All,
I neglected to add keywords [Pu Ref], [Pd Ref], [Power Camp] and [GND
Clamp] keywords to the [Model] section. These are required to identify
which supply signal_names are used by the Model.

Modeling
All,
Suggested Plan for IBIS Packaging and On_Die Interconnect Modeling
Assuming that we want to have a Packaging and On_Die Interconnect Modeling
solution in ~ 6 months, with minimal impact on the IBIS (.ibs) and EBD
(.ebd) parser, I would like to make the following recommendations:
BIRD IBIS-ISS Packaging and On-Die Interconnect Modeling in IBIS (.ibs)
files.
Add the following new Keywords to IBIS in the [Component] section
[IBIS-ISS Packaging Interconnect File] <file name>
[IBIS-ISS On-Die Interconnect File] <file name>
[Die Pad]
This keyword will be followed by a list of <die pad name> <signal name> to
define explicit die pad names
Intrinsic [Die Pad] names will be a list of all unique signal_names in the
[Pin Section]
Add the following keywords to the [Model] section to specify the supply
signal_names for the model
[Pu Ref] <pullup reference signal_name>
[Pd Ref] <pulldown reference signal_name>
[Power Camp] <power clamp reference signal_name>
[GND Clamp] <ground clamp reference signal_name>
Create a separate specification for
[IBIS-ISS Packaging Interconnect File]
[IBIS-ISS On-Die Interconnect File]
BIRD IBIS-ISS Interconnect Modeling in EBD (.ebd) files.
Add the following new Keywords to IBIS in the EBD section
[IBIS-ISS EBD Interconnect File] <file name>
Create a separate specification for
[IBIS-ISS EBD Interconnect File]
This will be essentially the same as [IBIS-ISS Packaging Interconnect
File] with the following exceptions
Definition of Extended Nets, each Extended Net will have (This could go in
EBD file but would be better in parameter tree format
Extended Net Name
List of EBD Pins
List of Reference Designator Map Pins
Package models will only go between EBD Pins and Reference Designator Map
Pins
