TOPIC: IR 2103 Dynamic/run-time creation and destruction of components
and connectivity

This IR is clearly an enhancement request. 

ACTION: Chuck to forward to VASG chair.

TOPIC: IR 2104 Using a configuration to leave a design unbound

Peter's analysis is accepted. The IR is ISAC-Approved.

Action: Chuck to forward to VASG chair for VASG approval.

TOPIC: IR 2099 Alias declarations introduce homographs

We are exploring the solution of revising the LRM so that analias
declaration with the same designator as the named entity is not a
homograph of the named entity, and two alias declarations with the
same designator that denote the same named entity are not homographs.

Several LRM changes would be needed, including changes to 10.5 to
relax the restriction that exactly one interpretation is visible, but
to allow multiple equivalent interpretations. In analyzing the various
cases it became clear that the name of a declaration is not the same
as the type it designates. Peter again pointed out that the various
examples need to be rewritten so that the aliases in question are in
the same declarative region as the aliased objects. It appears that
this interpretation covers the desired cases adequately.

ACTION: Chuck to continue analysis.

TOPIC: IR 2101 Type conversion - implicit refers to section 8.1.2
which doesn't exist

The analysis is accepted. The IR is ISAC-Approved

ACTION: Chuck to forward to VASG chair for VASG approval.

TOPIC: IR 1012 It is unclear how Physical Literals of type TIME should
be treated when checking for conformance.

Larry has begun analysis. Time literals are globally static, but the
expectation is that conformance checking, which is primarily lexical,
must be done during analysis. A reasonable solution is to exclude
literals of type time from the allowed variations in clause 2.7.

ACTION: Larry to continue analysis
