ICEUNPACK(1)

💖 ICEUNPACK 💖

okay bestie, so the manual name is iceunpack and it lives in section 1 of the manuals (that's the "type it in your terminal" section, iykyk). Let's get into it 🫶

---

✨ NAME ✨

iceunpack — unpacks binary bitstreams for Lattice FPGA into a readable .txt file ✨

like. it takes the crunchy binary blob and hands you back something you can actually read. iconic behavior.

---

🌸 SYNOPSIS 🌸

iceunpack [options] [input-file [output-file]]

---

🦋 DESCRIPTION 🦋

This tool can be used to unpack binary bitstreams for Lattice FPGA. It is part of the icestorm project.

that's the whole vibe. it's a teammate in the icestorm project, and its job is literally just "binary in, readable text out". no notes. 💅

🎀 OPTIONS 🎀

• -u — unpack mode. and lowkey? it's implied when you call it as iceunpack, so you usually don't even have to say it. she already knows. 😌
• -v — verbose. repeat it to increase verbosity. yeah like the more times you say it the more she tells you. 🗣️
• -b — write cram bitmap as a netpbm file.
• -f — write cram bitmap (fill tiles) as a netpbm file.
• -c — write cram bitmap (checkerboard) as a netpbm file. repeat it to flip the selection of tiles. like a little toggle, we love a toggle. 🔁
• -r — write bram data, not cra, to the netpbm file.
• -B0,-B1,-B2,-B3 — only include the specified banks in the netpbm file. pick your bank, bestie. 🏦
