  1. Does an abstract class (virtual class ....), which extends from uvm_object, benefit from using uvm utility macros (`uvm_component_utils, `uvm_object_utils)? As I understand, `uvm_component_utils and `uvm_object_utils are used to register a class w/ the factory so objects of that class can be overridden. But, because an abstract class cannot be instantiated, it cannot be overridden. Is that assessment correct? Are those utils macros doing smthg else besides allowing for 'overriding' capability? (Although I have looked at them, I know I don't fully understand all they're used for.) than
  2. Hi, all I want to use the factory mechanism to write one reusable test, this is the codes class my_test #(parameter TSID=0) extends uvm_test; typedef my_test #(TSID) this_typ; typedef uvm_component_registry #(my_test #(TSID), $sformatf("my_test%0d", TSID)) type_id; static function type_id get_type(); return type_id::get(); endfunction : get_type function new(string name = "my_test", uvm_component parent=null); super.new(name,parent); endfunction : new ... endclass But I met such a compile error: Error-[NCE] Non-constant expression The following expression
  3. I'm attempting to do an instance override on a parametrized type in UVM, but I can't seem to set a correct path to the instance I want to override. The code below factory.set_inst_override_by_type(typical_item#(1, 1)::get_type(), typical_item_1#(1, 1)::get_type(), override_path); works if override_path == "*" which is matching everything and thus doing in essence a type override - not what I want. If I try to be more specific (even entering something like uvm_test_top) no instances are overridden. Is there a way to find out the correct instance path to some sequence so I can use it i
