Meeting Discussion

• Review of 2019 LCS / proposals finished last meeting
• Need update of 2020 LCS / Proposal Document
• Get people to make lists?
• Next revision
  • Rob Space Ship
  • Patrick - New document format

  • Pablo - coding examples
  • VITAL?
  • Peter Flake - DPI
  • Jim - DPI, Integers, Space Ship
  • Patrick - configuration of architecture of direct entity instances -
  • Default component - predefined attribute that creates a component for an entity.
    • Could a great alternative to fixing configuring direct entity instances
  • Patrick - copying constraints from on record to another input'range - with arrays
    • records and arrays - copying constraints from a record
  • Pablo: Wait on slv(i) ; -- y <= slv(i) ; ... wait on y ;
    • what is the equivalent
    • slv(i) - even if i changes externally, it does not change wrt the wait
    • slv(i) - limit i to process local
    • slv(i) - if a change in i results in the value changing, then the wait on wakes up
    • slv(i) - if slv of the initial i changes or i changes then wake up - wait on i, slv(i)*1 nn because it can be composed. * k := i ; v_prev_value := slv(k); wait on slv until slv(k) /= v_prev_value ; wait on i, slv until slv(k) /= v_prev_value or i'event;
  • Derived everything
    • derived integers - new
    • derived enumerations - tagged enumerations
    • derived records - tagged records
    • derived protected types - extend a fifo to a scoreboard.
    • derived entity - see old (1999 ish) OO proposals
  • Abstract packages
    • defines a generic type and defines abstract operations for that type
    • Goal of being able to use numerics from integer, real, numeric_std, fixed_point.
