Friendly amendments:
- p.9, example: check_outside is missing an arg
[Korchemny, Dmitry] Fixed.
- p.15, 1st bullet point: "In always_ff procedure" ==> "In always_ff procedures"
[Korchemny, Dmitry] Fixed.
C.2.7: Rephrase 1st paragraph: "The always procedure allowed by IEEE Std 1800-2009 in checkers, but always_comb, always_latch, and always_ff were forbidden. The limitations imposed on the always procedure in checkers included the limitations imposed on always_ff procedures outside checkers. In this version of the standard always_comb, always_latch, and always_ff have been added for checkers. As a result the general always procedure in checkers would have imposed the same limitations as always_ff does. Therefore the usage of always procedures in checkers is deprecated and does not appear in this version of the standard."
[Korchemny, Dmitry] Done.
Also, a question about 17.3. Since we're adding a new limitation on checkers containing procedural code, is it important for us to include an example with a deferred assertion outside a procedure, and point out how its implicit always_comb prevents its checker from being instantiated by other checkers?
[Korchemny, Dmitry] My understanding is that deferred assertions are allowed and they become procedural, as concurrent assertions do. I need to add a clarification. Let's discuss it at today's meeting.
