Overriding a parameter

In reply to dave_59:

Thanks for the pointers, Dave. Is it possible to change the value of the parameter in an extended class and then override the class using a plusarg?
eg:

class A;
   parameter int WIDTH = 8;
endclass

class A1 extends A;
    parameter int WIDTH = 16;
endclass

run the test with +uvm_set_type_override=A,A1
