history
Project history and usage
nextpnr-ice40 is the Lattice iCE40 build of nextpnr, YosysHQ's portable FPGA place-and-route tool. In the open FPGA stack it sits after synthesis: Yosys emits a JSON netlist, nextpnr-ice40 performs pack/place/route against the iCE40 architecture database, and IceStorm turns the routed ASCII bitstream into a programmable binary.
The project matters because it helped move the iCE40 flow away from one-off place-and-route tooling toward a retargetable FOSS framework. Public project material describes nextpnr as vendor-neutral and timing-driven, with iCE40 support backed by Project IceStorm and later support for ECP5, Nexus, Gowin, GateMate, and experimental back ends.
Project history
A 35C3 talk described nextpnr as the next step after Project IceStorm, replacing arachne-pnr in the open-source iCE40 flow while opening a path to multiple FPGA vendors. The 2019 Yosys+nextpnr paper framed the combination of Yosys and nextpnr as an architecture-neutral open-source Verilog-to-bitstream framework for commercial FPGAs, with iCE40 and ECP5 as hardware-proven early targets.
Adoption history
Adoption is strongest among people using small Lattice iCE40 boards, open hardware examples, CI-able FPGA builds, and education/hobbyist workflows where the vendor IDE is too heavy. GitHub showed about 1.7k stars and 318 forks on the nextpnr repository when researched, and the Homebrew API generated on 2026-04-23 reported 50 installs-on-request in the preceding 365 days for the separate nextpnr-ice40 formula.
How it is used
Package nerd usage is usually scripted: synthesize Verilog with `yosys -p 'synth_ice40 ... -json design.json'`, run `nextpnr-ice40 --json design.json --pcf pins.pcf --asc design.asc`, then use `icepack` and `iceprog` from IceStorm. The Homebrew formula encodes that relationship directly by depending on `icestorm` and using `yosys` for its test dependency.
Why package nerds care
The formula is intentionally architecture-specific rather than a monolithic all-FPGA build. That packaging shape mirrors nextpnr's build system, where `-DARCH=ice40` builds the iCE40 executable and keeps users from pulling every supported architecture database when they only need Lattice iCE40.
