Re: ISAC: New IR 2104 Using a configuration to leave a design unbound

Peter,
 From 5.2.1.1:
    The third form of entity aspect is used to specify that the
    identification of the design entity is to be deferred.
    In this case, the immediately enclosing binding indication is
    said to not imply any design entity. Furthermore,
    the immediately enclosing binding indication must not include a
    generic map aspect or a port map aspect.


What does "deferred" mean?  Does it mean don't ever bind this design?
Or does it mean if there is a visible entity of the name MEMIO in
the library, then feel free to default bind it?

I need the semantic, "don't ever bind this design".

Cheers,
Jim
