DPGEN_DFF(3) Dynamic Flip-Flop Macro-Generator

SYNOPSIS

#include <genlib.h>

void GENLIB_MACRO (DPGEN_DFF, char *modelname, long flags, long N);

DESCRIPTION

Generate a N bits dynamic flip-flop named modelname. The two latches of this flip-flop are dynamic, i.e. the data is stored in a capacitor.

How it works :

  • wen when set to '1' enables the writing of the flip-flop.

TERMINAL NAMES

1.
wen : write enable (1 bit).
2.
ck : clock signal (1 bit).
3.
i0 : data input (N bits).
4.
q : output (N bits).
5.
vdd : power.
6.
vss : ground.

EXAMPLE

GENLIB_MACRO(DPGEN_DFF, "model_dff_32"
                      , F_BEHAV|F_PLACE
                      , 32
                      );
GENLIB_LOINS( "model_dff_32"
            , "instance1_dff_32"
            , "wen"
            , "ck"
            , "i0[31:0]"
            ,  "q[31:0]"
            , "vdd", "vss", NULL
            );
