H A Dscheduler.hhdiff 13125:2488fd19b643 Tue Aug 28 02:18:00 EDT 2018 Gabe Black <gabeblack@google.com> systemc: Clamp the time of events to the present.

If systemc attempts to schedule an event in the past, schedule it for
right now instead. Still preserve the difference between delta and
timed events. This scheme doesn't really make a lot of sense (why not
just disallow scheduling events in the past?) but this will approximate
what I think the correct behavior is. What's probably supposed to
happen is that events in the past are executed from most past to most
present until they catch up with now, and then now advances as normal.
Our approach is simpler, but won't preserve ordering between multiple
events scheduled in the past.
