It seems there is something wrong with'##2 rtr_io.cb.reset_n <= 1'b1' in Test Program since compiling tool sends error that 'a default clocking block must be specified to use the ##n timing statement'. Can someone help to correct the test program? Thx!

In reply to WenChicken:

You can have any number of procedural delays before any procedural statement. The procedural delay is unrelated to the procedural statement that follows it.

##2 $display("Hello");

In order for ##2 to work, it needs a default clocking statement in the same scope where it appears.
