---+ P1076 February 21, 2013 Meeting Minutes
---++ Attendees:
   * Main.JimLewis * Main.PeterFlake * Main.JarekKaczynski *
---++ Agenda:
   * Review VHDL-2008-Performance remaining list items
   * Review VHDL-2008-MP remaining list items
   * Review Accellera TC remaining list items
   * See these items in the [[http://www.eda.org/twiki/bin/view.cgi/P1076/Vhdl2019CollectedRequirements][collected requirements list]]

---++ Performance List
   * Perf 6: Remove deprecated constructs: Not practical. Reject
   * Perf 7: Clocks and Zero Delay ordering of signals. Reject
---++ Accellera TC List
   * SAB 3 and 4 subsumed by Random Simulus proposal
   * SAB 5, 6, 7, 8, 9, and 10 subsumed by Functional Coverage proposal
   * SAB 15: Semaphore data structure. Implement in a library. 
      * Provides: New(#keys), Get(#keys), Put(#keys), Try_Get(#keys)
      * Use Protected type is the key counter & implement the rest using regular functions and procedures.
      * try_get is a function, the others are procedures.
      * New returns the handle to the object - could be an integer index value
      * What do we need it for? Multiple items trying to use one resource. Software - network access to a printer
      * Typically only one key. Default for put and get is 1 key.
      * Waiting queue is first in, first out.
      * Should be deterministic.
   * Perf 9: Remove incremental port binding, groups, pulse rejection limit: reject
   * Perf 10: Remove guarded blocks and signals: reject
   * Env 2, 3: DPI Proposal
   * Env 1, 4: Foreign / Cross Language Model Instances 
      * Type mapping per DPI proposal
      * Formalize what tools are already doing.
      * Action item: Jerry and Cliff to collaborate on this with Peter
      * What types need to be exchanged between SV and VHDL?
   * Env 6: Extended HW functions like DW (mux, decoders, adders). Do as libary.
   * Env 8: Macros 
      * Can be very complicated. Esp for debuggers
      * In C a macro can replace the word "begin" with "{"
      * Macro is alot like a subprogram with anonymous types on the interface
   * Env 9: Conditional compilation: Have proposal without agreement on it.
---++ Action Items:
   * Jerry, Cliff, Peter to collaborate on ENV 1, 4
---++ Review and Approve Meeting Minutes:
   * Motion: Peter 2nd: Jerry
---++ Next Meeting Date (proposed):
