arachne-pnr - Place and route tool for iCE40 family FGPAs
arachne-pnr [options] <filename>
Arachne-pnr implements the place and route step of the hardware compilation process for FPGAs. It accepts as input a technology-mapped netlist in BLIF format, as output by the Yosys synthesis suite for example. It currently targets the Lattice Semiconductor iCE40 family of FPGAs. Its output is a textual bitstream representation for assembly by the IceStorm icepack command. The output of icepack is a binary bitstream which can be uploaded to a hardware device.
-h, --help Print this usage message. -q, --quiet Run quiet. Don't output progress messages. -d <device>, --device <device> Target device <device>.
