yyeah that will get you into a world of pain :)  i'm doing my best to
keep the unit tests up-to-date however there's simply too much for
only one full-time person to do.

0.1.  that's out-of-date.  we specifically work with the git versions,
not with old releases.  the HDL_workflow instructions - and the
dev-setup scripts - would contain that exact version (and command to
install it), if we were using it.

this is why i sent you a (private) message containing the git
repositories to clone, and pointed you at the HDL_workflow.  section
on nmigen:

mkdir ~/src
cd !$
git clone https://github.com/nmigen/nmigen.git
cd nmigen
sudo bash
python3 setup.py develop
ctrl-d

notice several things:

1. glt clone development version
2. no mention of "pip3"
3. no mention of "virtualenv"
4. use of python3 setup.py >>>>DEVELOP<<<< *NOT* python3 setup.py >>INSTALL<<

if you absolutely insist on using pip3, the same effect as python3
setup.py develop can i believe be achieved with something like "pip3
install ." (notice and observe that the fullstop there is not a
sentence fullstop, it is part of the command and represents the
current working directory).

i really do not like pip3 due to the security implications (no GPG
signing of packages, no web of trust, pypi.org website becomes a
high-priority phishing and hacking target *yes this has actually
happened*) as it results in arbitrary untrusted code download and
execution.

anyway.

yes.

use latest clone, not v0.1.  it's guaranteed not to work.
