longDescription = ''
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.
