All control signals can be inverted at the IOE. No programmable delay chains are shown in this diagram.
The OE signal is active low, but the Quartus II software implements this as active high and automatically adds an
inverter before input to the A
The A
This select line is to choose whether the OE signal should be delayed by half-a-clock cycle.
The B
The tristate enable is active low by default. You can design it to be active high. The combinational control path for
the tristate is not shown in this diagram.
You can also have combinational output to the I/O pin; this path is not shown in the diagram.
