Thanks Luke, fixed by re-installing pyvcd.


To stop my madness of copying soc files into pinmux repo, I set up a new
schroot "libresoc-dev", and have ran "hdl-dev-repos" script to get soc and
supporting libraries.
Then I modified test_jtag_tap_srv.py to use the original import paths.

Steps I take to try to run the test:
- Open two separate terminals and call "schroot -c libresoc-dev" to get into
schroot

Terminal 1:
- cd ~/src/soc/pinmux/src/spec/
- python3 test_jtag_tap_srv.py

Terminal 2:
- cd ~/src/soc/src/soc/debug/test/
- python3 test_jtag_tap.py

Error in when running server in Terminal 1:

AssertionError

I don't know what causes Error1, but Error2 looks like it might be formal
verification error.


Am I missing something else or not calling the tests correctly?
I'd really want to see something existing work.
