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
(2)

and
Time from the active transition at the OTCLK
input of the Three-state Flip-Flop (TFF) to when
the Output pin enters the high-impedance state
Time from the active transition at TFF’s OTCLK
input to when the Output pin drives valid data
Time from asserting the Global Three State
(GTS) input on the STARTUP_SPARTAN3A
primitive to when the Output pin enters the
high-impedance state
Time from asserting TFF’s SR input to when the
Output pin enters a high-impedance state
Time from asserting TFF’s SR input at TFF to
when the Output pin drives valid data
