DPGEN_DFF(3)

💅 DPGEN_DFF — the Dynamic Flip-Flop Macro-Generator ✨

ok so this is a page from the Alliance - genlib User's Manual, and bestie, it's literally about making dynamic flip-flops. let's get into it 🫶

🌸 NAME 🌸

DPGEN_DFF — the Dynamic Flip-Flop Macro-Generator. that's it, that's the name, iconic behavior 👑

---

✨ SYNOPSIS ✨

#include  <genlib.h>

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

---

💖 DESCRIPTION 💖

okay so what this does is generate a N bits dynamic flip-flop named modelname. and when we say dynamic, we mean it fr fr — both of the two latches in this flip-flop are dynamic, which means the data is stored in a capacitor. no cap, it's literally just vibing in a capacitor 🦋

How it works :

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

that's the whole mechanic bestie, that's the tea ☕

🎀 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.

six terminals, all accounted for, we love a complete roster 🌈

🔥 EXAMPLE 🔥

here's the moment you've been waiting for, the demo, the main character energy:

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
            );

a 32-bit dynamic flip-flop getting born and then immediately getting instantiated. it's giving glow up ✨

quick vibe check: those terminal names are not optional and that wen signal is the whole personality of this macro, so pls don't sleep on it 💅
