SPICE simulation. Can not setup voltage source

When running a SPICE simulation in Fusion 360 (Operting point) all Voltage is 0 Volt.

When trying to setup analog voltage source the following error appears:

You must select a part with SPICEPREFIX attribute value of V or I to use this feature. Use MAKESPICE to make changes.

I do not know where to find MAKESPICE or how it works.

Can you help me with this issue?

Thanks in advance.

Hello @arsvivendi1234,

I hope you're doing well. Have you place a voltage source from the ngspice-simulation library? The error would seem to imply that you don't have a source in the design to stimulate the circuit. I would start there, the error is a little misleading since you don't usually access the MAKESPICE command directly.

Let me know if there's anything else I can do for you.

Hello Jorge,


the voltage source from the ngspice-simulation library works. 

Thank you for the advice!
