PS_INIT_B INIT_B relationship in MPSoC

[perencia-wc]

In a MPSoC I'm confused between PS_INIT_B and the fpga INIT_B signals. How are they related? For what I've read in UG1085 I understand that PS_INIT_B and INIT_B are basically the same, except that it is also related to the LBIST PS Boot sequence.

Thanks.

they are the same since PL is controlled by the PS, so ZynqMP device calls it as PS_INIT_B.
I don’t remember there are individual PS_INIT_B and INIT_B signals from ZyqnMP device.
