Uvm factory registration disambiguation

[bradpinn]

Hello

 

Kindly support with the following question:

Considering a verification environment that imports 2 packages, pkg_A and pkg_B.

Both packkages contain some common class definitions (i.e. same class name, class properties, etc.):

 

pkg_A.sv                                                               pkg_B.sv

class some_name;                                                class some_name;

 `uvm_object_utils(some_name)                           `uvm_object_utils(some_name)

,,,,                                                                                      ...

 

This makes the same class name to be registered to the factory twice, leading to the :

UVM_WARNING @ 0: reporter [TPRGED] Type name some_name already registered with factory. No string-based lookup support for multiple types with the same type name.

Consider that both pkg_A and pkg_B have numerous class with same name.

How can this be fixed?

Thank you

The easy answer is don't wildcard import packages, ever! Except for uvm_pkg.

As for `uvm_object_utils , if you add package scoping that'll resolve your issue.

`uvm_object_utils(pkg_A::some_name)
