2.2. Error Message Queue

When it detects an SEU error, the Intel® Agilex™ device stores the error information in the error message queue. Each error message records the sector address, type, and location of the error. The error message queue is capable of storing a maximum of eight different messages. A warning message appears if the error message queue has more than eight different messages. Click Read EMR to display and clear the error message queue.

The SEU_ERROR signal goes high whenever the error message queue contains one or more error messages. The signal stays high if there is an error message in the queue. The SEU_ERROR signal goes low only when the SEU error message queue is empty—after you read out all the error messages. You must set the SEU_ERROR pin function to observe the SEU_ERROR pin behavior.

To retrieve the error message queue contents, use these tools:

  • Intel® Quartus® Prime Fault Injection Debugger
  • Advanced SEU Detection Intel® FPGA IP

32 31:29 Error type:
  • 001—single bit error
  • 010—double adjacent bit error
  • 011—uncorrectable multiple bits error
28 Correction Status:
  • 0—not corrected
  • 1—corrected
27:24 Reserved
23:12 Bit position within the frame
11:0 Combination of row and frame index
Related Information
1 For single bit error with internal scrubbing, the error location provides the error bit position. For multiple bit errors or single bit error without internal scrubbing, bit [23:0] returns 0.
