The Knowledge Base shows that Vcc (0.9V), and Vccp (1.8V) should come up before Vcceram (0.9V), Vccr_gxb (1.8V), and Vcct_gxb (0.95V). This requires splitting the voltages and adding power switches to sequence the voltages. Is this required?

What are the ramifications of not sequencing these power rails? Does it cause configuration issues, functional problems, or long term reliability issues?
