like your netlists or libraries are mixed up. TPS48110 does not have dual gate drive control hence it is missing G and INP_G controls, which TPS48111 does have. 

Thanks, 

Sarah

Hi Sarah,

Thank you for your answer. My explanataion was a little bit confused you. At first I tried TPS48110 then the error "Pin G in template not found on U4" and "Pin INP_G in template not found on U4". Therefore I switched simulation device from TPS48110 to TPS48111. After that I tried TPS48111 simulation then net list error. 

Hi Naoyuki-san, 

No problem. Both of these model should have sperate libraries. Are you getting these from Ti.com? Are you using TI PSPICE? 

If you are starting with TPS48110 and receiving error related to missing INP_G and G pins then something is wrong with expected netlist and libraries. 

Thanks, 

Sarah

Hi Sarah,

Yes, I got these files from TI.com and I'm using TI SPCICE. I will try again and let you know the result. 

Thanks,

Ok. 

Thank you,

Sarah

Hi Sarah,
I tried again the simulation with PSPICE for TI, but I have same issue that connection error, see attached files. Can you let me know how to solve this error?

Hi Naoyuki-san, 

Let me take a look at model. Please be patient as this model will take time to debug. 

Thanks, 

Sarah

Hi Sarah,

Sorry to late reply. I will send my model data without ".dat" file because of size. Please see attched file. If you need more files, please let me know.

Thanks,

Hi Naoyuki-san, 

Have you made changes to these files? I verified the fresh files on ti.com do not have any errors when running the start up sim. 

Thanks,

Hi Sarah,

Thank you for confirming my files. I have not changed these files so I wonder your result. I will re-install TI PSPICE then retry sim.

Thanks,

Ok. Let me know if you still have issues.

Thanks, 

Sarah
