How to get a 20 Mhz clock on Xilinx Virtex-5 FPGA XC5VLX50T-1FFG1136 (ML505 kit)

sir,

i am trying to make a verilog code . After the synthesis process is done . the maximum clock frequency that my design can work on comes out to be 20 Mhz. But the oscillator gives three clock frequencies only 33 mhz , 27 mhz and 100 mhz (as in user guide). i tried to take the 100 mhz clock and divide it by 5 but the design won't work.. please help me here

Replace the oscillator on your board with a 20 MHz oscillator.

----------------------------Yes, I do this for a living.
