|
|

1 module clocking_default();
2
3 logic clk = 0;
4 always #10 clk++;
5
6 // Specify the default clocking
7 default clocking test @ (posedge clk);
8
9 endclocking
10
11 initial begin
12 $display("%0dns is current time",$time);
13 // Any ## is evaluated with respect to default clock
14 ##100 ;
15 $display("%0dns is current time",$time);
16 $finish;
17 end
