While this is true, one ***CAN*** make a separate package IBIS model
in a standalone .pkg file, which does not require all the IV and Vt
curves, or any of the buffer related parameters.

Kee Chai,
To create and IBIS model file you need all the relevent V/I and V/T data
points, a valid pinlist file, master Pin file, RLC file. Also make sure that
you have the timin-process loads (Vmeas, Vref, Rref and Cref) for all I/O,
Output, 3-state buffers.
In order to create the pin-list section of the ibis file, you will need to
extract the [Pim], signal_name, model_name, R_pin, L_pin and C_pin from the
master-pin, pin-list and RLC files. This you can do using MS-Excel,
Star-Office or you if you are prficient in a scripting langauge you can
create script to do this.
I hope this helps

Hi guys,
I have a question on IBIS package model:
If I have a file containing RLC which is extracted from a package using some
extraction tools such as Ansoft, can I represent it in IBIS model?
When I look at the IBIS file, it always contain other sections on capturing
timing information such as V/I curve for rising and falling waveforms. It
only captures package modeling in one of the sections in IBIS modle file.
In my case, Can I create a IBIS model file only contains package information
and no timing information?
Thank you very much.
Best Regards
kee chai
