Hi everyone,
I'm trying to interface with QDRII+ and I use NetFPGA-1G CML Kintex-7
I have done the simulation, it works just fine, however when I implement to the real board, the calibration is failed.
I have 2 questions:
Do I need to use exact frequency for sys_clk_p/n (it requires 450.045 MHz)?
In the NetFPGA board, I just see 1 pair system_clk_p/n (200MHz), I'm supposed to use it as clk_ref_p/n, what should I use for sys_clk_p/n(450.045MHz)
Thanks in advance.
