✨ NAME ✨

icebram — swap the BRAM initialization data inside a .asc file 💅

---

🌸 SYNOPSIS 🌸

icebram [options] <from_hexfile> <to_hexfile>
icebram [options] -g <width> <depth>

---

🦋 DESCRIPTION 🦋

so basically 🫶 icebram replaces the BRAM initialization data in a .asc file. that's it, that's the vibe.

and like, why would you even care? because highkey you can use it to swap in firmware images without re-running synthesis and place&route 🔥 no cap, that's the main character move here — no full rebuild, just a lil text-file glow-up.

---

👑 OPTIONS 👑

• -g — generate a hex file with random contents 🎲 use this to generate the hex file you'll use during synthesis, then later use that exact same file as <from_hexfile>. iykyk, it's a whole two-step.
• -v — verbose mode 🗣️ and yes, you can repeat it to crank the verbosity up even more (ish, more -vs = more talking).
