\subsubsection{Description}
|
||
|
|
|
||
|
|
How to create and use nets.
|
||
|
|
|
||
|
|
\subsubsection{Nets}
|
||
|
|
|
||
|
|
Differents kind of nets are listed below :
|
||
|
|
\begin{itemize}
|
||
|
|
\item \verb-LogicIn- : Creation of an input port
|
||
|
|
\item \verb-LogicOut- : Creation of an output port
|
||
|
|
\item \verb-LogicInOut- : Creation of an inout port
|
||
|
|
\item \verb-LogicUnknown- : Creation of an input/output port which direction is not defined
|
||
|
|
\item \verb-TriState- : Creation of a tristate port
|
||
|
|
\item \verb-CkIn- : Creation of a clock port
|
||
|
|
\item \verb-VddIn- : Creation of the vdd alimentation
|
||
|
|
\item \verb-VssIn- : Creation of the vss alimentation
|
||
|
|
\item \verb-Signal- : Creation of an internal net
|
||
|
|
\end{itemize}
|
||
|
|
|
||
|
|
\subsubsection{Parameters}
|
||
|
|
|
||
|
|
All kind of constructors have the same parameters :
|
||
|
|
\begin{itemize}
|
||
|
|
\item \verb-name- : the name of the net (mandatory argument)
|
||
|
|
\item \verb-arity- : the arity of the net (mandatory argument)
|
||
|
|
\item \verb-indice- : for buses only : the LSB bit (optional argument : set to 0 by default)
|
||
|
|
\end{itemize}
|
||
|
|
|
||
|
|
\indent Only \verb-CkIn-, \verb-VddIn- and \verb-VssIn- do not have the same parameters : there is only the \verb-name- parameter (they are 1 bit nets).
|
||
|
|
|
||
|
|
\subsubsection{Example}

\subsubsection{Errors}
|
||
|
|
|
||
|
|
Some errors may occur :
|
||
|
|
\begin{itemize}
|
||
|
|
\item \verb-Error in LogicIn :-\\\verb-the lenght of the net must be a positive value.-\\One can not create a net with a negative lenght.
|
||
|
|
\end{itemize}
