The output enable and input registers are LE registers in the LAB adjacent to a
bidirectional row pin. The output enable register is set with “Output Enable
Routing= Signal-Pin” option in the Quartus II software.
The LAB adjacent input register is set with “Decrease Input Delay to Internal Cells=
Off”. This maintains a zero hold time for lab adjacent registers while giving a fast,
position independent setup time. A faster setup time with zero hold time is possible
by setting “Decrease Input Delay to Internal Cells= ON” and moving the input
register farther away from the bidirectional pin. The exact position where zero hold
occurs with the minimum setup time, varies with device density and speed grade.
