Sorry,There is a mistake of sentences, so I rewrite as follows.

Is there a rule of the power supply sequence in ArriaIIGX?

In altera arriaIIGX eva. board,VCCA,VCCA_PLL(2.5V) are turned on after VCC,VCC_PLL(0.9V).

PGOOD of VCC,VCC_PLL power supply is connected to EN of VCCA,VCCA_PLL power supply .

Should I observe this rules?
