RE: [sv-ec] Ballot issue #106

Hi Dave,
 
Regarding the first point: Do you mean that "will not track" implies
that input arguments cannot be used
in coverpoint expressions as coverpoints track values? Please clarify.
 
Regds,
Swapnajit

	Well, again, I think the instructions from P1800 are to work on
ballot issues only.  Neil can confirm.
	
	I don't think the first point is very unclear.  Look for the
phrase "will not track" in the paragraph about covergroup arguments.
	
	The second case may actually be unclear (I started off writing
that it wasn't.)  The visibility of the arguments should follow the same
rules as resolving arguments in any other scope.  However, the
coverpoint is a sub-scope of the covergroup scope, so the bin name
should arguably hide (or override) the name in the higher scope.  On the
other hand, bin names really aren't visible in the language, except in
cross select expressions, so maybe they don't.  Yes, this should
probably be clarified, but it is not a ballot issue against 1800-2009.

		Hi Dave,
		 
		Did you get a chance to look at the two points that I
raised alongwith #106? These were not part of the
		ballot, but were posted to the reflector as comments. I
am mentioning them once again for your reference. 
		 
		- Use of "input" type arguments as part of coverpoint
expressions. I do not see an
		  issue with this but just wanted to clarify as LRM is
silent on this. LRM just shows
		  "ref" arguments being used as coverpoint expressions.
		- Use of covergroup arguments as bin name. Probably we
should mention in LRM
		  that this should be an error. An example of this is
given below:
		  covergroup cg (int f1,..)@..
		     coverpoint a {
		        bins f1 = {..};  // Note "f1" is used as bin
name
		     }
		  endgroup
		 
		Regds,
		Swapnajit
