Agenda:

Meeting Discussion

• Review PrivateDocuments file: _summary_vhdl_requirements_priority.xlsx
• Restart at line 75
• 64: Wait Level
  • Does LRM allow expressions on in mode signal parameters? It does work for ports (6.5.6.3)?
  • If it is not the case, it seems the simplest path is to make it so.
  • Does it matter if it is a concurrent or sequential subprogram call?
• 65: Named Package Bodies
  • If not, we would could use an abstract package to implement this.
  • Do we need the capabiltiy to use both packages at the same time?
    • If this is a limited use case, could pass two abstract packages to the entity.
• 66: Unions / Variant Records
  • Need for higher functionalilty in functional coverage modeling
  • Think of sets
• 67: Expressions in bit string literal specifications (to allow parameterized sizing based on a static value - ie generic)
  • AI: Brent ask Tristan and/or Lieven why this is so hard.
• 68: Required Resolution
  • Need to look into if this is even necessary as David Koontz pointed out simulators should produce an error which would satisify this proposals goals.
  • Is this an LRM or tool issue given the LRM already indicates it is an error?
  • Need to run simulation of: process begin CLk <= '1' ; wait for 1 ps ; Clk <= '0' ; wait for 1 ps ; end process ; with simulator resoluton of 1 ns
• 69: Relax Others in aggregates
  • Forward this to Tristan and/or Lieven
• 70: Record Member Attribute
  • Introspection of the record via iteration
  • Associated with mapping within interface/bundle procedures
  • may be able to use 'simple_name
  • May be a required part of anonymous types
• 71: Bidirectional Connections
  • Linked to interface/bundle proposal
  • AI: Lieven consider this with the interface/bundle proposal
• 72: Optional Semicolon on entity interfaces
  • AI: Rob integrate the other proposal into this.
• 73: Function Knows Vector Size
  • Too much complexity without simplifying the code - adds discontinuities to the language.
• 74: Cross language Instances
  • Can this be part of the DPI proposal?
  • AI: Peter Flake
