Hi Timmy,
 
I'm taking note of Michael's response in providing this response.
 
Depending on which simulator you are using, you may be able to use the
IBIS v4.1 [External Circuit] keyword to accommodate your W Element
package model. It all depends if the simulator supports that. Another
alternative, again depending on the simulator tool, is to add the W
Element as a 'black-box' separate entity in the overall circuit to be
simulated.
 
Yet another approach I've used before, if your target simulator is a
SPICE engine that supports IBIS models, is to write a SPICE .SUBCKT that
includes both the W Element and the IBIS model.
 
Regards,
Tony

Subject: [IBIS-Users] Package Modeling for W-element


Hi
 
I'm just wondering if there are already keywords available in the IBIS
v4.1 Specification to represent the package modeling for W-element
model. From the IBIS Spec, I notice that there is the [Define Package
Model] keyword; however, there aren't any sub parameters that actually
represent the frequency dependant element. 
 
I would be glad if someone can answer my concern on bringing this
W-element package modeling in the IBIS file by using new keywords. The
current [Define Package Model] only cater for Lumped RLC and Segmented
RLC package modeling at the moment (please correct me if I'm wrong). So
is there any plan that the IBIS open Forum will look into the W-element
package modeling and add in extra keywords to support this? If yes, when
will it be available?  
 
Looking forward for your reply. Appreciate your attention on this.
 
Regards
Timmy
