I have problem with functional simulation with

In the tutorial it says In Quartus, there are two types of simulation. 1) Functional 2) Timing For Functional, you do not need a schematic. Functional means there are zero delays...only...

Now I know what is wrong. The tutorial is not so clearly. Man must do Simulator tool, click on the Generate funtional simulation netlist, then do start simulation.

But then I get another problem. I give CLOCK 20.8ns period to clk, give 0-40ns force low(0) to reset_b, give clock 400ns period and 200ns phase to PBSwitch. Then I do the start simulation. I get output of Led is "1111". It does not change. It should be output like "1111","1110","1101"....

Do you know what is wrong with my vector wave form?
