Walter,
Your list is going to take a lot more than ~6 months
to accomplish. I can see a lot of complications around
the [IBIS-ISS On-Die Interconnect File] and [Die Pad]
keywords alone.
If we are looking for "instant gratification" I would
suggest to approve BIRD 116-118 + 125 + 129 + 145 (and 152)
and then work on the more extensive overhaul of IBIS after
that. The BIRDs listed above are pretty much ready to go,
and don't require major changes in the specification and
the EDA tools. I can see this being done well within
6 months and it would go a long way in improving the
package and on-die interconnect modeling in IBIS.
Thanks,
Arpad

Subject: [ibis-interconn] Suggested Plan for IBIS Packaging and On_Die
Interconnect 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]
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
