You need to be much more explicit about what you want to do. When do you want the copy to happen? Or is it that you always want access to the 'in' member of class. You can't do anything in OOP without showing the procedural methods that acts upon the data. If you are using the UVM, it might help to show the UVM classes there represent. There might be an existing UVM mechanism to help you out.

Also, a great place to help you with UVM issues is on the forums at https://verificationacademy.com/

First of all, both the classes A and B are no where related. I mean to say relation in terms of inheritance. When you talk about copy method of UVM, copy method attached with the object must accepts the same type, i mean base type should be same.

Here you can write a different copy method [conventional] which accepts object of class A type. like

copy_conv (A b); inside the B class. then probably you can call like B.copy_conv(a);

Hope this helps.
