Adding a run-time phase example

[walkeranderson]

I'm sure it's simple (if you know what you're doing) but could someone please point me to, or include in a response, a simple and complete example of defining a user-defined phase to be inserted into the schedule between the pre_configure and configure phases?

 

Thanks.

Figured this out myself.  In case anyone is interested, here's what I did.

 

 

My goal was to add a run-time phase that I could use for configuring default sequences on sequencers.

 

///////////////////////////////////////////////////////

 

Here's the definition of the new phase

 

class uvm_foo_phase extends uvm_task_phase;

   virtual task exec_task(uvm_component comp, uvm_phase phase);

      my_uvm_sequencer seqr;

      if ($cast(seqr, comp))

        seqr.foo_phase(phase);

   endtask

   local static uvm_foo_phase m_inst;

   static const string type_name = "uvm_foo_phase";

 

   // Function: get

   // Returns the singleton phase handle

   static function uvm_foo_phase get();

      if(m_inst == null)

         m_inst = new;

      return m_inst;

   endfunction

   protected function new(string name="foo");

      super.new(name);

   endfunction

   virtual function string get_type_name();

      return type_name;

   endfunction

endclass

Here's what I added to the build phase of my test component to add it to the run time schedule.

 

         uvm_phase sched = uvm_domain::get_uvm_schedule();

         sched.add(uvm_foo_phase::get(),

                   .after_phase(sched.find_by_name("pre_configure")),

                   .before_phase(sched.find_by_name("configure")));

Here's what I added to my my_uvm_sequencer class

 

  virtual function void foo_phase(uvm_phase phase);

      start_phase_sequence(phase);

  endfunction
