DPGEN_XNOR2(3)

💖 DPGEN_XNOR2(3) — the XNOR2 Macro-Generator, bestie edition 💖

okay so this is a page from the Alliance - genlib User's Manual, and it's all about DPGEN_XNOR2, the XNOR2 Macro-Generator. yes it's a mouthful. no we're not renaming it. let's go 🦋

---

✨ SYNOPSIS ✨

#include <genlib.h>

void GENLIB_MACRO (DPGEN_XNOR2, char *modelname, long flags, long N,
long drive);

that's the whole vibe. one include, one call. slay 💅

---

🌸 DESCRIPTION 🌸

okay so what this does is it generates a N bits two inputs exclusive NOR with an output power of drive, and it's named modelname. iconic behaviour, honestly.

Valid drive are : 1 or 4. that's it. those are the only two. don't get creative 🎀

---

🧚 TERMINAL NAMES 🧚

here's the roster, in order, no cap:

1. i1 : input.
2. i0 : input.
3. nq : output.
4. vdd : power.
5. vss : ground.

five terminals. two ins, one out, one power, one ground. the friend group is complete 🫶

---

🔥 BEHAVIOR 🔥

the whole entire personality, in one line:

nq <= not(i0 xor i1)

yes bestie that's a XNOR. it's giving "not xor". periodt.

---

💜 EXAMPLE 💜

here's what it actually looks like in the wild:

GENLIB_MACRO(DPGEN_XNOR2, "model_xnor2_32"
                        , F_BEHAV|F_PLACE
                        , 32
                        , 1
                        );

GENLIB_LOINS( "model_xnor2_32"
            , "instance1_xnor2_32"
            , "i1[31:0]"
            , "i0[31:0]"
            , "nq[31:0]"
            , "vdd", "vss", NULL
            );

first one makes the macro, second one wires it up as an instance. 32 bits of pure XNOR energy ⭐
