\section{{\tt I}: Independent Current Source}
%------------------------------------------------------------------------
\subsection{Syntax}
\begin{verse}
{\tt I}{\it xxxxxxx n+ n--} {\it value}\\
{\tt I}{\it xxxxxxx n+ n--} {\it expression}
\end{verse}
%------------------------------------------------------------------------
\subsection{Purpose}

Independent current source.
%------------------------------------------------------------------------
\subsection{Comments}

{\it N+} and {\it n--} are the positive and negative element nodes,
respectively.  Positive current flow is from the positive node, through the
source, to the negative node.  {\it Value} is the current in Amperes.

All of the SPICE time dependent functions ({\tt pulse}, {\tt sin}, {\tt
exp}, {\tt pwl}, and {\tt sffm} are supported.  An additional
function {\tt generator} emulates a laboratory type function generator, for
a more convenient signal input to the circuit.
