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 :
- •
- 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.
