Power Supply
+1.0V
+1.8V
+3.3V
+1.5V
VREF,VTT(+0.75V)
CCIP(+3.3V)
MGTAVTT(+1.2V)
MGTVCC(+1.0V)
Because the power supply of Artix-7 FPGA has the power-on sequence
requirement, in the circuit design, we have designed according to the power
requirements of the chip, and the power-on is 1.0V->1.8V->(1.5 V, 3.3V, VCCIO)
and 1.0V-> MGTAVCC -> MGTAVTT, the circuit design to ensure the normal
operation of the chip.
The power circuit on the AC7A035 FPGA core board is shown in Figure
