    \item \textbf{Description} : Generates a \verb-n- bits two inputs XOR with an output power of \verb-d- named \verb-modelname-.
    \item \textbf{Terminal Names} :
    \begin{itemize}
        \item \textbf{i0} : input (\verb-n- bits)
        \item \textbf{i1} : input (\verb-n- bits)
        \item \textbf{q} : output (\verb-n- bits)
        \item \textbf{vdd} : power
        \item \textbf{vss} : ground
    \end{itemize}
    \item \textbf{Parameters} : Parameters are given in the map \verb-param-.
    \begin{itemize}
        \item \textbf{nbit} (mandatory) : Defines the size of the generator
        \item \textbf{drive} (optional) : Defines the output power of the gates
        \begin{itemize}
            \item Valid drive are : 2 or 4
            \item If this parameter is not defined, it's value is the smallest one permitted
        \end{itemize}
        \item \textbf{physical} (optionnal, default value : False) : In order to generate a layout
        \item \textbf{behavioral} (optionnal, default value : False) : In order to generate a behavior        
    \end{itemize}
    \item \textbf{Behavior} :
\begin{verbatim}
nq &lt;= i0 xor i1
