Agenda
======
1) Opens
2) Roll call
3) Review of ARs:
Any other AR-s?
4) Call for any IBIS related patent disclosures
5) Approval of minutes
6) Standard Power Integrity Model (SPIM) in IBIS (Kinger)
- discussion
7) Possible topics for the upcoming ATM meetings (Zhiping)
- PSIJ
- Dr. Hwang is working with Randy on an updated simulations
- Diode
- I made a draft and would like to check if we are on the right direction
- Inductor
- Hanfeng Wang from Google made a draft and would like to discuss it
8) Updates on any of the following topics:
- AMI Support for [Test Data]/[Test Load] (Michael)
- Power Supply Induced Jitter (PSIJ) study (Randy)
- GDDR6x signaling with IBIS-AMI (Walter)
- Supporting PI modeling/simulation in IBIS (Zhiping)
9) Motion to adjourn?
Topic bin list:
===============
- Removing the single-ended input threshold requirements for
differential buffers (Michael?)
- Removing the single-ended characterization load requirements for
differential buffers (Michael?)
- 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?
- Multi-level analog buffer modeling with I-V and V-t curves
Tabled ARs:
===========
Tabled topics:
==============
10) Jitter HF/LF components and Jitter Amplification (Michael)
11) Other DDR5 related topics
- rise fall asymmetry
12) 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.)
13) How to handle missing min/max data? (Arpad)
- what should be the governing rule for synchronizing
typ/min/max data?
Pending BIRDs awaiting discussion:
==================================
Thanks,
Arpad
