NAME

6       DPGEN_SFFT - Static Flip-Flop with Scan-Path Macro-Generator
7

SYNOPSIS

9       #include  <genlib.h>
10
11       void GENLIB_MACRO (DPGEN_SFFT, char *modelname, long flags, long N);
12

DESCRIPTION

14       Generate  a N bits static flip-flop with scan-path named modelname. The
15       two latches of this flip-flop are i.e. each one is made of two  intert‐
16       ers looped togethers.
17
18       How it works :
19
20       · scan  when set to '1' enables the scan-path mode.  Note that in scan-
21         path mode, the wen signal is not effective.
22
23       · scin : the input of the scan-path. This terminal  is  different  from
24         i0[0].
25
26         The scout is q[N-1] (in the following example this is q[31]).
27
28       · wen when set to '1' enables the writing of the flip-flop.
29
30   TERMINAL NAMES
31       1. scan : scan-path mode (input, 1 bit).
32
33       2. scin : scan path in (input, 1 bit).
34
35       3. wen : write enable (input, 1 bit).
36
37       4. ck : clock signal (input, 1 bit).
38
39       5. i0 : data input (N bits).
40
41       6. q : output (N bits).
42
43       7. vdd : power.
44
45       8. vss : ground.
