Regarding Decoupling capacitor

Hi

I am developing a new SOC in which different different voltage rails are there.

How do i select the decoupling capacitor for my new SoC development.

The voltage rails mentioned is as below in my application:

  • Core Voltage:1.2V
  • I/O volatge: 1.8V / 2.5V / 3.3V
  • Analog supply :1.6V

Regards
