Hi,

I tried locally, this is my local changes so far:

                (("'gowin_bba")
                 "# 'gowin_bbva")))))))
    (native-inputs (list python-setuptools python-wheel

     "The project Apycula provides tools to support development and
generating bitstreams with Gowin FPGAs.")

I'm fetching from git, and renamed the package to just 'apycula' since
it appears intended to be used as tools (commands), not as a library.
I've also reported the bug found upstream and linked it here.  Thus we
can also make propagated-inputs just inputs, since they are captured in
the command wrapper scripts.

The problem now is that to generate the chipdb files we need gowin-eda.
Since this would also enable running the test suite, I think gowin-eda
should be packaged first and added to the native inputs here:

--8<---------------cut here---------------start------------->8---

python3 -m apycula.tiled_fuzzer GW1N-1

--8<---------------cut here---------------end--------------->8---

Cayetano, could you please try packaging gowin-eda and using it here, to
get past the above issue?  And see if we can enable the test suite too!
