DPGEN_ROM2(3)

💖 DPGEN_ROM2 💖

okay so bestie, welcome to the DPGEN_ROM2(3) page from the Alliance - genlib User's Manual — yes she's a library function page, she's fancy, she's in section 3, she lives in genlib.h land, and she's about to make you a whole ROM. no cap. 🎀

✨ NAME ✨

DPGEN_ROM2 — the 2 words ROM Macro-Generator. that's it, that's her whole job description, and she ate. 💅

🌸 SYNOPSIS 🌸

#include  <genlib.h>

void GENLIB_MACRO (DPGEN_ROM2, char *modelname, long flags, long N, char
*constVal0, char *constVal1);

like, that's the whole entrance. copy it exactly, don't freestyle the signature, i'm begging. 🙈

🦋 DESCRIPTION 🦋

Generate a N bits 2 words optimized ROM named modelname.

that's the vibe. you hand her a name and a size, she hands you a ROM. main character energy fr fr. ✨

🧚 TERMINAL NAMES 🧚

the terminals, in order, so you know who's who at the party:

1. sel0 : address of the value (input, 1 bits).
2. q : the selected word (output, N bit).
3. vdd : power.
4. vss : ground.

lowkey iconic lineup ngl — one address bit in, N bits of word out, plus the power rails doing their lil thing. 🫶

🌈 BEHAVIOR 🌈

here's the whole personality, in glorious code:

q <= WITH sel0 SELECT
     contsVal0  WHEN B"0",
     constVal1  WHEN B"1";

(and yes, that spelling up there is exactly how the original wrote it — i'm not touching it, i don't make the rules, i just relay them faithfully. 💀)

🔥 EXAMPLE 🔥

okay so here's what it actually looks like when you use her. study the strings, they're literally strings, i cannot stress this enough:

GENLIB_MACRO(DPGEN_ROM2, "model_rom2_set1_4"
                       , F_BEHAV|F_PLACE
                       , 4
                       , "0b1010"  /* A string! */
                       , "0b1100"  /* A string! */
                       );

GENLIB_LOINS( "model_rom2_set1_4"
            , "instance1_rom2_4"
            , "sel0"
            , "q[31:0]"
            , "vdd", "vss", NULL
            );

see those /* A string! */ comments? the manpage is screaming at you that those are strings. listen to her. "0b1010" in quotes, not a number, a string, periodt. 😭
