You certainly don't read mine. I have tried painstakingly to
point out all the errors and misconceptions in your mind, but you
keep repeating the same nonsense.

You don't seem to listen, that's the real problem.

That's because it's mostly nonsense, and you appear unwilling to
do anything about it.

No, no one will disagree with that. We will probably disagree
violently on who's the right person to do so however.
(BTW I know it's not me.)

Furthermore: things should me made as simple as possible,
but not simpler. (Einstein.)

Just when one thinks one has seen the worst, it gets worse.

All the nonsense about MyHDL is still there - mostly completely
wrong and I explained it several times.

Now let's move to what you try to tell us I think - how to use
object-orientation in hardware design.

I think you are totally confused. Apparently you think a class
hierarchy can be mapped to hardware hierarchy, just because both
use the word "hierarchy". Apparently you think that connectivity
can be magically implemented by subclassing. And apparently you still
don't understand why MyHDL uses generators.

Of course, you could have found this out yourself by simply
creating one small working example. But apparently it was
even too much to fire up a Python interpreter to run some
minimal checks on your code.

This what I find unbelievable: at about 1 error per line
(sometimes 2) this code seems to be written by a total newbie
in Python and object-orientation. You don't know how to
create a class in Python. You don't know how to use the
"self" argument at all. And above all, it seems you don't understand
the Python scoping rules, see the Clock example. Try to get this
to work, and you may understand what I mean with "connectivity".

Really, what were you thinking? That we are complete idiots
here and that you would get away with this? And where does
this arrogance come from that you think you should teach us
lessons in object-orientation and writing quality code?

I suggest to fix your code now, or get it off the web immediately.
Your reputation of "experienced Python programmer" is at stake.
