3.6.3.10.4. Error Injection

To support testing of error handling software the Cortex* -A55 core can fake errors in the error detection logic.
The following table describes all the possible types of error that the core can encounter and therefore fake.
Table 52.  Errors Injected in the Cortex* -A55 Core
Error Type Description
Corrected errors A corrected error is generated for a single-bit ECC error on L1 data cache access.
Deferred errors A deferred error is generated for a double-bit ECC error on eviction of a cache line from the L1 to the L2, or as a result of a snoop on the L1.
Uncontainable errors An uncontainable error is generated for a double-bit ECC error on the L1 tag RAM following an eviction.
Latent error A UEO is generated as a double-bit ECC error on an L1 data read.
