Find_objects -object_type model in UPF2.1

Hi:
I am reading the 1801-2013 spec, I saw the object_type model in find_objects command. Can anyone help to provide examples what a model is referred to?

thanks

Until the UPF community becomes large enough to support its own forum, you will probably need to contact your EDA vendor directly for support, or try asking here.
