8.1. Error Insertion Test and Debugging

Error insertion allows you to test 25G Ethernet Intel FPGA IP core test error handling.

To use this feature, the Avalon® streaming TX client asserts l1_tx_error in the same cycle as l1_tx_endofpacket . The error appears as a 66-bit error block that consists of eight /E/ characters (EBLOCK_T) in the Ethernet frame. The 25G Ethernet Intel FPGA IP core overwrites Ethernet frame data with an EBLOCK_T error block when it transmits the Ethernet frame that corresponds to the packet EOP. The RX interface detects the frame corruption resulting in a CRC error output.
