Hello all, I would like to propose you a modification of the SimState's doLoop method. This modification will enable the user to stop the simulation after specified time of seconds since the simulation starts. The time is considered here to be the real time that the simulation runs (not the time simulated in it). There's a new parameter "-untilRT" supported. Similarly to "-until" parameter, but this one deals with the real time, so therefore "RT" suffix. Maybe someone will find it useful as I do, so I'm sharing it in an attachment. Best regards, Stefan
