Calling DUT Memory initialisation task from uvm_test

UVM

Hello,

I have a task in top.sv which initialises a Memory inside DUT with the contents of the init.mem file.

How can I call this task from uvm_test ?

Thanks

You cannot call any TB task directly in the uvm_test.
You can do it in multiple ways.

  1. use uvm event pool
  2. Static class.

Using uvm_event_pool:


//In your tb file 
import uvm_pkg::*;
initial begin
  uvm_event evt;
  uvm_event_pool ev_pool;
  ev_pool = uvm_event_pool::get_global_pool();
  evt = ev_pool.get("EVT_DO_INIT_MEM");
  forever begin
    evt.wait_trigger();
  end
end
//In your uvm_test 
  uvm_event evt;
  uvm_event_pool ev_pool;
  ev_pool = uvm_event_pool::get_global_pool();
  evt = ev_pool.get("EVT_DO_INIT_MEM");
  //Call this when you want to initialize memory
  evt.trigger();
  end

Why do you want to do this from your testbench? This would make sense only when the initialization is test dependent.
