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 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

Motion to Adjourn. Chuck/Michael. Meeting ended at 1:40pm EST.

8. Review SV-CC items with proposals:

• Item 3022

  • Jim/Chuck. PASSED (Arnab abstained)
