Choosing an Approach for Simultaneous Events
When your simulation involves simultaneous events whose causality
relationships do not determine a unique correct processing sequence,
you might have a choice regarding their processing sequence. These
tips can help you make appropriate choices:
Several blocks offer a Resolve simultaneous
signal updates according to event priority option. The
default value, which depends on the block, is appropriate in most
simulation contexts. Consider using the default value unless you have
a specific reason to change it.
If you need explicit control over the sequencing of
specific kinds of simultaneous events, assign numerical event priorities
for events that you want to defer until after other events are processed.
For procedures and tips related to numerical event priorities, see Assigning Event Priorities.
In some debugging situations, it is useful to see
whether the simulation behavior changes when you either change the
value of a block's Resolve simultaneous signal updates according
to event priority option or use an extreme value for an
event priority. Experiments like this can help you determine which
events might be sensitive to changes in the processing sequence. The debugger can
also help you detect sensitivities.
For details on how the application treats simultaneous events,
see Processing Sequence for Simultaneous Events and Resolution Sequence for Input Signals.
