This time requires adjustment whenever a signal standard other than LVCMOS25 with 12 mA drive and Fast slew rate is assigned
to the data Output. When this is true, add the appropriate Output adjustment from

When reading from the
Output Flip-Flop (OFF), the
time from the active transition
at the OTCLK input to data
appearing at the Output pin
The time it takes for data to
travel from the IOB’s O input
to the Output pin
The time it takes for data to
travel from the O input
through the OFF latch to the
Output pin
Time from asserting the
OFF’s SR input to
setting/resetting data at the
Output pin
