Hi everyone I am a self learner of UVM started for last 2 days have tried a simple code in edaplayground but having error in `uvm_info.I know its very basic but crucial for me and I am enjoying my evolution phase in learning.Any help will be appreciated

//============ code starts here =========//

module automatic test_program;
  import uvm_pkg::*;
class hello_world_test extends uvm_test;
  //register to uvm factory 
  `uvm_component_utils(hello_world_test)
  //let the uvm make the constructor 
  function new(string name,uvm_component parent);
    super.new(name,parent);
  endfunction
  //rum phase as the initial block in SV
  task run_phase(uvm_phase phase);
    `uvm_info("DEMO","Hello world",UVM_MEDIUM);
  endtask 
endclass


initial begin 
    run_test();
end 
  
endmodule

//================== end ===================//

In reply to designMaster:

Since you are learning, I’ll leave it to you to figure out the solutions:

  • The UVM macros (uvm_info, uvm_component_*) are defined in a file. Perhaps you should `include it somewhere?
  • How does run_test() know what test to run?
