Meeting Discussion

• Next Revision
• Ideas from Email
  • Granular control over numeric std warnings / error / failure
    • Sense is that able to promote to FAILURE, but not on by default.
      • If put in a protected type, can turn it on or off in another package
      • Need warning if there are multiple conflicting calls to settings.
        • Because different packages may try diff settings.
    • Integer truncation
      • A5_uv + 254 ; -- Warning? should be Failure?
      • for i in 1 to 100 loop A4_uv := X"0" + i ; -- Warning when i > 16 -- fails to meet intent of VHDL - FAILURE
      • for i in 1 to 100 loop A4_uv := X"0" + (i mod 16) ;-- no warnings
      • Rob: unsigned - expect modular behavior
      • 1 improvement - signal errors in "+" rather than "to_integer"
      • Alternate - to_integer uses new 2019 calls stack information
    • Unsigned * Integer
      • Size of result?
      • A_uv * 3D"5" ;
  • 0 bit numeric types - AI Ryan
  • Automatic Port/Parameter Association Lists
