There are 32 control and data signals that feed each row or column I/O
block. These control and data signals are driven from the logic array. The
row or column IOE clocks, io_clk[7..0], provide a dedicated routing
resource for low-skew, high-speed clocks. I/O clocks are generated from
global or regional clocks. Refer to
