New Discussion:

Standard Power Integrity Model (SPIM) BIRD draft:
Chi-te said she had not received any feedback since Kinger had sent out draft7.
No one in attendance had any new feedback.  Arpad asked everyone to review
draft7 and provide feedback.

Modify C_comp model for T-coil modeling:
Walter reported that this topic had come from a customer engagement.  He said he
was waiting for the customer to verify that it is important.  Walter moved to
table the topic.  Bob seconded the motion.  There were no objections.

AMI Support for [Test Data]/[Test Load]:
Proposal for a new keyword:  [Clock Group]:
Michael reported that he plans to work on BIRDs for these two topics, but it
will not happen soon.  He asked that these topics stay on the agenda and not be
tabled.

Multi-level analog buffer modeling (PAMn, C-phy, etc.):
Arpad summarized previous discussions, which he had started several months ago.
He recalled that there had been differences of opinion as to whether this
enhancement to analog modeling was necessary and how much work it would entail.
He said Randy had suggested that the simplest solution might be to define a
stimulus input scheme that allows for multi-level signaling.  Arpad said he
would eventually like to continue discussion on this topic, but he had no new
updates.

- Curtis: Motion to adjourn.
- Michael: Second.
- Arpad: Thank you all for joining.
