Preliminary
Guaranteed Input and Output Parameters (Pin-to-Pin)
All values listed below are tested directly, and guaranteed over the operating conditions. The same parameters can also
be derived indirectly from the Global Buffer specifications. The XACT delay calculator uses this indirect method, and may
overestimate because of worst-case assumptions. When there is a discrepancy between these two methods, the values
listed below should be used, and the derived values should be considered conservative overestimates.

Note:
1. These measurements assume that the flip-flop has a direct connect to or from the IOB. XACT-Performance can be
used to assure that direct connects are used.
2. When testing outputs (fast or slew-limited), half of the outputs on one side of the device are switching.
3. Die-size-dependent parameters are based upon XC5210 characterization. Production specifications will vary with array
size.
