Hello World example run error?

In reply to S.P.Rajkumar.V:

Hello Sir,
Thanks for the reply.
Is this command correct?
qverilog -f uvm_hello_world.f

If yes, whats the purpose of this command? At many sites on web this command has been used but it doesnt seem to work? Rather "qverilog uvm_hello_world.sv " command works.
Can u plx put some light on it?
Thanks,
Swapnil
