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 :

• 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.

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.
