The minutes were approved without objection Michael provided an update on his two ARs. He is awaiting more information from Pete Pupalaikis on S-parameter compression. Sam Chitwood is looking for referencing information, but will only examine the public IBIS summit materials, as he no longer has access to his previous work presentations. Arpad Muranyi noted during Opens that there have been no changes to the port-mapping or pole-residue drafts since the last meeting. He is now looking for feedback on the existing documents. The next step is to write up the TSIRDs for each, but he would prefer not to get into details of the TSIRDs if the team prefers a different direction for either document. Michael took the AR to contact Steven Parker regarding ensuring that the latest drafts are available on the Interconnect web site. The team continued reviewing Draft 2 of the Touchstone 2.1 document. Some discussion was held regarding how the example headers should be presented, and whether all the examples need to be complete. Arpad noted that the R character and resistance values are always at the end of the option line in all examples. An example is present in the 2.1 draft that shows resistance in the middle of the option line. Several additional comments in the document from Arpad and Randy were resolved. Michael noted that the phrase "less than allowed" appears under the noise data section, for x5. The meaning of this is unclear and this section may need rewriting. Arpad took the AR to check with his colleagues on the meaning of x5's "less than allowed" noise parameters phrase. All but one or two comments in the draft were resolved. The next meeting will focus on the remaining questions and comments in the draft, with the objective of pushing the document to the Open Forum for a vote as soon as possible. Arpad moved to adjourn; Randy seconded the motion. The meeting adjourned. The next meeting will be held October 18, 2023. ================================================================================ Bin List: 1) [Complete draft Touchstone document separating version 1.0 and 2.0 into their own chapters] - REMOVED 2) Create structures to encapsulate Touchstone 1.0 data in Touchstone 2+ specifications - TABLED 3) Complete draft Touchstone 2.0 document containing TSIRD3 and TSIRD4 draft (Muranyi) – COMPLETED IN DRAFT 10 4) Complete pole-residue format BIRD draft (Muranyi) 5) Complete port naming proposal (Katz) 6) Create alternatives to the Touchstone 1.0 option line before the "R" character - TABLED 7) Complete ISS-IRD 1 Draft - Enable Cascading of S-parameters Through W-element (Mirmak) - TABLED 8) Complete/revise Touchstone 3.0 draft outline (Mirmak) – dependent on several items above Tabled ARs: - Arpad to give an example of the physical connectivity needed for EMD automation.
