The PS and PL power supplies are fully independent. PS power supplies (VCCPINT, VCCPAUX, VCCPLL, VCCO_DDR, VCCO_MIO0, and VCCO_MIO1) can be powered before or after any PL power supplies. The PS and PL power regions are isolated to prevent damage. The recommended power-on sequence is VCCPINT, then VCCPAUX and VCCPLL together, then the PS VCCO supplies (VCCO_MIO0, VCCO_MIO1, and VCCO_DDR) to achieve minimum current draw and ensure that the I/Os are 3-stated at power-on. The PS_POR_B input is required to be asserted to GND during the power-on sequence until VCCPINT, VCCPAUX and VCCO_MIO0 have reached minimum operating levels to ensure PS eFUSE integrity.
