After attempting correction of an error, the solution classifies the error. The classification result depends on the correction mode, error type, error location, and selected classification mode. The following table provides error classification latency for a configuration frame upset, assuming no throttling on the Monitor Interface.

Table 1. Error Classification Latency, No Throttling on Monitor Interface
Device Family Errors in Frame (Correctability) Classification Mode Error Classification Latency at ICAP_FMax (µs)
UltraScale Correctable Enabled 185 1
Uncorrectable Any 5 1
UltraScale+ Monolithic Correctable Enabled 154 2
Uncorrectable Any 5 2
UltraScale+ SSI Correctable Enabled 247 3
Uncorrectable Any 30 3
  1. Measured in hardware for XCKU040 device.
  2. Measured in hardware for XCVU3P device.
  3. Measured in hardware for XCVU9P device.

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