Jay, David et al:

The semantics document has been under review for a considerable time period.  SV-AC members were invited to review and give their feedback and as far as I know no feedback was given aside from the original semantics team.

Earlier SV-AC meetings clearly stated that the document would be brought into the LRM as an appendix and there was no objection to that plan.

The semantics were completed by renowned industry experts and it is provided for completeness and support of the LRM so there is no change, but a clear semantics definition.

David,
 
I have reviewed the LRM changes here and have 1 question (which may become an objection) and 1 definite objection.
 
First the question, did the sv-ac review and approve the addition of this appendix G as part of change LRM-356?
 
I'm aware that they had been discussing John's definition here, but it is a major addition to the LRM that I saw no vote on it for inclusion, there has certainly been no debate on the reflector for the last 2 weeks (unless I've been removed from sv-ac). Erich Marschner is our usual sv-ac representative but he is traveling in Japan and somewhat out of reach. Unless there was a specific vote to include this major addition, I would ask that it be removed.
 
Secondly, I object to the change of functionality in LRM-359. The addition of the clause "Within a scope, initial values are applied in the order of declaration".  Is not a clarification, it adds a new requirement on implementation and is not complete. Initial values are allowed to contain hierarchical names, therefore specifying the ordering within a scope is not sufficient. A complete ordering of elaboration and assignment of initial values across all scopes (including parameters, localparams and defparams) would need to be done to make this initialization deterministic. This addition is a hack that adds no determinism.

Greetings,
 
I requested from the chairs and SV champions any changes they felt were required to the Draft 6 LRM before it is released. These changes are meant to be corrections to what was provided or correct missing items.
 
I have just posted to the SV-EC web site (http://www.eda-twiki.org/sv-ec/Draft_6_Review/LRM_Issues.html) the current set of changes. These changes (and any others that are deemed by the Chairs to be appropriate) will be added to the final draft of the LRM.
 
Regards
David
