Hi,
i am trying to conduct a simple test for generating a 10Mhz clock with clock wizard using the fixed 200Mhz clock to divide down to 10Mhz and then map the signal to a J1 connector pin so i can see the clock signal on the scope.
Take a look at the xdc posted below. What am i doing wrong in the xdc file?
When i use a xilinx spartan 7E board it has a dedicated board differential clock which i can pin to a clock wizard and don’t have to declare anything in xdc file except the output pin mapped to a PMOD pin. So what do i have to do to get the right declaration in xdc file? I am just trying to brin g in fixed clk into wizard and map its output to pin in J1 connector that is on extension board. I see nothing on scope.
Thanks
