Cyclone 10 GX: If I have a 1.8 VCCIO Rail and a 3.0V VCCIO Rail can I ramp the 1.8 VCCIO Rail together with power group 2 in the power up sequence?

Cyclone 10 GX Pin Connection Guideline PCG-01022 2017.11.06 Figure 2 shows a supply sharing example. Regarding Power Up Sequence: If I have a 1.8 VCCIO Rail and a 3.0V VCCIO Rail can I ramp the 1.8 VCCIO Rail together with VCCPT in power group 2 and afterwards 3.0 VCCIO in group3? Or do I have to ramp up 3.0 VCCIO and 1.8 VCCIO together in group3?

    Hi Marco,

    You may ramp 1.8V VCCIO with VCCPT since they are sharing the same voltage and regulator.
