---++ Action Item Review

*Done before meeting*
   * [[FixedFloatUpdates][In Proposal]] Bugzilla 17 - add_carry in numeric_std as well as fixed/floating packages 
      * In the fixed point package, but not floating point package.
      * Not in numeric_std. Add for consistency?
   * [[FixedFloatUpdates][In Proposal]] - Should numeric_bit/std have resize with size_res parameter? 
      * David proposed it for consistency with the fixed and floating point packages
   * [[FixedFloatUpdates][In Proposal]] Bugzilla 262 - Fixed Generic Pkg and checking valid range
   * [[RealMatrixPackage][Real Matrix Package]] proposed change list on TWIKI as David's response to discussion

*Discussion*
   * Peter looking at modular types 
      * Why not just use ieee.numeric_bit.unsigned and expect the tools to map bit_vector based math types to integer objects internally?
      * This would also address different length integers
      * Peter to initiate discussion on reflector
   * Need more reviewers of matrix math package
   * Cliff - to update conditional expression proposal [[ConditionalExpressions]] 
      * Cliff continuing work on proposal
   * Jim - 2109 - work on Semaphores is at [[SemaphoreDataStructure]] 
      * Needs resulting proposals expanded and a reference to the open source code added
   * Closed - 2026 - Upward propagating Generics. 
      * VHDL-2008 introduces external names to constants that address this requirement.
      * There is no need to add a redundant feature.
      * Document that 2026 is closed

*Deferred*
   * Martin - 2033 - Increment operator with modulo wrap around. 
      * Proposal at [[ModularTypes]]
      * Peter to look at this too from a language design side.
   * Ryan: Arbitrary width real: see [[2012_MeetingNovember8][Nov 8 2012 meeting]]
   * Open - Multi dimensional Array restructuring: Array &lt;--&gt; Matrix Transformations [[2012_MeetingJuly19]] [[MeetingDecember15]] 
      * Matlab has built-in reshape functions
      * In VHDL - explicit vs implicit defined operator
      * David Bishop: Requiring an implicit operator could delay implementations
      * Can this be handled by anonymous types on interfaces or generics on a package?
      * Language facility for creating implicit operators?
   * Ryan - Slicing Multidimensional Arrays (FT15) maybe related to above [[2012_MeetingMay24]]
   * Jim - Mark bugzillas for which we have a proposal with that status
   * Jim - Table driven modeling via protected types [[2012_MeetingMay10]]
   * Open - technical leader for 1076.6 activities? 
      * std_logic_1164 uses 1076.6 attribute "RTL_SYNTHESIS_OFF" and "RTL_SYNTHESIS_ON"
---++ Ranking Criteria
   * Rank based on need 
      * Item needs to be fixed
      * Useful for an application
   * Rank based on complexity 
      * How hard to implement
   * Noted several items in Collected Requirements as Must Do
   * AI: Jim: Create ranking sheet.
