[sv-cc] RE: [SystemVerilog P1800 0001751]: Clarify vpiParent for part selects

Arrgh!  You've added a note, but Mantis won't let me
add a reply (apparently), now that the issue is marked
resolved.

Ordinarily, I would agree with you that I don't have
to say both.  What makes the difference here is the
context:  The object model diagram shows "indexed part
select" and "part select" as distinct objects, where
"part select" does not include "indexed part select"
as a subtype.  To me, dropping the "or indexed part
select" in this context makes it possible for the
reader at first glance think that it applies only
to the unindexed part selects.

In the text of a standard it's better to be precise
than to be economical.

Since you evidently can still add notes, could you
do me the favor of including the preceding two paragraphs
with my name?

Thanks,
Jim

]Summary:                    Clarify vpiParent for part selects
]Description: 
]With the recent clarification of vpiParent for variables and 
]nets, someone
]could ask what the parent of a part select or indexed part select.  For
]example, when someone declares
]
]  reg [0:3]{7:0] x;
]
]is the parent of "x[1][0:1}" represented by "x[1]"
]or is it just "x"?

]Issues raised:

]     Not sure where this one goes within the LRM.
]     Seems to be 36.50, but we aren't sure.

]"part-select" includes indexed part-selects unless explicitly
