After detecting an error, the solution attempts correction. Errors are correctable depending on the selected correction mode and error type. The following table provides error correction latency for a configuration frame upset, assuming no throttling on the Monitor Interface.
| Device | Correction Mode | Correctability | Error Correction Latency at ICAP_FMax (µs) |
|---|---|---|---|
| UltraScale | Repair | Correctable 1 | 41 2 |
| Uncorrectable | 21 2 | ||
| Any | CRC-only (Uncorrectable) | 9 | |
| UltraScale+ Monolithic | Repair | Correctable 1 | 44 3 |
| Uncorrectable | 22 3 | ||
| Any | CRC-only (Uncorrectable) | 9 | |
| UltraScale+ SSI | Repair | Correctable 1 | 99 4 |
| Uncorrectable | 38 4 | ||
| Any | CRC-only (Uncorrectable) | 15 | |

The error correction latency at the actual frequency of operation can be estimated using data from the previous table and the following equation.
