Assuming a source file of hello_world.v and a top level module of hello_world. The code can be run using various simulators. Most simulators are compiled simulators. They require multiple steps to compile and execute.
Generally the
First step is to compile the Verilog design.
Second step is to ...
The program outputs Hello World! to standard output.
module HELLO_WORLD(); // module doesn't have input or outputs
initial begin
$display("Hello World");
$finish; // stop the simulator
end
endmodule
