Agenda:

Meeting Discussion

• What's Next - see PrivateDocuments file: _summary_vhdl_requirements_priority.xlsx
• March 3: 48: Protected Type: Shared Variables On Entity Interface
  • Allow shared variables.
  • ?Also allow constants? Use model?

• 51: API for VHDL Assert Statements

  • AssertApi
  • For assert can be as simple as get_assert_count(Level: Severity_Level) returns total count as an integer
  • Call back mechanism would handle this nicely - can impact purity.
  • Proposal also requires handling for textio read errors
• Arrays/composites of protected types.
  • Need some input from compiler writers as to why we currently disallow this.
  • AI talk to GHDL compiler writers about this.
  • With constraint that the array and/or composite only contains protected types.
  • With the constraint that can only reference an individual element of the array or composite
  • slicing - need for passing the array to subprogram
  • Aggregates?
• Need to get back to interfaces and integers
• Attributes for identifying clocks, reset, polarity
• Restart at line 60
