MAX10 ADC doesn't start during power on

I'm using MAX10 ADC to measure on board voltages. The ADC IP operates normally when the design was programmed using JTAG USB Byte Blaster with SOF file. When same design is programmed using POF fil...

Do the power supplies you are using for the device meet the requirements for MAX 10? Refer to the "max 10 power management user guide (https://www.altera.com/literature/hb/max-10/ug_m10_pwr.pdf)".

If the ramp time, tRAMP, is not met, the MAX 10 device I/O pins and programming registers remain tristated, during which device configuration could fail.

It does not state exactly how this "could" fail. However, it may well be possible that partial configuration - of the logic - might occur and the ADC suffers. Subsequently programming it with a .sof, once the rails are all up and steady, could rectify this.

So, refer to figure 2-3 on page 2-6 and confirm your device rails comply.
