How do we determine here which signal will be assigned power net class and which will be assigned signal net class?

  1. Usually anything that powers the IC, powers a transistor/MOSFET or supply power to drive a high current component is considered the power net.

    Signal nets are somethings that carries smaller current to turn on transistor/MOSFET gate, logic decision taken by a IC, or basically any signal that carries information is considered as the Signal net.

    According to your attachment  :

    • VDDA, VSSA, VDDB, VSSB, +5v, GND can be considered as power nets
    • Disable, PWM signals can be considered as signal nets
