Power sharing - FPGA & HPS power supply

Dear community, As you know, the HPS unit and the FPGA unit of the Cyclone V SXF need different voltage supplies, for instance 1.1 V for the core 1.5 V for the DDR3 and corresponding ban...

When share power supply, not only the FPGA and HPS, but also other chips whose work frequence is very high, will be effected by each other. When we design a high-speed PCB(such as dac or adc), we always separate power supplies for each chips. Maybe you can learn some knowledge about digital and analog circuit. Then you can understand it better.
