SystemModel["Modelica.Clocked.BooleanSignals.NonPeriodic.BooleanChange"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This block is a synchronous version of
Modelica.Blocks.Math.BooleanChange.
It uses previous
instead of the implicit pre
of
change
to set the Boolean output y
to
true
when the boolean input u
changed. Thus, it's
logic is:
if firstTick() then y = false; else y = not (u == previous(u)); end if;
This block might be superfluous and replaced by
Modelica.Blocks.Math.BooleanChange
when the semantics
of change
are relaxed and well-defined for
clocked discrete-time partitions.
