Hi
I am using Vivado 2015.1 and I try to use a DDR3 RAM, connected to the Artix-7. I have two input clocks, 25 Mhz and 27 Mhz.
Any body can help me to assign proper frequencies for system clock and reference clock.
I tried to use internal PLL of the FPGA, but somebody told me in MIG the input clock must be external and I can not use PLL.
