No email servers errors, it was a problem using stationery to send email, which was introducing too many header lines in the email. Mike will revise bug report - done, posted to the web site. Kim will test the testcase - done, works OK. - Opens for new items - Review of updated parser bug report for IQ 2.2 check Approved as written. File should be sent as an attachment, it will be renamed. AR: Mike send parser bug report to ibis-bug@eda.org - Review of iq_spec_ibischk_review2aug2005.txt It was difficult to find the latest IQ specification on the website. We looked at the ibis-macro website and agreed that it would be good to redesign the ibis-quality website in that mold. AR: Mike clone macromodel web page for IQ CHANGE: In section 1.1 add 5 bullets describing the 5 IQ levels. This lead to a discussion of problems with the current IQ numbering system. The lowest quality level is 0, which sounds like "no quality". We wondered how entrenched our current numbering system is, and if it is possible to change at this point. Kim said that someone on the silist was asking for a level 1 model at one time. We should ask the silist if anyone is using it internally. We do know that Micron is using IQ and would like to change the numbering so that the lowest level is not 0. We could change to a letter grade system to avoid confusion. Using sequential ABCDE we would have to choose whether A is high quality or low quality. It depends on which end of the spectrum needs to be left open for expansion, and if there might be confusion with school grades if A is low quality. Another possibility is to use non-sequential letters that signify a word: I bischk Q uality checklist M easurement S imulation Even better, the letters could cumulatively form a multiple letter quality designation. For example, I means the file has passed only ibischk and IQMS means the file has passed all checks. We may have "piled on" too many checks, making it difficult to achieve the current level 1 designation. As far as we know only SiSoft uses overshoot parameters, for example, and these are not readily available. A further issue with the overshoot parameters is that IBIS can't capture the new DDR2 overshoot specs from JEDEC (V-s integration). We decided to continue discussion of improving the IQ rating system in the next meeting. Also we hope that Moshiul Haque would be present for the discussion, since he previously registered the points discussed. AR: Bob contact Moshiul Haque about the next meeting Next meeting: Apr 11 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 12:09 PM Eastern Time.
