how to override classes inside a specific class (not a specific instance)

[LiorKoren]

Hey,

Is there a way to overide classes within another class?

e.g.

class a_driver extends uvm_driver

endclass

class a_agent extend uvm_agent

a_driver driver ;

endclass

class b_agent extend uvm_agent

a_driver driver ;

endclass

class b_driver extends a_driver

endclass

and I want to use b_driver instead of a_driver ONLY in b_agent classes.

If you know the instance names of all b_agent classes, you can override it using the factory.

If you don't know the instance names, you need to create a new "bb_agent" that overrides its driver type to use b_driver using the factory before calling super.build_phase(), then do an override-by-type of b_agent with bb_agent.

Even if you don't know all the instance names you can use a wildcard to match the instances in b_agent
