Mosfet model doesn't work

Hello,

I have the following spice model:

If I create a Mosfet Model and past this spice code into the box and run a simulation,

I get the following error message:

"Not enough node points found!"

If I double click on the transistor and click "Modell bearbeiten (edit model)", than nothing

happens (nothing shown, no error message).

How can I use this model in Multisim 10.1 successfully?

Hi Uwe,

You have a complex MOSFET model which contains a MOSFET and all its parasitics. The MOSFET Model Maker in Multisim can only handle simple MOSFET models, not complete ones like this.

You can still create a simulatable component for this model with the Component Wizard. In step 3 of the Component Wizard, you can copy a premade schematic symbol from an existing component (such as the 2N6755). When the Component Wizard asks for a simulation model, jJust paste in the entire model into the Model Data box and give the model a unique name (such as SUM110N06). Don't use the Model Maker. When the Component Wizard presents you with the pin mapping table, assign pin 1 to the drain, 2 to the gate and 3 to the source.

That should allow you to create a simulatable model.
