Check with your simulation vendor. The proper IBIS handling of package models
states that the simulator will use the highest detailed model if present. So
if you have an IBIS s parameter model that should be used and the lower order
RLC will be ignored.

Hi Pratap,
You can Simply edit the IBIS file under the [package] Keyword , there will
be 3 things defined
1. R_pkg
2. L_pkg
3. C_pkg
Just make all the 3 values as "0" in all the Corners Typ/Min/Max.
I Assume you have a O/p IBIS model followed with a Package S Parameters
Connected.
Hope this helps.
Cheers,
Shiva

Hi All,
When we use IBIS output buffer model along with a say HFSS extracted
package model (typically a touchstone format s parameter file) how can we
make sure the IBIS RLC package parasitic numbers are disabled and only the
s parameter package model file is used ? (In tools like ADS)
(Because we anyway have a accurate package model extracted and so we don't
want to have duplicated package models, one in ibis RLC package parasitics
, the othe as s parameter package model)
Thanks
Pratap
