How to use Differential System clock of Kintex-7 in my design where the clock is single-ended.

Hi,
I am using Kintex-7 KC705 board. In my design I hThen How can I use the differential clock source of FPGA. Can I directly connect the sys_clk_p to my deisgn clock?? Or I have to convert the differential clock to single ended clock?? Thanks in advance. :)

yes you can convert differential clock to single ended in the fpga by using IBUFDS

check for libararies guide in the following link for the usage of Ibufds

Yes I saw that. But I want to know whether the sys_clk_p will work or we must have to use IBUFDS?
