Hi, All -

I have raised issue this a number of times. I don't know if it was ever
formally voted.

I still think if we are going to have these "logic" and "bit" types, that
we would be doing the Verilog and VHDL communities a favor by at least
choosing the keywords: ulogic, ubit.

In VHDL, std_logic_type is the resolved type. std_ulogic_type is the
unresolved type. I don't see a compelling reason to confuse the poor VHDL
engineers by swapping the definitions on them.

Not only that, but I am guessing the "ulogic" will kill fewer existing
designs that "logic" (same argument for "ubit" vs. "bit").

This is a relatively easy global change, one that might be less
controversial when it is addressed by the IEEE VSG.

Thoughts? Is this possible?

Regards - Cliff
