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 CXT devices require a power-on sequence of VCCINT, VCCAUX, and VCCO. If the requirement can not be met, then
VCCAUX must always be powered prior to VCCO. VCCAUX and VCCO can be powered by the same supply, therefore, both
VCCAUX and VCCO are permitted to ramp simultaneously. Similarly, for the power-down sequence, VCCO must be powered
down prior to VCCAUX or if powered by the same supply, VCCAUX and VCCO power-down simultaneously.
Table 13 shows the minimum current, in addition to ICCQ, that are required by Virtex-6 CXT devices for proper power-on and
configuration. If the current minimums shown in Table 12 and Table 13 are met, the device powers on after all three supplies
have passed through their power-on reset threshold voltages. The FPGA must be configured after VCCINT is applied.
Once initialized and configured, use the XPOWER tools to estimate current drain on these supplies.
