In this example the gates of the RS do not fulfill their philosophy booleans.

Tell me, please.

This is again an oscillation problem.
To solve oscillations you need to set "Initial High State" only in one of the gates to force an equilibrium state.
If you set it in both gates it is the same situation: it will oscillate.

The weird thing is that is stops oscillating when it shouldn't.

Btw: If you want to do some kind of "random generator" it will not work in simulide.

OK (forget about randomize machine), But in the starts, many times the RS stays like this ( Initial high state 0 and 1). The internal logic should take RS to some stable situation (Forzandolo), never the two outputs equal.

Tell me, please.

It starts oscillating and at some point the simulation skips some step and leave it in an inconsistent state.

If you set "Initial High State" only in one of the gates it will start correctly (but it will fail when you push the button).
But if you set "Initial High State" in both gates it will oscillate.

Yeah, yeah. I have it clear. The last one was my mistake. I apologize. Without the randomize machine issue, it works. Thank you.

The wrong initial state when it oscillates (simulation stops in inconsistent state) is solved at Rev 1358.
Now it will just keep oscillating (if not "Initial High State" is set).
