  • Why should you need a DCM to divide your clock by 500,000 - you can do this in the fabric easily.

     

    If you want to understand the DCM then I suggest you start by reading the manual - (ug382.pdf on Xilinx's website (you should read the data sheets for the chip you are using as well)).

     

    If there are things in the guide or data sheet that you don't understand then come back and ask about them. Expect to spend at least a day getting enough of  a feel of the DCM to think about using it.
