I know this is from 3 years ago, but....

Which clock do I choose for the REF_CLK_GXBL?? for the transceiver in that same IO Bank, B or T? Do I connect both to the same clock source? Do I only connect one and the other to ground? Does it matter which one I choose?

Why does the FPGA that has all its connections in a ball grid array on th bottom have a clock input labeled as Top or Bottom?
