Why is the package temperature higher than the die temperature on Intel® FPGA Programmable Acceleration Card N3000?

Description

When reading temperature by fpgainfo temp command on Intel® FPGA Programmable Acceleration Card N3000, the package temperature may be higher than the die temperature.
It's expected behavior.

Resolution

The package temperature and die temperature are both temperatures of the Intel® Arria® 10 FPGA.

The die temperature is the temperature value read by the on-board sensor component via the TEMPDIODE pins of Intel® Arria® 10 FPGA.
The accuracy is +/-1C.

The package temperature is the temperature value read by the internal TSD (Temperature Sensing Diode) of Intel® Arria® 10 FPGA.
The accuracy is +/- 5C.
