The numbers in this table are tested using the methodology presented in
Table 8
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
