When a PCB board features multiple digital/analog modules, the ordinary solution is to divide digital/analog modules. Why?

The reason for dividing digital and analog modules is that noise is usually generated at power and ground at the switching of high and low potential and the extent of noise is related with signal speed and current amount. If analog and digital modules are not divided and the noise generated by digital module is larger and circuit at analog area is similar, even if analog and digital signals don’t come across, analog signals will still be affected by noise.
