Hi all,

I uploaded a new version of the proposal: http://www.eda-stds.org/mantis/file_download.php?file_id=5279&type=bug.

It contains the following changes:

· It is clarified that checker standalone deferred assertions become procedural deferred assertions in a procedural checker instantiation (16.4.3 and 17.3.1. See also checker c1 example there).

· It is clarified that event control variables are not sampled in an always_ff in 17.5, and the example has been updated accordingly.

· In F.3.4.6 always replaced with always_ff.

· p.9, example: check_outside added a missing an argument

· p.15, 1st bullet point: "In always_ff procedure" --> "In always_ff procedures"

· C.2.7. 1st paragraph rephrased: "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."

· In the example in 17.3 a missing end added in the module. The module code properly indented.

· Fixed a typo in the example in 17.5.

· In 17.3 Checker instantiation the entire paragraph is included in the change to improve readability.

· Changed "For instance check_outside" to for checker instance check_outside (17.3)

Thanks,
Dmitry
