Uvm build phase

UVM
1

In uvm,

virtual function void build_phase(uvm_phase phase);
      super.build_phase(phase);  // Calls my_monitor's build_phase first
      $display("Building my_custom_monitor with additional setup...");
      // Custom behavior for this specific monitor
   endfunction
endclass

why we mentioning build_phase as virtual?
In uvm base class, build_phase is virtual,so that it is intended to be overridden in the custom uvm class. But again in custom class also why it is need to give a virtual keyword in build_phase?

In SystemVerilog, if the base class declares a method virtual, the method is always virtual in all derived subclasses. The virtual keyword is optional.

Hi Dave,
Wanted to check with you if my understanding is correct

Since the respective phases are defined as virtual within uvm_component class,
during a successful factory override this helps in calling the respective phases within the overridden component

You’re right about your understanding of the phases. I suggest you try a small example to confirm this understanding for yourself.
