\item Name : DpgenXnor2 -- Xnor2 Macro-Generator
|
||
|
|
\item Description : Generates a \verb-n- bits two inputs XNOR 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 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 xor i1 )
|
||
|
|
\end{verbatim}
|
||
|
|

|
||
|
|
\begin{verbatim}
|
