Agenda
======
1) Opens
2) Roll call
3) Review of ARs:
Arpad: Submit the Alphanumeric Pins BIRD draft to the Open Forum
- done
Arpad: Submit the Clocked Rx AMI Models BIRD draft to the Open Forum
- done
Michael: Send out his presentation to the ATM reflector
- done
Fangyi: Review Walter's draft of BIRD211.4
- ???
Any other AR-s?
4) Call for any IBIS related patent disclosures
5) Approval of minutes
6) BIRD211.4 draft1 IBIS AMI Reference Flow Improvements (Walter)
- update / discussion
7) BIRD213.1 draft10 (PAMn) (Walter)
- update / discussion
8) Updates on any of the following topics:
- Power Supply Induced Jitter (PSIJ) study (Randy)
- GDDR6x signaling with IBIS-AMI (Walter)
- Supporting PI modeling/simulation in IBIS (Zhiping)
9) List of potential new topics mentioned in previous meetings:
- AMI file root name checking
- Update outstanding BIRDs with new IBIS v7.1 page numbers
10) Motion to adjourn?
Topic bin list:
===============
- Removing the single-ended input threshold requirements for
differential buffers (Mike M.?)
- Removing the single-ended characterization load requirements for
differential buffers (Mike M.?)
- Guidance for power-aware vs. AMI models – do we have rules for
how a power-aware (and therefore potentially non-LTI) buffer
analog data set should be used with IBIS-AMI algorithmic data?
(important topic - 2018 ASIA IBIS Summit presentations)
(the spec. may not need to be changed for this)
- Digital signing of DLL/SO files. Should it be mentioned in the
spec, or required?
Tabled ARs:
===========
Tabled topics:
==============
11) Jitter HF/LF components and Jitter Amplification (Mike M.)
12) Other DDR5 related topics
- rise fall asymmetry
13) New BIRDs from Editorial Task Group? (Bob/Radek)
a) Specify buffer reference terminals for pins ([Pin Reference])
b) Simulation (aka DIA) vs. DUT (depends on #a)
c) C_comp and package reference in simulation clarifications
(depends on #a)
d) Make changes to the [Receiver Threshold], once a) and b) are
resolved
e) Fix all the referencing problems in the current specification
(after Randy’s C_comp proposal and BIRD189 are done)
(BIRD181.1 Bob, Mike L.)
14) How to handle missing min/max data? (Arpad)
- what should be the governing rule for synchronizing
typ/min/max data?
Pending BIRDs awaiting discussion:
==================================
166.4 Resolving problems with Redriver Init Flow
190 Clarification for Redriver Flow
Thanks,
Arpad
