3.3. SDM ECC and SmartVID Errors Signals Behavior

When the Intel® Agilex™ device detects an SDM ECC or SmartVID error, the generic_sdm_valid_out signal of the Advanced SEU Detection IP goes high for one clock cycle.

Always monitor the generic_sdm_valid_out signal. When the generic_sdm_valid_out signal goes high, retrieve the SDM ECC error message content from the generic_sdm_data_out signal of the Advanced SEU Detection IP.

For an example of analyzing ECC errors with Signal Tap after injecting the error and retrieving the error data, refer to the related information.
