Figure 40. Synchronous Bidirectional Pin External Timing
Notes:
(1)
The output enable and input registers are LE registers in the LAB adjacent to a bi-
directional row pin. The output enable register is set with “Output Enable Routing=
Signal-Pin” option in the Quartus II software.
(2)
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 bi-directional pin. The exact position where zero
hold occurs with the minimum setup time, varies with device density and speed
grade.
Table 35 describes the fMAX timing parameters shown in Figure 36.
