Walter, and Everyone,
I made another version of your IBIS file in which I
implemented the same package and on-die interconnect
using the concepts in BIRDs I wrote (see attachment).
I will explain all the details in the ATM teleconference
today, but I would like to encourage everyone to take a
look before the meeting if possible to be familiar with
the content.
Mike L.,
Could you please post the attachment to the ATM reflector?
Give it the following title: "Package modeling syntax
comparison, example 1". For the author you could put both
of our names there.
Also, I consider this to fulfill the AR I had to write a
complete example to illustrate my proposals.
Thanks,
Arpad

Subject: [ibis-macro] Tuesday Presentation
All,
At MM's request I have introduced the first test case to be implemented with my
proposed package and on-die methodology and for Arpad to implement with BIRDs
116, 125, ...
The test case contains 3 Tx and 3 Rx differential channels. There is an on-die
s4p between the pads of the die and the ibis models of the Rx and Tx.
There is a differential subckt and a coupled differential subckt that are
parameterized by a Length which is different on each of the six differential
pair channels.
This is real data from a 2000 pin BGA component currently in production. The
hundreds of differential channels are reduced to six, and all of the other
interfaces have been removed to simplify the comparison of my proposal and
BIRDs 116, 125, ...
The test case is enclosed as a legacy IBIS file with comments indicating the
on-die and package models that need to be applied.
On Tuesday I will show implementations of these models in legacy IBIS format,
using legacy IBIS files with parameter tree sections, splitting the IBIS file
into an EMD file (parameter tree format) and a bare-die legacy file, and
finally converting the bare-die legacy file into an ibisx file.
