1.  Reviewed Patent information.

   - Chas reviewed the patent information.


2.  Reviewed minutes of the 08/16/2006 Meeting.

     During our compatibility discussion, issues with the vpiVarSelect object were discussed.
   - Ralph/JimV.  ACCEPTED (unanimous) as modified.


3.  Liaisons

   - No one reported on other meetings


4.  New business

   - vpiTagged
     Abi proposed that we should make vpiTagged a property of variables as well.
     Seems inconsistent.  Straw poll on what should we do?  No one objects.  Abi
     will work on a formal proposal.

   - Item 1570  Clarify legality of 'integer' and 'time' as DPI parameter types
     Andrzej thinks the statement could be made more general.  Ralph will rephrase
     for next time.  JimV suggested we add it to the table.  Ralph did not think
     it would fit there.  Ralph asked that JimV point out any other references that
     would be appropriate.

   - Face to Face meeting?

     Chas proposed Oct 16th and 17th in Chelmsford, MA.  Abi asked how such a meeting
     would effect voting rights.  Chas took an action to clarify voting rights with P1800.

   - Compatibility

     Reserving Var select for when we have an index that varies?  Then deprecated it for
     other cases.  What about making them both the same type, then having a property
     that says it is variable?  Chuck was trying to remove the ambiguity.  A var select
     represents something that migrates.  A reg doesn't.  What about a class variable
     to class object?  This has a lifetime.  Francoise thinks it depends on how we want
     to model class objects.  Should we try to capture local vs more global information?
     Global information can be found by parent transitions.  Differentiating between
     the two can be a good way to look at it.  Chas thinks that we should try to right
     up this concept in such a way that we can use it to guide our decision making
     process.  Chuck will take a crack at putting together such a guiding principle.

     We should consider looking at some other rules of thumb.  How closely does our
     data model match the concepts that the HDL uses?  Should try to move closer
     when possible.  Sometimes we would want to have "Cheats" or "Shortcuts"  that
     don't follow guiding principles, but make application developers lives easier.
     Chas thinks it would be good if we defined terminology or language.  Some of this
     is still tribal knowledge.

JimV/Francoise.  Meeting ended at 1:05pm.

5.  Reviewed of items with proposals.

6.  Reviewed SV-CC items with proposals (Straw poll only).

   - Chas to send everyone the frame docs for the diagrams.
   - Chuck to write a document that describes the possible solutions for the
     compatibility issues, and they're pros and cons.
   - Francoise and Bassam to continue work on assignment patterns.
   - Chas to send Michael a copy of the PAR proposal.
   - Francoise to send VCD recommendation to SV-BC.
   - Chas to ask P1800 how a face-to-face meeting would effect voting rights.

9.  Items for consideration at the next meeting (they already have proposals):

   - None.
