---++ Agenda/Discussion:

Review [[https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.pdf][IEEE patent policy]] (please read before meeting)

Approve March 3 meeting minutes: Motion: Jerry 2nd: John

Continue discussion of language change requirements.
---+++ Package of RTL Hardware Primitives / RTL Building Blocks (Mux, Decoders, FF ...)

More expressive and/or concise way of coding flip flops, Multiplexors, decoders, ...

David Bishop
   * Operator Perhaps to involve clock, reset, enable, reset value, clock edge.

A &lt;= B @ 2 ; -- Clock is implicit - default clocks and reset

Jim Lewis
   * Use subprograms see posts around Feb 18th time
   * Enhance subprograms with defaults similar to generics
   * Need a library of parts (mux, ...)

   * Alternately the following assignment does a simple FF, however some vendors may not support it

A &lt;= B when rising_edge(Clk) ;

David Koontz
   * Also likes library of gate like parts - gives much similarity to gate parts

David Bishop
   * How do we drive vendor uptake on items like this?
---+++ OOP/AOP and Interfaces

Jim Lewis
   * Although I did the previous interface proposal, I think a good implementation of interfaces is to incorporate them into a class.
   * Then allow shared variables to be an interface object on entities as elaborated in the OO proposal

David Koontz
   * Already a class like mechanism in entities and components

What is a Class
   * Container + Methods + internal state (private objects), has polymorphism and dynamic dispatch.
   * It may or may not public objects

John Shields - believes that sharing object classes across languages will be difficult and fraught with trouble

Martin Thompson - need generic programming - and nn need OO - for testbenches
   * AI post links to generic programming topics

Need examples of things that need OO - that illustrate perhaps the advantages of OO over generics on protected types.
