# The upstream makefile gets version information by invoking git. We can't
# do that. We can still use what the Makefile calls GIT_REV, because that's
# our shortcommit0 variable extracted from commit0 below.  We have to
# hard-code VER and VER_HASH here, as ver0 and verhash0.  When updating this
# package spec for a new git snapshot, clone the git repo, run make in it,
# and inspect the generated version_(has).cc to determine the correct values.

%description
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.

Together, Yosys, arachne-pnr and IceStorm provide a fully open-source
Verilog-to-bistream toolchain for iCE40 1K and 8K FPGA development.
