Description
Another type_id case that got added to a future UVM release, as noted in #5826, but different case.
Below gives: `
%Error: Package/class for ':: reference' not found: 'type_id'
18 | t = BUSTYPE::type_id::create("t");
@kbieganski analyzed (thanks) and: "This case seems to break because of the default type parameter. uvm_object doesn't have type_id, but we try to link BUSTYPE::type_id (=uvm_object::type_id) in LinkDot which fails. We can defer it until after V3Param but then the instance with default params is still around, so we revisit it and have the same problem. We'd have to delete the default instances if unused after V3Param. I'm not familiar enough with that stage to know how difficult that is.
Which also sounds related to #4581 et al.
