The numbers in this table are tested using the methodology presented in
Table 77
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
For minimum delays use the values reported by the Timing Analyzer.
