Warning "Type already registered with the factory"

[icarus035]

Hi, I have the following problem:

I have 2 classes:

class1 extends uvm_monitor

`uvm_component_utils_begin(class1)

...

`uvm_component_utils_end

...

endclass

and second class which extends the previous:

class2 extends class1

`uvm_component_utils(class2)

...

endclass

I am using Cadence irun tool (ncverilog, ncelab), the latest one - incisive 10.20.029

I see warning: Type "class2" is already registered with the factory.

I tried using `uvm_component_param_utils instead (in both classes) because this seemed to help in some previous cases I had with parameterized classes, but here the result is the same.

If I remove `uvm_component_utils macro from class2, then when I try to override class1 with class2 from the test, I get error that class2 is not registered with the factory.

Please, any ideas what causes this warning and how to remove it?

Thanks.

hi,

im not aware of an issue in that area. the message basically says that you are trying to register a string type name for a class in the factory but a class with the same name has already registered that typename. here are some points you may want to check:

1. you will see this warning

- if you declare a class with the same name in different scopes (same class name in different packages, different modules/classes )

- if you include the file with the class decl multiple times

- if you use a param class and not use the _param_ version of the macros

2. you might cross check with the examples in the examples directory

I seems I have included the file with the class two times.

Problem solved. Thanks.
