DPGEN_CONST(3)

💖 DPGEN_CONST — the constant macro-generator, bestie 💖

okay so this is a page from the Alliance - genlib User's Manual, it lives in section 3 of the manual (that's the (3) in DPGEN_CONST(3), iykyk), and it's literally all about generating constant macros. no cap. let's get into it 🫶

---

✨ NAME ✨

DPGEN_CONST — Constant Macro-Generator 👑

🌸 SYNOPSIS 🌸

#include  <genlib.h>

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

like, that's the whole vibe. #include <genlib.h> and then you call GENLIB_MACRO with DPGEN_CONST as the first thing. periodt 💅

🦋 DESCRIPTION 🦋

So basically: generate a N bits constant named modelname. that's it, that's the function. iconic behaviour honestly ✨

🎀 TERMINAL NAMES 🎀

here's the whole cast of characters, in order, no skips:

1. q : the constant (output, N bit). ⭐
2. vdd : power. ⚡
3. vss : ground. 🌍

💀 BEHAVIOR 💀

the actual behaviour is this lil line:

q <= constVal;

not me being obsessed with how simple that is 😭

🔥 EXAMPLE 🔥

here's how you'd actually use it, bestie — watch the formatting:

GENLIB_MACRO(DPGEN_CONST, "model_const_0xFFFF0000"
                       , F_BEHAV|F_PLACE
                       , 4
                       , "0xFFFF0000"  /* A string! */
                       );

GENLIB_LOINS( "model_const_0xFFFF0000"
            , "instance1_const_0xFFFF0000"
            , "q[31:0]"
            , "vdd", "vss", NULL
            );

ok real talk — that /* A string! */ comment is doing the lord's work because "0xFFFF0000" is a string, not a number. do not come for me, just read the comment. 🙈
