IBIS model for FGG484 Package parasitic Missing

[shashank.d@siennaecad.com]

I am using XC7A100TFGG484 in one of my design. I downloaded IBIS model for the same.

But the model does not have the Package parasitic for FGG484 Package.

How to include this in IBIS model. Kindly address the issue.

Further,

The FGG prefix denotes the lead vs non lead material, so any F**484 package is identical (leaded vs, non-leaded does not affect the IBIS result).

shashank.d@siennaecad.com The downloaded folder will have the FGG484.pkg file. Include the contents of the .pkg file into the IBIS file and you will have the package details of the part.

Hi gnarahar,

Thanks for your reply.

I want to know how to add Package file data in IBIS file. Is there any specific format we have to follow?

s,

Yes.  IBIS is a standard.  The format must follow the standard.

shashank.d@siennaecad.com You need to add the .pkg details to the end of the IBIS model. Check the attached IBIS file for reference. Check from Line 5777

Make sure the correct Package is selected in the [Package] section of generic Model you downloaded. Line 33 - 39 in the attached model. 

If you have the design, you can generate the design specific IBIS model using write_ibis Tcl command in Vivado. This will be much easier.
