Call for IBIS related patent disclosures: - None Call for opens: - None Review of previous meeting minutes: Minutes from the July 21 meeting were reviewed. Randy Wolff moved to approve. Bob Ross seconded. Without objection the minutes were approved. ARs: - Bob Ross to review the BIRD181.2 draft - Bob made a correction. - Bob Ross to verify fixes for ibischk bugs in ibischk702 test executables - Done - Mike LaBonte to test new ibischk702 test executables against IBIS file library - Done IBIS Quality Specification: Mike LaBonte reported that feedback had been received from Jason Chung of Global Foundries. Jason wrote that on page 23, Open-sink should be paired with Open-drain, not Open-source. Mike asked if that really was an error. The sentence before the offending sentence was about Open-drain. He was not sure the Vref vs. Vmeas statements were valid. Bob Ross said the relationship between Vref and Vmeas was not a requirement. Randy Wolff said the Vref/Vmeas statements were valid. He noted that open-sink/drain had a Pulldown and no Pullup, verifying that the logic of those sentences was correct. Mike suggested moving "and Open-sink" to the first sentence. Jason had given permission to be cited if a QuaIL entry was to be written. It would be QUAIL3. Mike will draft a new QuaIL and ask Jason to approve it. Bob noted an update to the IBIS Quality specification might be a 2.1 version. AR: Mike BIRD181.2: Bob Ross showed proposed changes for the BIRD181.2 draft. He felt in general that the notation describing voltages was very cumbersome. Bob had made changes to Table 1 in Notes on Data Derivation. Mike said each item inside V(a,b) had to be a node name. Bob noted that "0" was a node name in SPICE. Mike asked to see the table in the latest draft of BIRD181.2 from ATM meetings. Bob found and showed draft 2 of BIRD181.2. Mike felt the table should be consistent in use of the ideal ground reference node name, and also that ECL entries like "0.0 V" should be like the others, in V(a,b) form. Randy said it should be OK to discuss this in quality meetings, but occasional ATM review was a good idea. AR: Bob Ross to send Table 1 proposal for BIRD181.2 draft to Mike LaBonte AR: Mike LaBonte post proposal from Bob Ross and BIRD181.2_draft2.docx to Quality archive New parser bugs: Bob Ross reported there were no new bug reports. IBISCHK 7.0.2 development: Bob Ross said this was done and had been published. He said it was unfortunate that the next Open Forum meeting was at least a month away, because we usually held a vote to accept the software and release the funds. Mike LaBonte noted that those votes were really to accept the software, the vote to spend the funds had already been passed when the project was approved. Randy Wolff suggested the Quality Task Group should be the one to vote to accept. Bob said an Open Forum vote to accept was written into in the contract. Randy checked and verified that language. He said an email-only vote could be held, closing on Aug 21. We agreed to that approach. AR: Randy Wolff to conduct email Open Forum ballot to accept ibischk7.0.2 software. Mike said he had made a minor correction to the ibischk7 web page. The Linux RedHat executables were compiled with RHEL7, not 6. Tabled topics (no discussion without motion): - IBIS-ISS parser Bob Ross moved to adjourn. Randy Wolff seconded. Without objection the meeting ended. Meeting ended: 11:54 ET Next meeting August 17, 2020
