I'm setting power-up sequence for Arria-10 in a new board. As it is written in Intel's specification "AN 692: Power Sequencing Considerations for Intel® Cyclone® 10 GX, Intel® Arria® 10, and Intel® Stratix® 10 Devices", group 3 ramp-up and group 2 ramp-up can be combined "if the two groups share the same voltage level and the same voltage regulator as Group 2 power rails VCCIO, VCCPGM, and VCCIO_HPS".
In my board, VCCIO is supperated to different voltage levels (1.2v, 1.8v, 3v). VCCIO_HPS is not used.
My question is, can I combine the ramp-up of VCCPGM and the 1.8v of VCCIO with group 2, and ramp the rest of the VCCIOs (1.2v, 3.0v) as group 3? Or, do I have to ramp VCCPGM and the 1.8v-VCCIO with group 3?
