Hi all -
Attached is a draft revision of BIRD147.4 (tentatively updated to 147.5) to
address issues brought up just prior to the vote in the last IBIS Open
Forum:
Executive summary:
BIRD147.5 changes BCI_GetWave_Block_UI to BCI_Message_Interval_UI and the
Type of both it and BCI_Training_UI from UI to Integer. It softens the
linkage between it and the EDA-determined AMI_GetWave block_size while
retaining the intended primary purpose of providing a mechanism for the
model to inform the EDA tool of the optimal messaging interval to allow the
EDA tool to in turn manage the AMI_GetWave block_size to optimize the
required adaptation time.
Regards,
Bob

Agenda
======
1) Opens
2) Roll call
3) Review of ARs:
Walter: email his example and BIRD 158.4 to the ATM list
Mike L: update the "IBIS 6.2 BIRD Candidates" to rev 7 and send it to the
ATM list
Any other AR-s?
4) Call for any IBIS related patent disclosures
5) Approval of minutes
6) BIRD147.4
- discussion
7) Review BIRD187.1 (All)
- discussion
8) BIRD158 (AMI Touchstone file (R) Analog Buffer Models)
- discussion
9) 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
10) New Redriver flow BIRD (Walter, Fangyi)
- discussion
11) Buffer impedance / C_comp improvements (Randy)
- discussion
Tabled topics:
==============
12) How to handle missing min/max data? (Arpad)
- what should be the governing rule for synchronizing
typ/min/max data?
Pending BIRDs, expected to be rejected:
=======================================
125.1 Make IBIS-ISS Available for IBIS Package Modeling
128.2 Allow AMI_parameters_out to pass AMI_parameters_in data on calls to
AMI_GetWave
145.3 Cascading IBIS I/O buffers with [External Circuit]s using the
[Model Call] keyword
163 Instantiating and Connecting [External Circuit] Package Models with
[Circuit Call]
164 Allowing Package Models to be defined in [External Circuit]
Pending BIRDs, expected to be accepted (currently in discussion):
=================================================================
147.4 Back-channel support
181.1 I/V Table Clarifications
184.2 Model_name and Signal_name Restriction for POWER and GND Pins
185.2 Section 3 Reserved Word Guideline Update
186 File Naming Rules
TBD New interconnect BIRD
TBD C_comp modeling with IBIS-ISS
Pending BIRDs awaiting discussion:
==================================
158.3 AMI Touchstone file (R) Analog Buffer Models
161.1 Supporting Incomplete and Buffer-only [Component] Descriptions
165 Parameter Passing Improvements for [External Circuit]s
166 Resolving problems with Redriver Init Flow
Thanks,
Arpad
