# 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.
%global ver0 0.1+203+0
%global verhash0 59750

%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 an fully open-source
Verilog-to-bistream tool chain for iCE40 1K and 8K FPGA development.
