\section{{\tt E}: Voltage Controlled Voltage Source}
%------------------------------------------------------------------------
\subsection{Syntax}
\subsubsection{Device}
\begin{verse}
{\tt E}{\it xxxxxxx n+ n-- nc+ nc--} {\it value}\\
{\tt E}{\it xxxxxxx n+ n-- nc+ nc--} {\it expression}\\
{\tt .VCVS} {\it label n+ n-- nc+ nc--} {\it expression}
\end{verse}
\subsubsection{Model (optional)}
\begin{verse}
{\tt .model} {\it mname} {\tt TABLE} \{{\it args}\}
\end{verse}
%------------------------------------------------------------------------
\subsection{Purpose}

Voltage controlled voltage source, or voltage gain block.
%------------------------------------------------------------------------
\subsection{Comments}

{\it N+} and {\it n--} are the positive and negative element (output) nodes,
respectively.  {\it Nc+} and {\it nc--} are the positive and negative
controlling nodes, respectively.  {\it Value} is the voltage gain.

You may specify the {\it value} in any of these forms:

\begin{enumerate}
  
\item
A simple value.  This is the voltage gain.
  
\item
An expression, as described in the behavioral modeling chapter.  The
expression can specify the output voltage as a function of input
voltage, or the voltage gain as a function of time.

\item
A {\it model}, as described in the behavioral modeling chapter.  The
{\tt table} model describes a table of output voltage vs. input
voltage.

\end{enumerate}
%------------------------------------------------------------------------
\subsection{Probes}

The standard probes for all basic elements are all available.  See the
{\tt print} command for documentation.
