Input delay from the pin to the
internal cells
Input delay from the pin to the
input register
Delay from the output register to
the output pin
Input delay from the
dual-purpose clock pin to the
fan-out destinations
Notes to
(1) The incremental values for the settings are generally linear. For the exact values of each setting, use the latest version of the Quartus II software.
(2) The minimum and maximum offset timing numbers refer to the 0 setting available in the Quartus II software.
