Attendees

  • Jim Lewis, Rob Gaddi, Peter Flake, Pablo Blecua

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
