Minutes of ISAC meeting held via telecom on 23 November 2004. Present: Peter Ashenden, Jim Lewis, Larry Soule, Chuck Swart Absent: Deepak Pant, Ajay Varikat Next Meeting: Thursday 09 December 2004 7pm Pacific Time. Note: Please let me (Chuck) know if this day is OK. TOPIC: IR2047 Backslash in extended identifiers Peter's analysis is accepted. ISAC-Approved ACTION: Chuck to forward to VASG chair. TOPIC: IR2000 Where may/must deferred constant declaration appear Ajay's suggestion to add the word "anywhere" to the suggested wording was accepted. ISAC-Approved. ACTION: Chuck to forward to VASG chair. TOPIC: IR2008 Source value of undriven, non-sourced INOUT, OUT or BUFFER port It was agreed that appropriate comments should be added to both sections 4.3.2 and 12.6.2. ACTION: Peter to update (done) Chuck: submit for electronic vote. ALL: Vote electronically on this issue. TOPIC: IR2040 Problems with OTHERS in aggregates Ajay's analysis was discussed. An outside reviewer commented that and aggregate doesn't have an "index subtype" but, instead, and "index range." This misnaming occurs in many places in the LRM, particularly in section 7.3.2.2. Other sections which should be examined include 3.2.1 array types 3.2.1.1 index constraints ACTION: Chuck to update IR to reflect this. Chuck to consult with Ajay on this. TOPIC: IR2004 Definition of SLA doesn't make sense The example which was submitted will be clearer if 1 sla 1 == 3 is replaced by bit vector equivalents. There was discussion about how other representations were overloading SLA. The general consensus (Chuck believes) is that the current LRM wording is as good as any, so backward compatibility issues dictate that no changes be made. ACTION: Chuck to update IR and to submit for electronic vote. ALL: vote on this IR. TOPIC: IR2009 New std package, containing compiler and target identification information This topic need to be addressed by the VHDL200x environment group. ACTION: Chuck to forward to VASG chair. TOPIC: IR2010 The description of type/subtype relationship could be better Peter's analysis was accepted. ACTION: Chuck to submit for electronic vote. ALL: Vote on this IR. TOPIC: IR2011 A package body should be able to consist of several files The submitter's issue is unclear, but the request itself should be forwarded to the Modeling and Productivity group. ACTION: Chuck to submit for electronic vote. ALL: Vote on this IR. TOPIC: IR2012 VHDL lacks inherent statements to describe the most basic hardware design equations This request should be forwarded to the Modeling and Productivity group. ACTION: Chuck to submit for electronic vote. ALL: Vote on this IR. TOPIC: IR2013 Exact subtype "matching" for port associations This IR touches on a very difficult issue--that of signals as subprogram parameters. Chuck will collect information relevant to this topic. ACTION: Chuck to gather "pre-analysis" information. TOPIC: IR2014 Allowance of the keyword "all" in place of a sensitivity list is desirable This is FT-19. ACTION: Chuck to submit for electronic vote. ALL: Vote on this IR.
