2.6.1. Fault Injection Debugger

Using the Fault Injection Debugger, you can inject random CRAM bit flips into the Intel Agilex® 7 FPGA during system operation. With these simulated SEU strikes, you can test, debug, and refine your design's SEU detection and recovery sequence.

You can only perform error injection when LUTRAM is configured as LUT and it discards when the LUTRAM is configured as a RAM. The Fault Injection Debugger tool prompts a warning message to indicate the error injection occurs at LUTRAM if you turn on the LUTRAM Checking option. Intel recommends adding .smh for better accuracy of LUTRAM checking.

Features of the Fault Injection Debugger:

  • Inject single-bit error to a random location or a specified region.
  • Report error information by reading the error message queue.
Note: To use the Fault Injection Debugger, you require a licensed Intel® Quartus® Prime software with the "fault_injection_debugger_tool" feature in the license. To check if you have the feature in your license, from the Intel® Quartus® Prime software menu, select Assignment > Device. Click Device and Pin Options and then navigate to Error Detection CRC. If you can turn on Allow SEU fault injection, then you have the necessary license to use the Fault Injection Debugger tool.
