I`m trying to simulate this part on PSpice V17.7 as a buffer circuit but couldnt get any leads on it. Can someone help me?

Hi Devesh,

We support simulation issues in TINA-TI or Orcad (cadence) simulators. Would it be possible for you to try this in TINA-TI? You can download the software from http://www.ti.com/tool/TINA-TI.

For additional training resource please refer to: https://training.ti.com/zh-tw/tina-ti-video-training-series

Devesh,

Does "couldn't get any leads" mean that the op amp in P-spice has no connection point for input output and supply?

TI Tina is downloadable tool that would have leads. https://www.ti.com/tool/TINA-TI

Hi Devesh,

Are you using OrCAD Pspice simulator? If so, you need to first make a symbol for the Pspice model using "Model Editor" (you will have to first change the file extension from .cir to .lib). The "Model Editor" will give out a .olb file, you need to add this to your library. After this you should be able to use this op amp symbol in your buffer circuit configuration.

Please let us know if you've any questions.

Hello Bala Ravi,

Thank you very much for the suggestion.I work with Orcad simulators so I would appreciate if it could get resolved in the Orcad domain.I would try the Tina-ti later after i get this working.

Thank you

Thank you Ronald Michallick for responding. The meaning of "Couldnt get Leads" is i`m not able to get the device to simulate in the ORCAD pspice. I have .olb file with me and i`m trying to simulate it(realized I coouldnt do it with that) .So, I started looking for the .lib file of the LM358P or LM358B - this is the one with the dual opamp configuration. I couldnt find the .lib file as of yet. So if TI has the .lib file I can use it to simulate in ORCAD.

Thank you

Hello Bala Ravi,

I`m looking as to how to change file extension from .cir to .lib. Is it just changing the name of the extension?

Hi Devesh,

Yes, you just need to right click on the file and change ".cir" to ".lib". This will allow the "Model Editor" to recognize this as a SPICE file.

Please let us know if you've any other questions.

Best Regards,

Bala Ravi
