[SI-LIST] Re: IBIS Model Using Package Model Error

Seshadri,
I just tried appending the package model after "End [Component]" and 
before "[End]".

That seems to work since I now have zero errors.  I'm still very curious 
as to why I cannot reference a separate file.


Another question to the group:
If an IBIS model defines a Package Model does this supersede any lumped 
element data in the R_pin, L_pin, and C_pin fields under [Pin]? 
Or, is this dependent on the simulator?

Thanks,
Chris

Hi,

I am sorry not to have known about that. But did you try including the 
contents of the package file into your IBIS Model to see if that works?

I'm not sure if I agree with that.  Here is the text from the IBIS spec, 
version 4.0 which states that  "If the matching package model is in an 
external .pkg file, it must be located in the same directory as the .ibs 
file". 


|============================================================================= 

| Keyword: [Package Model] 
| Required: No 
| Description: Indicates the name of the package model to be used for the 
| component. 
| Usage Rules: The package model name is limited to 40 characters. Spaces 
| are allowed in the name. The name should include the company 
| name or initials to help ensure uniqueness. The EDA tool 
| will search for a matching package model name as an argument 
| to a [Define Package Model] keyword in the current IBIS file 
| first. If a match is not found, the EDA tool will next look 
| for a match in an external .pkg file. If the matching package 
| model is in an external .pkg file, it must be located in the 
| same directory as the .ibs file. The file names of .pkg files 
| must follow the rules for file names given in Section 3, 
| GENERAL SYNTAX RULES AND GUIDELINES. 
| Other Notes: Use the [Package Model] keyword within a [Component] to 
| indicate which package model should be used for that 
| component. The specification permits .ibs files to contain 
| [Define Package Model] keywords as well. These are described 
| in the "Package Modeling" section near the end of this 
| specification. When package model definitions occur within a 
| .ibs file, their scope is "local", i.e., they are known only 
| within that .ibs file and no other. In addition, within that 
| .ibs file, they override any globally defined package models 
| that have the same name.

Hi,
Did you make sure that you included the contents of the package model in
your IBIS file? You have to include the contents of the package model in 
to
your IBIS file before referencing it. It doenst look up the directory 
where
you have the package file stored. Rather it searches in the IBIS file
itself.
