   A \emph{discrete-time} variable \lstinline!vd! is a variable declared with the \lstinline!discrete!\indexinline{discrete} prefix, or a variable without any prefix that is not a continuous-time variable.
   It has a vanishing time derivative between events.
-  Note that this is not the same as saying that \lstinline!der(vd)=0! almost everywhere, as the derivative is not even defined at the events, and it is not legal to apply \lstinline!der! to discrete-time variables as they are not continuous.

   During transient analysis the variable can only change its value at event instants (see \cref{events-and-synchronization}).

   A \emph{continuous-time} variable is a \lstinline!Real! variable without any prefix that is not assigned in a \lstinline!when!-clause.
