The incremental values for the settings are generally linear. For exact values of each setting, use the latest version
of the Quartus II software.
The minimum and maximum offset timing numbers are in reference to setting “0” as available in the Quartus II
software.
The value in the first row represents the fast corner timing parameter for industrial and automotive devices. The
second row represents the fast corner timing parameter for commercial devices.
The value in the first row is for automotive devices. The second row is for commercial devices.
