Hello, vendor specific models are often encrypted to be used only with their own simulator. You can check in Tina TI if this is the case by right clicking on the component and entering the macro. There could be a notice that " * Encrypted macro. Content can't be viewed.". If this is the case you cannot import the model into Multisim.

as long as you try to import a standard Spice model into Multisim it should work without issues. TI and AD/Linear are known to encrypt many of their models such that they can only be used with their own simulators, TinaTI or LTSpice.


If you have encrypted models, I'm affraid the only path is to talk to the vendors for a non-encrypted model...Maybe they are willing to offer one. If not, then you are restricted to the simulator that can work with the encrytped models.
