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

#include <genlib.h>

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

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 :

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

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

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.
