AR: Kim Heliwell ask Bob Haller for November meeting notes. No report. AR: Mike update priority list with Kim's input. Done. See discussion below. - Discussion of parser bug priority list We have already filed a bug for the 1st item on the new priority list, "[Model] Vinl and Vinh enclose Vmeas". Bob Ross noted that the IBIS Open Forum has 8 parser bugs in the queue now. The new list appears to have a more reasonable spread of score numbers because a bug in the scoring script was fixed. We turned our attention to the 2nd item on the list: 2.2 Latest [IBIS Ver] used IC vendors may be reluctant on this one because in practice, old IBIS files are simply never updated. Instead of asking IBIS files to "say they are new", maybe it would be better to propose that ibischk would simply apply new checks to older files, as long as each check was a commonly understood requirement at the time the older IBIS version was released. Non-monotonic combined curves are an example. There are reasons why both combined and single table checks are useful. It was originally thought that tables could be considered individually. Bob Ross stated that when ibischk4 reports non-monotonicity for a table, it can be necessary to run again with [IBIS Ver] reduced, to identify which curve is the biggest culprit. Mike suggested an ibischk command line option to override the file's [IBIS Ver]? It was felt that too many command line options are usually a bad thing. We noted that even small amounts of non-monotonicity are acceptable to most simulators, yet ibischk flags any amount on non-monotonicity. To complicate matters, a new bug proposal from Randy Wolfe would require that [submodel] be considered for combined V/I. AR: Mike write up straw man bug report and discussion for check 2.2 AR: Bob Ross contact Kim - Opens for new items The next meeting would be too close to the upcoming IBIS summit as scheduled, so it is moved to 14 feb 2006. Next meeting: 14 Feb 2006 11-12 AM EST (8-9 AM PST) Phone: 1.877.384.0543 or 1.800.743.7560 Meeting access: Meeting ID: 90437837 Meeting ended at 12:10 PM Eastern Time.
