IBIS File error

[GeoKnight]

Hello,

I have a doubt on the following.

When I run golden rule check of the IBIS file it gave me error saying

"Pin Mapping pulldown_ref entry 'GND' is not connected to at least one pin whose model_name is POWER or GND"
"Pin Mapping pullup_ref entry 'VCCO_38' is not connected to at least one pin whose model_name is POWER or GND"

Can you explain what this means and how to resolve this issue. Because when i see the ibis file it is clearly those pins have a model name

I have attached the ibis file below.

I can't really help with this, I am not sure. If this is for simulations, maybe this can help or at least give you an idea? https://youtu.be/-t25gJIDQNo
