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 rec-
ommended power-on sequence of VCCINT, VCCAUX, VCCO.
Xilinx does not specify the current for other power-on
sequences.
Table 5 shows the minimum current required by Virtex-4
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.
Once initialized and configured, use the XPower tool to esti-
mate current drain on these supplies.
