Name | Avalon Streaming Signal Type | I/O | Description |
---|---|---|---|
Avalon Streaming Signals | |||
data_tx_valid_n | valid | I | Transmit data valid. Assert this signal to indicate that the data on the following signals are valid: data_tx_data_n, data_tx_sop_n, data_tx_eop_n, and data_tx_error_n. |
data_tx_data_n[7:0] | data | I | Transmit data. |
data_tx_sop_n | startofpacket | I | Transmit start of packet. Assert this signal when the first byte in the frame is driven on data_tx_data_n. |
data_tx_eop_n | endofpacket | I | Transmit end of packet. Assert this signal when the last byte in the frame (the last byte of the FCS field) is driven on data_tx_data_n. |
data_tx_error_n[4:0] | error | I | Transmit frame error. Assert this signal with the final byte in the frame to indicate that the transmit frame is invalid. The MAC function then forwards the frame to the GMII with error. |
data_tx_ready_n | ready | O | MAC ready. When asserted, this signal indicates that the MAC function is ready to accept data from the user application. |
Component-Specific Signal | |||
tx_crc_fwd_n | — | I | Transmit CRC insertion. Assert this active-low signal when data_tx_eop_n is asserted for the MAC function to compute the CRC and insert it into the frame. Otherwise, the user application is expected to provide the CRC. |
