====================================================================== IBIS INTERCONNECT TASK GROUP http://www.eda.org/ibis/interconnect_wip/ Mailing list: ibis-interconnect@freelists.org Archives at http://www.freelists.org/archive/ibis-interconn/ ====================================================================== Attendees from June 3 Meeting ANSYS Curtis Clark* Cadence Design Systems Bradley Brim Cisco David Siadat Intel Corp.

Michael Mirmak noted, as part of Opens, that he understood the earlier GND discussions would be moved to the IBIS-ATM meetings. Radek Biernacki added that A_gnd would be part of the available nodes in the interconnect proposal under discussion in the Interconnect Task Group. Bob Ross noted that the A_gnd node was not going to be recommended, but would not be prohibited. Michael replied that an explicit treatment of A_gnd should be included in Draft 20. Arpad suggested dealing with GND and referencing more broadly after discussions on the Interconnect proposal are closed. The team reviewed the existing Draft 19; some of the background material of the BIRD may be moved into the main body of the document. Much of the team discussion will be embedded as comments in the next released Draft. Radek asked whether Circuit Call is allowed to describe packages. Arpad replied not, that only on-die interconnect is part of Circuit Call. Bob added that one can theoretically zero out the package model and put the relevant information in the Circuit Call block. The team agreed that [Define Package Model] is permitted to co-exist with this proposal, but cannot overlap descriptions of Pins, Die Pads, or Terminals; [Pin Mapping] relationships are less clear, but should not overlap the same Pins, etc. either. Arpad asked whether [External Circuit] can coexist in the same way. Michael suggested this was true, so long as [Node Declarations] does not have to be complete. Arpad agreed, noting that completeness only constrains [Pin Mapping]. The team discussed whether “param” as a term was appropriate, or whether a new term should be adopted. Bob stated that, if the syntax is different, the name should be different, as a preference. The next meeting will continue in-document editing.
