Opens:

Michael asked about the topic of the redriver flows.  He plans to invite an 
expert from his side to the meeting next week to discuss redrivers and the 
simulation flow.  Michael moved to untable the redriver discussion topic.  
Arpad asked which specific agenda item this is related to.  Michael thought 
item 13 for BIRD166.4 would be the best starting point, but he was not sure 
the status of the other BIRDs.  Michael amended his motion to untable agenda 
items 13, 14, and 15.  Curtis seconded.  There were no objections.

New Discussion:

Supporting PI modeling/simulations in IBIS:
Zhiping had a meeting with the MST professor regarding the IBIS Summit 
presentation on improving IBIS modeling of PSIJ.  Zhiping suggested for MST to 
do additional research and present the results from that study in this forum 
for feedback.  He commented that PSIJ can be an important effect to model.  
Arpad suggested to also collaborate with Michael on his timing BIRD.  Zhiping 
agreed this would be a good to discuss.

GDDR6x Signaling:
Michael asked if this has been discussed in JEDEC.  Justin will find out if 
single-ended PAM4 has been discussed in JEDEC.
