To take advantage of the power management switching of power domains, your design must keep some discrete power rails. This allows individual rails to be powered off with the power domain switching logic at the cost of using additional voltage regulators or regulator outputs. For more information, see this link in the UltraScale Architecture PCB Design User Guide (UG583).
