\begin{itemize}
    \item Name : DpgenNor3 -- Nor3 Macro-Generator
    \item Description : Generates a \verb-n- bits three inputs NOR with an output power of \verb-drive- named \verb-modelname-.
    \begin{itemize}
        \item Valid drive are : 1 or 4
    \end{itemize}
    \item Terminal Names :
    \begin{itemize}
        \item i0 : input (\verb-n- bits)
        \item i1 : input (\verb-n- bits)
        \item i2 : 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
        \item drive (optional) : Defines the output power of the gates\\If this parameter is not defined, the \verb-drive- is the smallest one permitted.
    \end{itemize}
    \item Behavior :
\begin{verbatim}
nq <= not ( i0 or i1 or i2 )
\end{verbatim}
    \item Example :
\begin{verbatim}
class myClass ( Model ) :
  def Interface ( self ) :
    self._in0   = LogicIn  ( "in0", 32 )
    self._in1   = LogicIn  ( "in1", 32 )
    self._in2   = LogicIn  ( "in2", 32 )
    
    self._out   = LogicOut ( "out", 32 )

    self._vdd   = VddIn    ( "vdd" )
    self._vss   = VssIn    ( "vss" )

         , map  = { 'i0'  : self._in0
                  , 'i1'  : self._in1
                  , 'i2'  : self._in2
                  , 'nq'  : self._out
                  , 'vdd' : self._vdd
                  , 'vss' : self._vss
                  }
         )
