@rammi The VCCINT and VCCAUX are also out of spec. Can you share your Sysmon Interface Schematic showing AVDD, VREFP, VREPN, and AVSS connections.

Can you try using Chipscope and report back on what you are getting?

@gnarahar The issue was resolved. This issue due to VREFP(ADC reference voltage)  regulator misbehavior. Now its reading proper temperature.

Thanks @gnarahar
