Virtex-E Switching Characteristics
All devices are 100% functionally tested. Internal timing parameters are derived from measuring internal test patterns. Listed
below are representative values. For more specific, more precise, and worst-case guaranteed data, use the values reported
by the static timing analyzer (TRCE in the Xilinx Development System) and back-annotated to the simulation net list. All
timing parameters assume worst-case operating conditions (supply voltage and junction temperature). Values apply to all
Virtex-E devices unless otherwise noted.
IOB Input Switching Characteristics
Input delays associated with the pad are specified for LVTTL levels. For other standards, adjust the delays with the values

Notes:
1.
A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed “best-case”, but
if a “0” is listed, there is no positive hold time.
2.
Input timing i for LVTTL is measured at 1.4 V. For other I/O standards, see Table 3.
