ICEBOX_VLOG(1)

💖 ICEBOX_VLOG 💖

okay so bestie, welcome to icebox_vlog from section 1 of the manual — it's giving ✨bitstream whisperer✨ and honestly? iconic.

---

🌸 NAME 🌸

icebox_vlog — convert bitstream in .txt format to verilog

---

🎀 SYNOPSIS 🎀

icebox_vlog [options] [bitmap.txt]

---

🦋 DESCRIPTION 🦋

(the original page literally spells this heading "DESCRIPTIOIN", no thoughts, we love her anyway 💀)

So here's the tea: this tool takes a bitstream that's already in .txt format — and by "already" I mean you ran it through iceunpack first, that's the whole prerequisite — and turns it into a Verilog representation. That's it. That's the job. Lowkey a glow-up for your bitstream. 💅

✨ OPTIONS ✨

• -s — strip comments from output. bye bye commentary 👋
• -S — strip comments about interconn wires from output. same energy but specifically the interconn wire commentary, not all of it, ok? read the flags carefully bestie 🫶
• -l — convert io tile port names to chip pin numbers. numbers era 🔢
• -L — lookup symbol names, using the .sym statements in the input file. she's reading the receipts 📖
• -n <module-name> — the name for the exported module. default is "chip" if you don't say anything. no cap.
• -p <pcf-file> — use the set_io command from the pcf file you point her at.
• -P <pcf-file> — like -p, except it enables some hacks for pcf files created by the iCEcube2 placer. yes, hacks. we said what we said 🔥
• -c — collect multi-bit ports. group chat behavior, fr fr 🫂
• -R — enable IeRen database checks. (that's IeRen with the capital R, we do not lowercase her name 💜)
• -D — enable exactly-one-driver checks. one driver, one car, exactly. no carpooling. 🚗
