NAME

       DPGEN_SFFT - Static Flip-Flop with Scan-Path Macro-Generator

SYNOPSIS

       #include  <genlib.h>

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

DESCRIPTION

       Generate  a  N  bits  static  flip-flop	with scan-path named modelname. The two latches of this flip-flop are i.e. each one is made of two
       interters looped togethers.

       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_SFFT, "model_sfft_32"
			      , F_BEHAV|F_PLACE
			      , 32
			      );

       GENLIB_LOINS( "model_sfft_32"
		   , "instance1_sfft_32"
		   , "scan"
		   , "scin"
		   , "wen"
		   , "ck"
		   , "i0[31:0]"
		   ,  "q[31:0]"  /* a[31] is "scout". */
		   , "vdd", "vss", NULL
		   );
