The numbers in this table are tested using the methodology presented in
Table 10
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 OCLK 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
Time from asserting the OFF’s SR
input to setting/resetting data at the
Output pin
Time from asserting the Global Set
Reset (GSR) input on the
STARTUP_SPARTAN3A primitive to
setting/resetting data at the Output pin
