Information

This block is a synchronous version of Modelica.Blocks.Math.IntegerChange. It uses previous instead of the implicit pre of change to set the Boolean output y to true when the integer 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.IntegerChange when the semantics of change are relaxed and well-defined for clocked discrete-time partitions.
