NAME
       DPGEN_DFFT - Dynamic Flip-Flop with Scan-Path Macro-Generator

SYNOPSIS
       #include	 <genlib.h>

       void GENLIB_MACRO (DPGEN_DFFT, char *modelname, long flags, long	N);

DESCRIPTION
       Generate	a N bits dynamic flip-flop with	scan-path named	modelname. The
       two latches of this flip-flop are dynamic, i.e. the data	is stored in a
       capacitor.

       How it works :

       o scan  when set	to '1' enables the scan-path mode.  Note that in scan-
	 path mode, the	wen signal is not effective.

       o scin :	the input of the scan-path. This terminal  is  different  from
	 i0[0].

	 The scout is q[N-1] (in the following example this is q[31]).

       o wen when set to '1' enables the writing of the	flip-flop.

   TERMINAL NAMES
       1. scan : scan-path mode	(input,	1 bit).

       2. scin : scan path in (input, 1	bit).

       3. wen :	write enable (input, 1 bit).

       4. ck : clock signal (input, 1 bit).

       5. i0 : data input (N bits).

       6. q : output (N	bits).

       7. vdd :	power.

       8. vss :	ground.

EXAMPLE
       GENLIB_MACRO(DPGEN_DFFT,	"model_dfft_32"
			      ,	F_BEHAV|F_PLACE
			      ,	32
			      );

       GENLIB_LOINS( "model_dfft_32"
		   , "instance1_dfft_32"
		   , "scan"
		   , "scin"
		   , "wen"
		   , "ck"
		   , "i0[31:0]"
		   ,  "q[31:0]"	 /* a[31] is "scout". */
		   , "vdd", "vss", NULL
		   );
