Elapsed time since beginning of test step
elapsed_time = duration(
returns the elapsed time in
timeunits for which the condition has been
true. The condition is a logical expression. The
elapsed_time is reset when the test step is re-entered or when the
condition is no longer
true. If you omit
the elapsed time defaults to seconds.
Valid time units are:
sec — seconds
msec — milliseconds
usec — microseconds
Specify the duration after 100 msec from the time when
than 50 last became true.
duration(x > 50,msec) > 100
duration statements can be used in the Test Sequence and Test
Assessment blocks and in Stateflow® charts.
In Stateflow charts,
duration statements can be associated only with a
single state. You cannot use a
duration on a transition that has more
than one source state connected using a junction.
