\begin{itemize}
\item Name : DpgenSfft -- Static Flip-Flop with Scan-Path Macro-Generator
\item Description : Generates a n bits static flip-flop with scan-path named \verb-modelname-. The two latches of this flip-flop are static i.e. each one is made of two interters looped togethers.
\item How it works :
\begin{itemize}
\item scan : when set to \verb-one- enables the scan-path mode. Note that in scan-path mode, the wen signal is not effective
\item scin : the input of the scan-path. This terminal is different from \verb-i0[0]-. The scout is verb-q[N-i1] (in the following example this is \verb-q[31]-)
\item when wen is set to \verb-one- enables the writing of the flip-flop
\end{itemize}
\item Terminal Names :
\begin{itemize}
\item scan : scan-path mode (input, 1 bit)
\item scin : scan path in (input, 1 bit)
\item wen : write enable (1 bit)
\item ck : clock signal (1 bit)
\item i0 : data input (\verb-n- bits)
\item q : 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
\end{itemize}
