7.2.8. Checking FEC Statistics
You can view the FEC statistics when you enable the RS-FEC option in the IP parameter editor. To view the FEC statistics in the Transceiver Toolkit, navigate to the Toolkit Parameters tab and check the CWBIN Counter pane.
- Corrected Codewords A/B indicates the codewords that are corrected by the FEC logic.
- Uncorrected A/B indicates the codewords that are not corrected by the FEC logic.
- Total Error free Codewords A/B indicates the FEC codewords received without any errors.
- hard_cwbin1_A/B indicates the FEC codewords received with 1 error.
- hard_cwbin2_A/B indicates the FEC codewords received with 2 errors.
- hard_cwbin3_A/B indicates the FEC codewords received with 3 errors and so on up to hard_cwbin15_A/B for FEC codewords received with 15 errors.
For 8 and 16 lane designs, two FEC codewords, A and B, are received in parallel. The counting of codewords is done separately for A and B codewords.
For 8 lane designs: Statistics for A codewords are reported in the first lane entry in the even-numbered FEC core, and statistics for the B codewords are reported in the first lane entry in the odd-numbered FEC core.
For 16 lane designs: Statistics for A codewords are reported in the first lane entry in FEC core 0 and statistics for the B codewords are reported in the first lane entry of FEC core 2.
