How to read UVM_TESTNAME using uvm_config_db

UVM

Hi,
Is it possible to read value in +UVM_TESTNAME using the uvm_config_db?
Something like this:
string testname;
void’(uvm_config_db#(string)::get(null,“*”,“UVM_TESTNAME”,testname));

The testname is not stored in the config_db(), but you can use $value$plusargs:

module testbench();

  string tn;
  
  initial begin
    if ($value$plusargs("UVM_TESTNAME=%s", tn))
      $display("value was %s", tn);
    else
      $display("+UVM_TESTNAME= not found");
    #100 $finish;
  end
endmodule

Thanks a lot, that worked!

I had earlier tried the following:
if ($test$plusargs(“testname” ) begin
…
end
But that did not work.

Note that a UVM testname can also be given as an argument to run_test("testname") without a +UVM_TESTNAME switch (The switch takes precedence).

uvm_top.find("uvm_test_top").get_type_name() works either way.

Many Thanks Dave for your response. The run_test() call in the TB I am working on does not specify any “testname”. Instead, the testname gets passed to this function via command line options.
So, then will uvm_top.find(“uvm_test_top”).get_type_name() still work?
I haven’t tried it out, but can do so and see.
At least it will be another alternate way of accessing the testname.
