   This powerful feature of Modelica to use a nonlinear plant model in a controller would require to export the continuous-time model with an embedded integration method and then import it in an environment where the rest of the controller is defined.
   With clocked equations, clocked controllers with continuous-time models can be directly defined in Modelica.
 \item
-  Clocked equations are straightforward to optimize because they are
-  evaluated exactly once at each an event instant.
-  In contrast a standard \lstinline!when!-clause with \lstinline!sample! conceptually
-  requires several evaluations of the model (in some cases tools
-  can optimize this to avoid unneeded evaluations).
-  The problem for the standard \lstinline!when!-clause is that after \lstinline!v!
-  is changed, \lstinline!pre(v)! shall be updated and the model re-evaluated,
-  since the equations could depend on \lstinline!pre(v)!.
-  For clocked equations this iteration can be omitted
-  since \lstinline!previous(v)! can only occur in the clocked equations
-  that are only run the first event iterations.

   Clocked subsystems using arithmetic blocks are straightforward to optimize.
   When a standard math-block (e.g., addition) is part of a clocked sub-system it is automatically
