["John Horner" <horner@xxxxxxxxxxx>]

Sudheer,

When you say you have a package model, I assume that means you have =
assigned one in the IBISDevice editor. If this is the case, then any of =
the other pin parasitics defined in the estimated or at the pin level =
are ignored since the package model takes precedence. Be sure to update =
the package model (defined as a packagemodel in the DML browser) and =
then update the board with the changed model. If you edit the model =
using the Library Browser you should see a confirmer stating that the =
model has changed and do you want to update the board with this new =
information. I'll send you a small testcase showing that the changes are =
indeed reflected in the simulations in a private email.

Regards,

HI
I have a doubt regarding package model  assignment=20
associated with  multi board analysis=20

I have attached  package model for both the connectors, connecting =
between boards with no buffer models assigned to them . I am not able to =
differentiate  variation in the results with package models (eventhough =
I have changed the C_pkg to higher valus). I afraid the package =
parasitics  is not included in my analysis=20

Does anyone has worked on these kind of simulation ?=20



Thank you=20
