how to check the set_type_overide is right

[dmq0420]

I had created 2 classes like following:

class a;

class b extends a;

I'm using

a::type_id::set_type_override(b::get_type());

to do the type override.

However, I found it didn't work. I added the post_randomize and some display information in the class b. But it never display anything.

----------------------------

I use the factory.print(), it show the following:

Type Overrides:

Requested Type Override Type

----------------------- ------------------------------------------

a b

Does anyone know this problem?

This is just a guess, so I haven't checked it...

Firstly both a and b must be registered with the factory for the factory t be able to print it, and secondly the field which is to be overidden must also be registered with the factory.

So say you wanted to override component a with component b in the enviromnent env.

component a must include : `uvm_component_<param>_utils (a)

component b must include : `uvm_component_<param>_utils (

Environment must include :

`uvm_component_utils_begin(env)

...

`uvm_field_object(inst_a, UVM_DEFAULT)

...

`uvm_component_utils_end

I think this will work.
