Is there a known problem with VREF pin reporting in the Intel® Quartus® Prime Pro Edition Software version 21.4 when using Intel® Stratix® 10 devices? - Is there a known problem with VREF pin reporting in the Intel® Quartus® Prime Pro Edition Software version 21.4 when using Intel® Stratix® 10 devices? Description Yes, due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.4, the " All Package Pins " report will show incorrect VREF requirements for Intel® Stratix® 10 devices when no GPIOs in the respective I/O bank use a voltage standard that requires a VREF. Resolution To work around this, compare the Pin Planner settings for the respective bank with the Intel Stratix 10 Device Datasheet I/O Standard Specifications VREF requirement. If all your pins in the bank do not require a VREF, then connecting the VREF pin to GND is safe. This problem will be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
