How to change uvm verbosity for an object in component

I encountered an issue when setting verbosity for an object in component. I want to set the verbosity of specific components (uvm_test_top.env.subenv_a) to UVM_HIGH, command line argument is as below:

1.+UVM_VERBOSITY=UVM_LOW

2.+uvm_set_verbosity=*subenv_a*,_ALL_,UVM_HIGH,build,0

The object (object_a) will do some configurations in build phase of component: subenv_a.

I didn't saw the UVM_HIGH info in object_a is printed and the UVM_HIGH info for all the components in component subenv_a will be printed.

Seems that command "+uvm_set_verbosity" just take effect on component,but not object in component.

So what should i do to print UVM_HIGH info for an object in component.

Thanks Ken

Only classes derived from uvm_component have knowledge of their parentage. By knowledge I mean uvm_component is set up to link parents with children as a database that can be traversed via a named hierarchy. You can:

  • Derive your object_a from uvm_report_object instead of uvm_object. Then from your component, do object_a_h.set_report_handler(get_report_handler);. Now all messages from object_a appear as if they came from your component and share the same report settings.
  • Pass this as a context to your object_a, and use the uvm_info_context() macros instead of uvm_info. This has the same effect as above.
  • Use a unique message ID in object_a and add a extra +uvm_set_verbosity switch for that ID.
  • Derive your object_a from uvm_component instead of uvm_object and make your component its parent. This might be the simplest solution, but has the most overhead if there many of these objects.
