I have seen the attached file there where you want to make a 16-bits up counter, what is the things does not work? Is it the simulation or the compilation. Besides, the weird which green symbol there is just a setting displayed whenever you select option in parameter setting.
From the counter14_schematic.jpg, What I can tell is the the input pins clock is not connected. Try to connect the input first and also I not sure if that is the correct way to insert all 16-bits output pins.
The input pins clock (mclk_in) is connected by the output pin (mclk_out) to which co of PLL03_50 is connected and a hardware jumper on the board.
This is the same as the mclk_in signal in the attached simulation wave picture.
In addition, a schematic and simulated wave picture are attached.
Is there any more material you need to review counter14?
