> 94  - Mantis 2655: Backward compatibility issue with the clocking specification
 
Let me confirm that this issue is about $sampled (I had reported it). The section number should be 16.9.3. Apologies for the confusion.
It's not clear to me why we need to remove the second argument (clocking-expression) of $sampled, that's an optional argument. Section C.2.2 just tells that it's deprecated. Can someone suggest or point me to some doc/mail-thread?
 
 
> 95  - Mantis 2659: Backward compatibility issue with sequence property.
It seems to be a considerable change w.r.t. previous LRM, as the behavior for some of the existing properties would change. 
Can someone please tell me the motivation or point me to the discussion/mail-thread?

Warm regards,

Tapan

	Agenda:
	-------
	 
	- Reminder of IEEE patent policy.
	See: http://standards.ieee.org/board/pat/pat-slideset.ppt
	 
	- Review of ballot issues.
	  The Ballot Comments from the March 2009 P1800 Ballot can be found at:
	 
	  http://www.eda-twiki.org/cgi-bin/view.cgi/P1800/P1800BallotReviewFeedback 
	 
	  The goal is to look over the ballot feedback for SV-AC, 
	  and report back to the P1800 by 4/16 as to how long SV-AC 
	  thinks they require to address the feedback.  
	  The current target  is May 14, 2009.
	 
	 
	Ballot issue discussion and effort estimation:
	 
	82 - Mantis 2646: Assumption in deferred assertion example should be made explicit
	 
	There is no need to make changes in the LRM text since the text explicitly mentions the execution in the Active region.
	 
	Ed moves.
	Erik seconds.
	 
	Motion passed 9y/0a/0n.
	 
	 
	83  - Mantis 2647: Clarification about clock glitches in concurrent assertions
	 
	Ed: Add a clarification that the tool is not required to check the clock glitches.
	Effort estimation: 3 days.
	 
	 
	84  - Mantis 2656: Clarify difference of $global_clock handling in simulation and formal verification
	 
	Ed: Provide an example with multiple clocks
	Effort estimation: 2 weeks
	 
	 
	85  - Mantis 2657: Clarify notion of sequence
	 
	Ed: The word "specifies" is appropriate in the 2nd sentence and it is equivalent to saying "denotes". The last sentence then refers to the dynamic behavior of SV sequences in terms of the denoted set of linear sequences, namely, when an SV sequence has a match (on a trace containing a finite interval of clock ticks).
	 
	Doron: Leave the text unchanged.
	John seconds.
	 
	Motion passed 9y/0a/0n.
	 
	 
	86  - Mantis 2648: Need an example of cyclic dependencies between sequences
	 
	As Shalom mentioned there already is an example of cyclic dependence between sequences on page 319.
	 
	John: It is easy to change the example to pass one sequence as an argument to the other.
	Dmitry: But the intent will be less clear.
	John: Leave the text unchanged.
	Ed seconds.
	 
	Motion passed 9y/0a/0n.
	 
	 
	87  - Mantis 2649: sequence_actual_arg is used to represent the default argument
	 
	Ed: There is no added value in introducing a new non-terminal identical to sequence_actual_arg.
	John: The current BNF is consistent with that one for functions and tasks.
	John: Leave the text unchanged.
	Doron seconds
	 
	Motion passed 9y/0a/0n.
	 
	 
	88  - Mantis 2658: Default values for untyped formals
	 
	Ed: The LRM does not disallow it.
	 
	Effort estimation: 3 days.
	 
	 
	89  - Mantis 2612: `true should have a backtick in a sequence example
	 
	Trivial editorial issue.
	 
	Effort estimation: ½ day.
	 
	 
	90  - Mantis 2650: Ambiguity in a sequence repetition [*0] definition
	 
	John, Ed, Dmitry: The text is correct. Probably some minor clarification is needed.
	 
	We didn't have time to elaborate a resolution, the discussion is postponed to the next meeting.
	 
	 
	91  - Mantis 2652: Future value functions need clarification
	 
	Discussion postponed to the next meeting.
	 
	 
	92  - Mantis 2653: Sequence match not shown in timing diagram
	 
	Discussion postponed to the next meeting.
	 
	 
	93  - Mantis 2654: Error in an example of throughout operator
	 
	Discussion postponed to the next meeting.
	 
	 
	94  - Mantis 2655: Backward compatibility issue with the clocking specification
	 
	Dmitry: The intent is not clear, there is no backward compatibility issue in the specified subclause (16.10 Local variables).
	Tapan: The system function $sampled is intended.
	Dmitry: The deprecation message appears in C.2.2.
	Doron: Leave the text unchanged.
	John seconds.
	 
	Motion passed 9y/0a/0n.
	 
	 
	95  - Mantis 2659: Backward compatibility issue with sequence property.
	 
	Doron: Add a note about the lack of backward compatibility.
	 
	Effort estimation: 1 day.
	 
	 
	96  - Mantis 2660: Add indices to expressions
	 
	Discussion postponed to the next meeting.
	 
	 
	97  - Mantis 2478: Clock flow subclause is not consistent with multiclocked property definition
	 
	Effort estimation: ½ day.
	 
	 
	98  - Mantis 2661: "Syntax 16-19" is in blue.
	 
	Discussion postponed to the next meeting.
	 
	 
	99  - Mantis 2541: syntax errors - missing parenthesis
	 
	Effort estimation: ½ day.
	 
	 
	100 - Mantis 2516: Another contradiction of existing text with 2398 needs to be fixed
	 
	Effort estimation: ½ day.
	 
	 
	139 - Mantis 2496: non_port_program_item should contain assertion_item
	 
	Effort estimation: ½ day.
	 
	- Opens.
	 
	Next meeting will take place 2009-04-16 16:00 UTC (09:00 PDT)
