Gord Vreugdenhil will join. - D4 Review . JH will work with the D4 reviewers to create the response to the editor. To make these official, we will voice vote the response to the editor. - Extension period plan (due 2007-11-12) . 2007-10-30 due date for items and effort plans. - Voice vote on friendly amendments . 1549 (missing word "results" in "results in illegal syntax"). Ballots closing 2007-10-30: - 1567: In Syntax 22-7 there should be no semicolon [JH]. - 1682: Future value functions [DK]. Negative vote. Ballots closing 2007-11-05: - 1648: Default disable [DK, EC]. - 1731: Sampled value functions with arbitrary clocks [DK]. - 1757: accept_on, reject_on [EC, DB]. - 1737: Incomplete fix from 1381 Feedback State: - 1641: Severity for general error messages [MK] . Friendly amendments and feedback from Shalom addressed? . E-mail ballot or voice vote? - 1601: New keyword for untyped formal arguments [LP] . 1549 has passed, so this needs to be revised and aligned. - 1729: Immediate assume, cover [EC] . AI: MK will send mail about what of 1729 needs to be aligned with 1641. Major items: - 1932: LTL Operator [DK, DB] - 1900: Checkers [DK] General working items: - 1756: Control of assertions in initial blocks [EC] . DK: Let's try to write sketches of two possible solutions. One can be adding an argument to the assertion control, another to add another control task. DK will write an e-mail with the sketches. Then we will get feedback. - 2005: Glitches with immediate assertions [ES] - 1995: Assertions and checkers in for loops [ES] - Other items Notes: ------- - Reminder of IEEE patent policy. - D4 Review . JH will work with the D4 reviewers to create the response to the editor. To make these official, we will voice vote the response to the editor. JH will finish a.sap and send for review. We will voice vote in the next meeting. - Extension period plan (due 2007-11-12) . 2007-10-30 due date for items and effort plans. JH has collected the effort estimates so far, but he did not make his own. . People will review the mantis items to see what else we may want to work on in the extension period. We will take one more week to get effort estimates for such items. . DK will keep the growing list of items to be worked on in the extension and send it out periodically so that people can confirm that their items are on the list. - Voice vote on friendly amendments . 1549 (missing word "results" in "results in illegal syntax"). . Voice vote to approve: 9y/0n/0a. - 1728: Let [DK]. . Have the friendly amendments been addressed? Has the proposal been aligned to D4? Do we need to have another e-mail ballot? . Voice vote to approve: 8y/0n/1a [Erik Seligman abstained]. Ballots closing 2007-10-30: - 1567: In Syntax 22-7 there should be no semicolon [JH]. - 1682: Future value functions [DK]. Negative votes. . Feedback from DB has already been addressed. . Discussion of feedback from MK. DB argued that we don't have a definition of when attempts end, regardless of the future value functions. We talked about not saying anything about when these attempts end or when the action blocks execute. MK will send a suggestion about rewording. - Discussion of name resolution questions involving "bind". Gord Vreugdenhil will join. . GV: Context of bind statement and context of target are important. . GV: Names in the bind statement are to be resolved in the context of the bind target. Exactly what are the assumptions about this statement? References to types are problematic. . GV: A bind should not impact name resolution decisions that have already been made in the target. . GV: Names that can be referenced in bind must be valid hierarchical references in target. . GV: How do we deal with a type reference in bind? Type and package references in a bind statement resolve in the context of the bind statement. . JH: We need to be able to get a bound instance to pick up a type parameter override from a target instance. How do we specify that? . GV: If you want to use something as a type from the target, you would need to use type(yadda). Ballots closing 2007-11-05: - 1648: Default disable [DK, EC]. - 1731: Sampled value functions with arbitrary clocks [DK]. - 1757: accept_on, reject_on [EC, DB]. - 1737: Incomplete fix from 1381 Feedback State: - 1641: Severity for general error messages [MK] . Friendly amendments and feedback from Shalom addressed? . E-mail ballot or voice vote? . Manisha has revised according to Shalom's comments. . Voice vote to approve: 7y/0n/2a [Johan Martensson, Erik Seligman abstained]. - 1601: New keyword for untyped formal arguments [LP] . 1549 has passed, so this needs to be revised and aligned. . JH will call for an e-mail vote. - 1729: Immediate assume, cover [EC] . AI: MK will send mail about what of 1729 needs to be aligned with 1641; then EC will revise; then JH will call for e-mail vote. Major items: - 1932: LTL Operator [DK, DB] . DB: There has been progress on the vacuity definition. JM's definition may be better than the existing one, but it does not seem to solve the problem with the until operator. . DB: Question about clocking for eventually, e.g. @(clk1) a |-> eventually @(clk2) b JH: In this case eventually should be clocked at clk1. . X[0] as alignment to inherited clock. DB mentioned Dana Fisman's presentation that involved this topic. . Issues about multiclocks and LTL operators. 1683 is not being pushed yet. DB will need to include restrictions on clock changes with LTL operators for now. . JM: We should not delay 1932 based on coverage ideas. . DB will say that vacuity for LTL until is not defined. - 1900: Checkers [DK] . DK did not receive feedback on the checkers proposal. . Missing formal semantics for free variables. No feedback on the rest. . We don't have convergence on the non-deterministic free variables. . DK: Universal quantification is important, but not the only usage. Additional syntax should be used for different usages. General working items: - 1756: Control of assertions in initial blocks [EC] . DK: Let's try to write sketches of two possible solutions. One can be adding an argument to the assertion control, another to add another control task. DK will write an e-mail with the sketches. Then we will get feedback. . DK: Most people preferred the first option. MK has not sent feedback yet. . EC: How will you run these in formal? We did not get to these items: - 2005: Glitches with immediate assertions [ES] - 1995: Assertions and checkers in for loops [ES] Next meeting: ------------- 2007-11-06 at 17:00 UTC (10:00 CST), 2 hour slot.Received on Tue Oct 30 12:02:28 2007
