[sv-cc] Proposed resolutions for 2-28 meeting

I have attached an e-mail that evidently didn't make it
through the sv-cc reflector yesterday -- at least it
didn't come back to me.
 
Regards,
Jim Vellenga

Charles,

I would like to propose the following two resolutions to be considered 
in Friday's meeting, and voted on, provided we have a quorum.

1) Resolved:  That the 2008 version of the standard shall not require 
implementations to track or provide notice of the "last HDL dereference 
event" for a class object or for any of its automatic data members, and 
shall not specify an optional mechanism for doing so.

2) Resolved:  That a simulation restart shall free all VPI handles 
(terminate all handle lifetimes), whether transient or not, except for 
cbStartOfRestart and cbEndOfRestart callback handles.

I think if we can agree on 1, then we can stop arguing about garbage 
collection algorithms and take that whole part of the discussion off 
the table.  And we seem to be close to agreeing on this anyhow.

As for number 2, I want to do this as part of confirming that a handle 
lifetime is a matter of a contract between an application and the VPI 
layer.  The VPI layer is free to reuse the same value for the same 
object after the restart, but we would be saying the an application 
cannot count on any handle continuing to have the same meaning or even 
any meaning.

If we can agree on 2, I will happily update the proposal to say so.

Regards, 
Jim Vellenga
