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

This clock-to-output time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the Global Clock
Input or a standard other than LVCMOS25 with 12 mA drive and Fast slew rate is assigned to the data Output. If the former is true,
add the appropriate Input adjustment from
DCM output jitter is included in all measurements.
For minimums, use the values reported by the Xilinx timing analyzer.
