NAME¶

DPGEN_DFF - 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
            );
