RE: [sv-ac] Porposal assertion action control tasks

Hi Manisha,

Here are my comments:

1) To define the action of $asservacuouson/of for assertions we need
first a clear definition of vacuous success of an assertion.

2) $assertdisabledon/off for assertions. Let's have the following
property:

assert property (disable iff(rst) a) action1 else action2;

Suppose both rst and a are high and $assertdisableoff has been issued.
Will action1 still take place?

3) cover statement. As I wrote in my previous mail, the definition of
cover statement itself needs a refinement. In my proposal the notions of
vacuous and disabled success for cover directives are irrelevant.

4) I definitely think that this is another errata item (if you are
talking about #805)

Thanks,
Dmitry

Hi All,

I am including a proposal for controlling action block execution. Please
send your feedback. Do we need another errata on this issue or this
proposal can be added to the errata on disable iff (which already has
another proposal).

Thanks.
Manisha
