\item Name : DpgenNand4 -- Nand4 Macro-Generator
|
|
\item Description : Generates a \verb-n- bits four inputs NAND 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 i3 : 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 and i1 and i2 and i3 )
|
|
\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._in3 = LogicIn ( "in3", 32 )
|
|
|
|
self._out = LogicOut ( "out", 32 )
|
|
|
|
self._vdd = VddIn ( "vdd" )
|
|
self._vss = VssIn ( "vss" )
