Subject: [IBIS-Users] SSO IBIS Modeling question

Hi IBIS experts.
This questions, is regarding to SSO simulation on a package.
If I want to model the following:
|------(RLC1)----------(RLC1)-----------(RLC1) --|
| | | |
| (drv) (drv) |
(RLC) (RLC) (RLC) (RLC)
| | | |
(PWRBALL) (SIG-BALL) (SIG-BALL) (PWR-BALL)
(A1) (A2) (A3) (A4)
With a package model it seems pretty straight-forward to model all the
(RLC), now
It is not obvious to me how to model the (RLC1) ??????.
This is for the Package.(RLC) modeling
A1 Len=4.69838 L=0.284n C=0.1775p R=0.05 / Len=0 C=0.8p / | PWR-BALL
A2 Len=4.69838 L=0.284n C=0.1775p R=0.05 / Len=0 C=0.8p / | SIGNAL
A3 Len=4.69838 L=0.284n C=0.1775p R=0.05 / Len=0 C=0.8p / | SIGNAL
A4 Len=4.69838 L=0.284n C=0.1775p R=0.05 / Len=0 C=0.8p / | PWR-BALL
This is for the Ring (The Driver of A2, is connected to RING and to VSS
-----------------------------------------------------------------------
(Ground Balls, not shown in the above diagram)
B1 VSS NC
B2 VSS NC
------------------------------------------------------------------------
(Power Balls)
A1 NC RING
A4 NC RING
-------------------------------------------------------------------------
(Signals drivers)
A2 VSS RING
A3 VSS RING
-------------------------------------------------------------------------
Anyway, it seems to me that I can do this creating an EBD model, but
I was wondering, if there is some way to represent this with the
[Package Model] directly?.
Thanks.
