2485:

Surrendra: Will add the indefinite articles for the sentence as

        requested in the friendly amendment, then Dmitry will mark it

        resolved.

2558:

John: Suggested adding a reference to 6.21

Surrendra: Will add this reference, then Dmitry will mark it resolved.

2412:

John: Proposal had changed "otherwise" to "if used outside an assertion"

     Felt that "otherwise" was still needed to show the priority of the

     different rules.

Anupam:    Will Make the text read: "Otherwise, if used outside an assertion"

John: Change "Unclocked sequence" to "sequence"

     You infer a clock which could apply to this part of the sequence.

     Inferred clock will not apply if sequence has a clock.

     Wants text to be more general.

Anupam: Will make the change.

Dmitry: Other comments: Text says "actual" for actual arguments

Anupam: Will change "actual" to "actual argument"

Dmitry: Text mentions sequences passed as arguments to modules.

     What about interfaces and programs?

     What about tasks and functions?

Anupam     Anything other than checker

     inference should be done in context of where it is passed.

Anupam: Has already made the grammar changes suggested by Ben.

Scott:     Feels his comments have been addressed.

Eric: His comments are the same as others. Anupam has taken care of them.

Anupam: Will upload new proposal today.

Issue resolution/discussion

2938

Eric: Has uploaded a new proposal. Adds new example.

Scott:     Fine with it.

Dmitry:    Will call for an e-mail vote

Dmitry: NOte: Don't do paragraph indentation

Eric: Will fix indentation

2095

Tom: Mantis item asks for explanation and example of using "dist" in

     a disable iff statement. Does anyone have an example?

Ed:  LRM does define distributions on page 375

John Fundamental problem with interpreting dist as inside

Ed:  It's defined explicity by LRM. Would have to change definition.

John: Consider case where x is one bit  x dist {0:=30, 1:=70} would be

     always true.

Ed:  Yes, that's how it is defined.

Ben: Seems like distribution should be interpreted as the value of the

     expression, with instructions to the random simulator about how often

     to generate each value.

Dmitry     Suggest opening new mantis item for this.

Tom  Will open new mantis item.

John Mantis description mentions long conversation between SV-CC and other

     committees to understand the meaning of a distribution.

     Can we recover thread of this conversation? It might be helpful in

     informing our course of action.

John Don't close current one unless we're sure that disable is not

     a special case.

Dmitry:    Will hold a vote next time to discuss closing this Mantis item.

Enhancements

2751 Ben has uploaded an example of the usage of interfaces passed as

     arguments to checkers.

Meeting adjourned.
