    \item Name : DpgenNbuse -- Tristate Macro-Generator
    \item Description : Generates a \verb-n- bits tristate with an complemented output named \verb-modelname-.
    \item Terminal Names :
    \begin{itemize}
        \item cmd : select ( 1 bit )
        \item i0 : input ( \verb-n- bits )
        \item nq : output ( \verb-n- bits )
        \item vdd : power
        \item vss : ground
    \end{itemize}
    \item Parameters : Parameters are given with a map called \verb-param-.
    \begin{itemize}
        \item nbit : Defines the size of the generator
    \end{itemize}
    \item Behavior :
\begin{verbatim}
nts:BLOCK(cmd = '1') BEGIN
    nq <= GUARDED not(i0);
END
\end{verbatim}
    \item Example :
\begin{verbatim}
class myClass ( Model ) :
  def Interface ( self ) :
    self._in    = LogicIn  (  "in", 32 )
    self._cmd   = LogicIn  ( "cmd", 1 )
    
    self._out   = TriState ( "out", 32 )

    self._vdd   = VddIn    ( "vdd" )
    self._vss   = VssIn    ( "vss" )
    
  def Netlist ( self ) :
      
    Inst ( 'DpgenNbuse'
         , param = { 'nbit' : 32 }
         , map  = { 'i0'      : self._in
                  , 'cmd'     : self._cmd
                  , 'nq'      : self._out
                  , 'vdd'     : self._vdd
                  , 'vss'     : self._vss
                  }
         )
\end{verbatim}
