DPGEN_SFFT3
Static flip-flop with scan-path macro-generator
Usage
#include <genlib.h>
void GENLIB_MACRO (DPGEN_SFFT, char *modelname, long flags, long N);
Overview
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.
