I'm an italian high school teacher.
I'm newbie to MultiSim.
I'd like to simulate a PWM interface that use, among others, this two componenents that are'nt in the MS embedded libraries:
I'd like to know wich is the better and faster way to solve the issue:
I've tried the second way for the mosfet following this tutorial: http://www.ni.com/tutorial/3173/en/
But at step 6 I've received this error message:
I must specify that I'm a mechanical engineer and I teach System and Automation with limited electronic competencies.
Is there anyone that can help me?
Thanks in advance
searching for your error message I found two forum threads that could give you useful insight:
In the meantime I'll ask NI Multisim experts for advice about the most convenient way to simulate components not present in Multisim embedded libraries.
it seems you made a mistake in one of the first steps in the Component Wizard; you defined a symbol to use on the schematics having 3 pins (component symbol pins), but the SPICE code defines 5 inputs/outputs (model pins). That does not match up. I'd guess you picked a symbol with only three pins in step 3 of the wizard.
If you can't figure it out, could you please attach the component file? Otherwise I'm afraid I can't help you that much.
Hi alamanna, thansk for your reply.
I've downloaded the model directly from the ST website:
Attached to this mail the downloaded model.
Otherwise, if I look on the ST website, I can see that the component has only 3 pins:
Thanks in advance,
I had a look at the SPICE model you attached and the SPICE code itself also defines three parameters/pins (named 1, 2, and 3 in the .SUBCKT definition), so that's fine:
* MODELLING FOR STP10NK60ZFP .SUBCKT STP10NK60ZFP 1 2 3 LG 2 4 7.5n [...]
I tried the steps of importing the model into Multisim myself...
and found the cause: The comment in the first line confuses Multisim. Remove it and it works:
Edit: I am using Multisim 14.1.0. I did some further testing and found the issue being correlated to the comment containing the model name.
This is fine:

This errs out:
