Due to the Intel® Quartus® Prime Pro Edition Software version 19.3 and earlier, the pin-out file report with Intel® Arria® 10 devices is differnet from the Intel® Arria® 10 pin-out datasheet ver1.6 .
For example, if you look at page 13 of the Intel® Arria® 10 pin-out datasheet ver1.6, the 10AX115H3F34I2LG device AP2 pin and B1 pins are RREF_BR/RREF_TR while these are reported as GND in the Intel® Quartus® Prime Pro Edition Software version 19.3 and earlier.
The Intel® Arria® 10 FPGA pin-out datasheet ver1.6 is correct.
The Intel® Quartus® Prime Pro Edition Software is fixed in version 20.3.
