Stratix GX devices have an I/O interconnect similar to the R4 and C4
interconnect to drive high-fanout signals to and from the I/O blocks.
There are 16 signals that drive into the I/O blocks composed of four
output enables io_boe[3..0], four clock enables io_bce[3..0], four
clocks io_bclk[3..0], and four clear signals io_bclr[3..0]. The
pin’s datain signals can drive the IO interconnect, which in turn drives
the logic array or other I/O blocks. In addition, the control and data
signals can be driven from the logic array, providing a slower but more
flexible routing resource. 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 regional, global, or fast regional clocks (see
“PLLs & Clock Networks” on page

Each IOE contains its own control signal selection for the following
