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.
Solved! Go to Solution.

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
Give your component a name and purpose
Select pin and packages
Browse packages matching your component
You can also search with expressions
Map symbol pins into package
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
Map model variables into symbol
Give your component a Family
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.

if you manage to import and simulate with success, pls give kudos (click in that yellow star) 🙂
Thanks
