3.2.4.19. Error Conditions on Rx Datapath
The Rx MAC indicates error conditions by asserting avl_st_rx_err. The following
error conditions are defined:
■

■
■
■
If your design includes a FIFO in store and forward mode, setting the
FIFO_ERR_DIS bit to 1 in the command_config register discards the errored
packets in the FIFO.
The 10-Gbps Ethernet IP core ECC feature implements single-bit error correction and
double-bit error detection (SECDED).
The ALTECC megafunction performs the ECC encoding and decoding for this IP
core. You can find additional information about this megafunction in the ALTECC
(Error Correction Code: Encoder/Decoder section of the
