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?

This is for a Cyclone 10 GX device. The device part number is 10CX085YU484I5G.

Intel recommends power sequencing... If you do not respect them, correct behaviour is not guaranteed and the causes of the dysfunctions may be difficult to detect.

Thanks @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#qwj15288885...

 

You will need to follow the sequencing, to guarantee the reliability and not to damage the device.
