The incremental values for the settings are generally linear. For exact values of each setting, please use the latest version of
Quartus II software.
The minimum and maximum offset timing numbers are in reference to setting "0" as available in the Quartus II software.
The fast corner timing parameter is for commercial devices.

version of Quartus II.
The 12 μA programmable current strength for 1.2 V and 1.2-V HSTL Class
I I/O standard is not supported at row I/Os. The 1.2-V HSTL Class II
standard is only supported at column I/Os. PCI and PCI-X do not
support programmable current strength.
For more information about programmable current strength, please refer
to the
Dedicated LVDS, mini-LVDS, PPDS, and RSDS I/O standards are
supported at row I/Os. External resistor networks are required if the
differential standards are used as output pins at column banks. LVDS I/O
standard is supported at both input and output pins. PPDS, RDSD, and
mini-LVDS standards are only supported at output pins.
