How to up or down the input clock to creat other frequencies?

     I could get a clock 50MHz from the C9 pin on the spartan-3E board. If I need a 100MHz clock for my design, how could I get it through system generator 10.1? In ISE, it's easy done to use DCM primitive in VHDL or Verilog. But in system generator, I don't know how to realize it.

     I know I can get 5MHz through 'Counter' module. And are there other ways to get 5MHz in dsp when the input clock on pin C9 is 50MHz?

Re: How to up or down the input clock to creat other frequencies?

       Can any body help me?  We could find way to down input clock (by 'Counter' or something else), but up input clock isn't easy. That's what I want to know firstly.
