\begin{itemize}
    \item Name : DpgenDfft -- Dynamic Flip-Flop with Scan-Path Macro-Generator
    \item Description : Generates a n bits dynamic flip-flop with scan-path named \verb-modelname-. The two latches of this flip-flop are dynamic, i.e. the data is stored in a capacitor.
    \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 q[N-1] (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
