Time is written in integer or fixed point format, followed without a space by a time unit. The time literal is interpreted as a realtime value scaled to the current time unit and rounded to the current time precision. Following are time literals examples.

• 1ns
• 1.4ps
• 0.01ns

  1 `timescale 100ps/10ps
  2 module time_literals ();
  3 
  4 time a;
  5 initial begin
  6   $monitor ("@ %g a = %t", $time, a);
  7    #1  a =  1ns;
  8    #1  a =  0.2ns;
  9    #1  a =  300ps;
 10    #1  $finish;
 11 end
 12 
 13 endmodule

 @ 0 a =                    0
 @ 1 a =                  100
 @ 2 a =                   20
 @ 3 a =                   30
