--- Comment #12 from Cesar Strauss <cestrauss at gmail.com> ---
I found something suspicious. The testbench first writes values to some
signals, treating them as inputs:


Then, it reads from the same signals, as if they were outputs:


According to the cocotb testbench
the testbench is supposed to write to: *_pad__i, *_core__o and *_core__oe,
and then read from: *_core__i, *_pad__o and *_pad__oe.

The writing part seems OK, but the reading part is wrong. Some of the core/pad
pairs are exchanged with respect to the cocotb testbench.
