@g8kbv

Ah, I didn’t mean to imply that the simulator in KiCad has errors.

I didn’t understood it that way.

@g8kbv

I have not yet figured out how to use it!

I understood that you tried and failed. As didn’t know in what you had a problem I just wanted to say that there should be no very big problem as I trying it only once got it working.

@g8kbv

but how to make the simulator work with them has escaped me.

I don’t remember, but I fortunatelly did it

@g8kbv

I used to use Qucs,

I don’t know what you are saying about.

Few days ago I switched for a moment to Spice in KiCad, but I used there only resistor while your text about ‘passive’ I understand wider than only resistors.

Simple AC circuit

I supposed that may be vsin is only AC source but I have just checked and it works: [VSIN]
