Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems. It is most commonly used in the design and verification of digital circuits at the register-transfer level of abstraction. It is also used in the verification of analog circuits and mixed-signal circuits, as well as in the design of genetic circuits.. Read more on Wikipedia...


Example from Riju:
module main; initial begin $display("Hello, world!"); end endmodule
Example from hello-world:
module main; initial begin $display("Hello World"); $finish; end endmodule
Example from the Hello World Collection:
/* Hello World in Verilog. */ module main; initial begin $display("Hello, World"); $finish ; end endmodule

Example from Wikipedia:
initial a = 0; initial b = a; initial begin #1; $display("Value a=%d Value of b=%d",a,b); end
