Overview

icestorm-bin packages Project IceStorm into a single manylinux-compatible release artefact for Linux.

What is Project IceStorm?

Project IceStorm documents the bitstream format of Lattice iCE40 FPGAs and provides tools for working with those bitstreams. It is a foundational component of the open-source iCE40 FPGA toolchain alongside nextpnr (place-and-route) and Yosys (synthesis).

Why icestorm-bin?

Upstream Project IceStorm is source-only. icestorm-bin provides ready-to-use binaries that:

  • Run on any Linux system with glibc ≥ 2.34 (AlmaLinux 9+, Ubuntu 22.04+, Debian 12+, Fedora 37+, …).

  • Require no build dependencies — just extract and use.

  • Integrate with IVPM so downstream projects can declare a binary dependency and have PATH set automatically.
