I see the Convergence failed! message in the bottom left and the simulation is unable to run:

And did you find the reason? Is it a bug or a problem in the circuit ? Le ven. 6 déc. 2024 à 21:21, Martin ***@***.***> a écrit :

Ok I see it on windows.

I put a delay buffer after the comparator and that seems to fix it. I'm still not sure if the circuit is working properly though.

The comparator in this simulator is infinitely fast which is not very realistic and can cause convergence issues.
