Call for patent disclosure:

Review of ARs:
- Walter update BIRD 123.2.4 and send to Mike for posting
- Sent, not yet posted
-------------
New Discussion:
BIRD 127.2:
- Radek's comments were reviewed/discussed/debated.
- Output params. In ModelSpecific section?
- Motioned, seconded, and approved to table this, until Radek is present to
explain.
Walters 5.1 Resolution Request - Only document 5.1 behavior in 5.1?
- Walter proposed, Yes, as a formal resolution.
- Walter proposed that a separate document be created, explaining the
differences
between 5.0 and 5.1.
- It was pointed out that this will be the first break from backward
compatibility
in IBIS history.
- Walter noted that AMI default is 5.0, thus protecting the unwary.
- It was claimed and defended that certain fundamental flaws in 5.0 force us to
break with backward compatibility.
- Motioned and seconded that we table the discussion until next week, in the
interests
of furthering the Jitter BIRD discussion.
Jitter BIRD (123):
- Greg's latest updated drawing was presented/discussed.
- Walter clarified certain recent comments, regarding Tx jitter insertion point.
- It was noted that the use of the `USE_INIT_OUTPUT parameter was deprecated in
5.1,
thus forcing the AMI_GetWave function to perform both the linear and
non-linear
portions of the equalization, every time it is called. (Was this wise, from a
performance perspective?)
- Jitter spectral density vs. amplitude histograms were debated, at length.
It was noted that both are really required, in order to completely describe
jitter.
- The practical example of how to include power rail fluctuations in BER
modeling was
presented, as an aid in understanding the requirements of jitter
specification mechanisms.
- Motioned, seconded, and approved that the jitter spectral density discussion
be
tabled until we get 123 out the door.
Resolutions Accepted:
- That we wait for Radek before discussing BIRD 127 any further.
- That we resume the 5.1 vs. 5.0 discussion, next week, and that we try and have
something resolved by the next Open Forum.
- That all mention of jitter spectral densities will be tabled for further
discussion,
until after we've completed BIRD 123, and that the RX_EXT_REF parameter will
be
removed from BIRD 123, to be included in the future BIRD covering jitter
spectral density.
