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.
Virtex-6 devices require a power-on sequence of V

have passed through their power-on reset threshold voltages. The FPGA must be configured after V
Once initialized and configured, use the XPOWER tools to estimate current drain on these supplies.
