Hey hugo m thanks for the feedback but I regret that the simulator can only be reset and cannot be stopped once it has started.

In the meantime, there's a potential workaround available. You can consider incorporating a "push button switch" or "spst switch" (you can find these in the library) along your circuit to cut off the simulator manually. This can provide you with a means to stop the simulation as needed.

I will still move this ticket to our feature request system to ensure that your feedback reaches our team. Thanks!
