Is it possible to import tina-ti transistor components?

Hi, I want to simulate a circuit of my textbook, using two transistors: 2N3108 (npn) and 2N3638A (pnp).

Both of them can't be find in multisim, but can be find in tina-ti:

Is there anyway to import the transistors to multisim? Or create a new component according to the model parameters listed above picture in multisim?

Best regards.

Is there a way to get .cir output from Tina?

Hi, @aestay

Thank you for replying.

Yes, there is a way to export .cir file from tina:

Then a .cir file generated, it contains the following information:

Can you tell me what can I do with the .cir file?

Best regards.

Use the Multisim Component Wizard

STEP1_CIR.png

 

Give your component a name and purpose

STEP2_CIR.png

 

Select pin and packages

STEP3_CIR.png

 

Browse packages matching your component

STEP4_CIR.png

You can also search with expressions

 

STEP5_CIR.pngSTEP7_CIR.pngSTEP8_CIR.png

 

Map symbol pins into package

STEP9_CIR (2).png

Then put the content of the cir file inside that box

You can also use the model asistants, to create a model from individual parameters without conding directly in SPICE

STEP_12.pngSTEP11_CIR.png

 

Map model variables into symbol

STEP13_CIR.png

Give your component a Family

 

STEP14_CIR.png

Then you can find it in the User Database. Hope this can help you. The model used by Multisim is the Gunmel-Poon model. You can find lots of info about coding in spice or manage spice models in Muhammad Rashid's "Spice for Circuits and Electronics Using Pspice"
Probably you will need to provide those libraries(those .LIB lines of your model) to Multisim, try without them first

Hi, @aestay

Sincere thanks, the step by step picture which you provide is very detailed and helpful. The spice is very interesting.

Best regards.
