NAME
DPGEN_DFFT - Dynamic Flip-Flop with Scan-Path Macro-Generator
SYNOPSIS
#include <genlib.h>
void GENLIB_MACRO (DPGEN_DFFT, char *modelname, long flags, long N);
DESCRIPTION
Generate a N bits dynamic flip-flop with scan-path named modelname. The two latches of this flip-flop are dynamic, i.e. the data is stored
in a capacitor.
How it works :
o scan when set to '1' enables the scan-path mode. Note that in scan-path mode, the wen signal is not effective.
o 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]).
o 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.
