How can I get an early power estimation for Cyclone10LP to compare the standard power consumption ('Y' marking in device code) versus the lower power consumption ('Z' marking in device code)?
I've downloaded the latest EPE a minute ago but I can't find an option to change that setting.
You will be able to select the VCCINT voltage in the EPE depending on the Device/Package/Temperature Grade you select.
A quick tips: Use the Quartus device setting as reference to know which device support 1.0V and 1.2V.
Below screenshot is an example: 10CL006 E144 Industrial that has part number using 1.0V and 1.2V
I hope this answers your question.
