Re: sc_start

Just for clarification...

I assume the concept of "no activity" includes "no opportunity to move time forward". In other words, if there are no pending processes, but a timed notification or wait, then the simulator should move the clock forward. Should this cause a warning or not. I would argue no. All timed events will result in some activity or eventual starvation (since something has to put the events in the queue in the first place, and conceptually with the intent some process will act on the events):

  wait(10,SC_NS);
  sc_event my_event;
  my_event.notify(10,SC_NS);

Even if no process were waiting for my_event, the act of notification is itself an activity. Hence no warning.

With the above assumptions, I agree with Philipp's proposal.
