arachne-pnr

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 [0] synthesis suite for example. It currently targets the Lattice Semiconductor iCE40 family of FPGAs [1]. Its output is a textual bitstream representation for assembly by the IceStorm [2] icepack command.
