Description | Fault Inject ECC |
This register is used to inject errors in the generated ECC written to the block RAM and can be used to test the error correction and error signalling. The bits set in the register toggle the corresponding ECC bits of the next data written to block RAM. After the fault has been injected, the Fault Injection ECC Register is cleared automatically. IMPORTANT: Injecting faults should be performed in a critical region in software, that is, writing to this register and the subsequent write to LMB BRAM must not be interrupted.
