Call for patent disclosure: - No one declared a patent. AR Review: - Moshiul add to 5.2.16 - Done - Mike mark 5.2.17 for deletion - Done - Mike mark IQ 5.3.3 for deletion - Done - Mike unswap "S" & "M" in 5.3.17 - Done - Mike will send link to Arpad's presentation on waveforms for diff pairs - Done - David produce response to JEITA - TBD New items: - Mike said there are enough changes to warrant posting a 1.1y IQ spec - Moshiul sent files showing Micron's IQ-based quality process: - In the first figure in the PDF: Blue lines correspond to JEDEC requirements - Review of new text for 5.2.16 provided by Moshiul: - Bob: excluding D_overshoot* is a more severe check - D_overshoot* provides a relaxation of rules - Kim: SiSoft put a high value on these parameters - Mike: Is there a convention for translating area to shape? - Bob: JEDEC has a triangle picture - David: surprising, that shape gives maximum time span for area - Offered as an alternative to integration during simulation - BIRD 103 allows for: - Separate high and low side overshoot limits - Maximum amplitude - Maximum area - Mike: Can we delete this check entirely? - Bob: SiSoft felt that all IBIS features should be used - Kim: Now the IQ group has semi-conductor representation: - Moshiul: It is too difficult to get D_overshoot* data - David: Agreed - Mike: We could have a "square box" limit check for 5.2.16 - David: Should comment the assumed waveshape if given - Kim motioned to delete 5.2.16 completely - No one seconded the motion - Moshiul: We could address this when BIRD 103 is approved - This would alleviate concerns about D_overshoot* param applicability - Bob: It will be at least a year before the BIRD is in effect - Bob: Concerned about "docking" good models - Maybe "must" is too strong, "should" might be better - Mike motioned to change to: "If D_overshoot_high, D_overshoot_low, and D_overshoot_time subparameters are based on area limit specifications in the datasheet, then the basis for the chosen voltage and time limits must be documented in the file." - David seconded the motion - Bob and Kim agreed - The proposal passed AR: Mike change text of 5.2.16 to require basis documentation AR: Mike post 1.1y version of IQ specification, with latest edits Next meeting: 04 dec 2007 11-12 AM EST (8-9 AM PST) Phone: 1.877.384.0543 or 1.800.743.7560 Passcode: 90437837 Meeting ended at 12:14 PM Eastern Time.
