Power-On Power Supply Requirements
Xilinx® FPGAs require a certain amount of supply current
during power-on to insure proper device initialization. The
actual current consumed depends on the power-on ramp
rate of the power supply.
The power supplies can be turned on in any sequence,
though the specifications shown in Table 5 are for the
recommended power-on sequence of V_CCINT, V_CCAUX, and
V_CCO. The I/O will remain 3-stated through power-on if the
recommended power-on sequence is followed. Xilinx does
not specify the current or I/O behavior for other power-on
sequences.
Table 5 shows the minimum current required by Virtex-5
devices for proper power-on and configuration.
If the current minimums shown in Table 5 are met, the
device powers on properly after all three supplies have
passed through their power-on reset threshold voltages.
The FPGA must be configured after V_CCINT is applied.
Once initialized and configured, use the XPOWER tools to
estimate current drain on these supplies.

Notes:
1. Typical values are specified at nominal voltage, 25°C.
2. The maximum startup current can be obtained using the
XPOWER Estimator (XPE) or XPOWER Analyzer (XPA) tools
and adding the quiescent plus dynamic current consumption.
