New ContributorThe 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?

Frequent ContributorThanks @Busy Just to top up some info for @BAdam1 , you may also want to refer to the https://www.intel.com/content/www/us/en/programmable/documentation/vua1487061384661.html#qwj1528888537561
You will need to follow the sequencing, to guarantee the reliability and not to damage the device.
