Can cmod s6 be used to drive VGA

[grf]

Sorry if this is a dumb question.

 

I am fairly new to FPGA's, I have had a Basys2 for a while and just got a Cmod s6 to tinker with  

 

I note that the clock on the cmod s6 is only 8MHz.  I would ideally like to drive VGA so need 25Mhz. From the schematic I don't think I can easily introduce my own external clock (crystal), but was intrigued by this statement in the docs.  

 

 "The 8MHz clock, called “FPGA-GCLK”, can be used with the FPGA’s clock manager to create a wide range of frequencies, even beyond 200MHz"

 

How would one go about generating (say 25MHz)?  And should I be expect to be able to drive VGA with a generated clock.

 

Thanks in advance.

Thanks Alex. 

 

That worked.  I tend not to use ISE/IDE (command line guy) but finally worked out the coregen magic options

I think you can use DCM to generate the 200MHz clock. You can search that task function in xilinx ISE or Vivado.

I don't think it's a dumb question... I'd like to also find out if it's possible.
