---++ 1. Reviewed Patent information

- Chas reviewed the patent information which can be found at http://standards.ieee.org/board/pat/pat-slideset.ppt
---++ 2. Approval of agenda

George/MIchael. ACCEPTED
---++ 3. Review [[SVCCMeetingMinutes110817][minutes]] from last meeting (Aug-17-2011)

Steve/Jim. ACCEPTED
---++ 4. Liaisons
   * Francoise indicated that the other committees have proposals for interface classes inheritance. 
      * It has an impact on VPI but no changes in the proposal.
   * Soft constraints 
      * Will have a minor impact on VPI.
   * DC is working on a proposal for user defined net types and creating interconnects 
      * Both have some impact on VPI.
   * Chas asked Francoise to get Mantis Items filed for the VPI portions of these proposals.
   * No other meetings to report.
---++ 5. Consent Agenda
---++ 6. Expedited Agenda Items
   * Item 3737 
      * Associative arrays issue. Need to have an empty array for any dimension that is an associative array.
      * Chas will add it to Items with Proposals section for next time.
   * Item 3069 
      * This Item's proposal would have an impact on VPI. 
         * Bassam suggested that we ask the other committee to add the VPI changes to the proposal.
         * Jim thought that the changes would be pretty straight forward.
         * Bassam thought we should avoid trying to define the semantics within the VPI, and try to focus on the syntax.
         * Francoise thought that what VPI would be returning is the results of the semantic analysis done by the compiler.
         * Jim moves to ask SV-AC to add VPI changes to the proposal. Francoise seconds. 
            * Bassam thinks that getting the other committee to do it will add some needed clarity.
            * ACCEPTED (unanimous) Chas to write a note the the SV-AC.
---++ 7. New business
   * Item 3087 
      * Arnab reported that Vitaly answered some of the questions in emails on the reflector.
      * Still 3 items left to discuss: 
         * STL vectors for open arrays 
            * Proxy layer open arrays would arrays of STL vectors
            * Pros: More natural for C++ ...etc. Language neutral
            * Cons: Performance (data marshalling needed)
            * Alternative would be an opaque handle where you can query for size, dimensions, ...etc
            * Other concern is incompatibility between two layers DPI-OO.
         * Use of pragmas vs attributes vs regular syntax to specify the various mapping to foreign languages
         * renaming unint32_t to bit_vecval_t to match logic_vecval_t 
            * Vitaly commented that we should get others opinions on that
            * Jim thought this was least controvercial so we should discuss it first
            * Alias sv_logic_vecval_t to logic_vecval_t and vice versa
            * SV, non-SV, or both are the options on the table
            * Discussed name space issues
            * Francoise pointed out that they are all aliases of unit32 anyway
            * Arnab and Arturo prefered the SV version
            * No objections to that
            * Jim will pass on the discussion as we will go with the SV version
      * Arturo also brought up having SV read the intermediate C++ header files 
         * Then the user can import them instead of having to replicate the equivalent method
         * Proposal lacks symetry right now
   * No other new business
<pre>Motion to Adjourn. Chuck/Michael. Meeting ended at 1:40pm EST.</pre>
---++ 8. Review SV-CC items with proposals:
   * Item 3022 
      * Proposal is in 3022.pdf. Need to remove the other PDF file.

      * Jim/Chuck. PASSED (Arnab abstained)
