I'm just jumping in on this thread, but if that is the conclusion
there is something fundamentally wrong.

intbv is just a hardware friendly datatype. Signal is the
type we need to do racefree communication. These types should
be complementary - they can be used together (because you
want to be able to do racefree communication with any
datatype) or separate (because the datatype are useful
for plain variables also.)
