RE: [IBIS-Users] Regarding S-Parameters models included on IBIS

Hi Esdras,

 

It is possible to include an S-Parameter definition of a package model in an
IBIS file using the [External Circuit] keyword. The [Model] constructs for
the buffers remain separate in the IBIS file. However, your real challenge
will be to put that to use in a Signal Integrity software application. Very
few of them support an IBIS file that uses the [External Circuit] or
[External Model] constructs.

 

Most high-end silicon vendors provide their S-Parameter package models in
separate Touchstone Files along with the silicon models in either IBIS or
SPICE format and leave it to the end user to put them together in a
simulation in the way that suits their methodology and tools.

 

Thanks!

Tony

Hi ibis experts!

 

Is it possible to include s-parameter definition for a package into an IBIS
model, or it is necessary to have the lumped RLC equivalent?

So far we have only available the s-parameters model for the package, but we
don't know how to include this info into the IBIS model...

We will really appreciate your feedback regarding this point. Thanks in
advance!!!

 

Best Regards: Esdras
