Table 1 shows the minimum current, in addition to I_CCQ maximum, required by each Artix UltraScale+ FPGA for proper power-on and configuration. If these current minimums are met, the device powers on after all supplies have passed through their power-on reset threshold voltages. The device must not be configured until after V_CCINT is applied. Once initialized and configured, use the Xilinx Power Estimator (XPE) to estimate current drain on these supplies. The XPE tool (download at https://www.xilinx.com/power) is also used to estimate power-on current for all supplies.
