(Manisha joined)
Erik: Dmitry asked whether Shalom's comment was addressed in this
proposal. Erik did add a sentence specifying where these functions
may be called.
Dmitry: What about different types of constant and non-constant values.
Suggest that these new functions may be used anywhere pure functions
are used.
Erik: Looking for comparable example in LRM. Most functions, the LRM
doesn't say where they can or can't be used.
Dmitry: In 20.5 the text says that "this function may be used in constant
expressions. Think text for this proposal should be the same.
Tom: Suggest . . ., including constant functions
Erik: Will make that change, and will voice vote later in the meeting.
3015: A proposal was uploaded to address the friendly amendments
Tom: Looks good to me.
Tom: Move to approve proposal

Vote results: 10y, 0n, 0a
- New issues
3672: Hierarchical access to named block in assertion action blocks
Ed: It's not specified what the access path to variables declared in
the action block.
Should the hierarchical path include the assertion label?
Should it include the block label?
Dmitry: It should be consistent with immediate assertions
Ed But what is th the access path for immediate assertions?
Dmitry: Think that immediate is equivalent to "if" An "if" statement
doesn't create a block hierarchy, so hierarchy shouldn't include
assertion label.
Ed: Shouldn't assertion label be part of the access path to variable?
Dmitry: Example
cover property (. . . ) begin : cnt_blk logic cnt; cnt = cnt +1; end
does this count
Ed: Don't think so. Locally defined variable is created each time.
Manisha: Assertion action block is a statement. If you create a block,
it seems that it would be a static block.
Ed: What is the access path to variable?
Manisha: When you use %m in $error in an action block, it will print the
path to the action block including the assertion label.
Section 16.3:
"The optional statement label (identifier and colon) creates a named
block around the assertion statement (or any other statement) and the
hierarchical name of the scope can be displayed using the %m format
specification."
