\subsubsection{Name}
Reg -- Easy way to instantiate a register
\subsubsection{Synopsys}
\begin{verbatim}
netOut <= netCk.Reg ( netIn )
\end{verbatim}
\subsubsection{Description}
This method is a method of net. The net which this method is applied to is the clock of the register. The net given as parameter is the input net. The method returns a net : the output net.\\
\indent Note that it is possible to change the generator instanciated with the \verb-SetReg- method.
\subsubsection{Example}
\begin{verbatim}
class essai ( Model ) :
def Interface ( self ) :
self.A = SignalIn ( "a", 4 )
self.S = SignalOut ( "s", 4 )
self.Ck = CkIn ( "ck" )
self.Vdd = VddIn ( "vdd" )
self.Vss = VssIn ( "vss" )
def Netlist ( self ) :
self.S <= self.Ck.Reg ( self.A )
\end{verbatim}
\subsubsection{Errors}
Some errors may occur :
\begin{itemize}
\item \verb-[Stratus ERROR] Reg : The input net does not have a positive arity.-\\The input net must have a positive arity.
\item \verb-[Stratus ERROR] Reg : The clock does not have a positive arity.-\\The clock must have a positive arity.
\end{itemize}
