In Quartus® Prime Pro Edition Software version 23.2 and earlier, when retrieving the Error Message Queue contents from Agilex™ 7 devices, you may observe that the reserved field located at sector address bit [11:8] displays a random value in the return message when a SmartVID error occurs.
The sector address bit [11:8] is intended to be reserved, and no value should be expected to be returned in that field.
Refer to the Agilex™ 7 SEU Mitigation User Guide for more details about SmartVID Error Message Bits.
This problem is fixed starting from Quartus® Prime Pro Edition Software version 23.3.
