32.3.3. Error Conditions

The SG-DMA core has a configurable error width. Error signals are connected directly to the Avalon® -ST source or sink to which the SG-DMA core is connected.

The list below describes how the error signals in the SG-DMA core are implemented in the following configurations:

  • Memory-to-memory configuration

    No error signals are generated. The error field in the register and descriptor is hardcoded to 0.

  • Memory-to-stream configuration

    If you specified the usage of error bits in the core, the error bits are generated in the Avalon® -ST source interface. These error bits are hardcoded to 0 and generated in compliance with the Avalon® -ST agent interfaces.

  • Stream-to-memory configuration

    If you specified the usage of error bits in the core, error bits are generated in the Avalon® -ST sink interface. These error bits are passed from the Avalon® -ST sink interface and stored in the registers and descriptor.

    The table below lists the error signals when the core is operating in the memory-to-stream configuration and connected to the transmit FIFO interface of the Intel FPGA Triple-Speed Ethernet IP core.

    Table 356.   Avalon® -ST Transmit Error Types
    Signal Type Description
    TSE_transmit_error[0] Transmit Frame Error. Asserted to indicate that the transmitted frame should be viewed as invalid by the Ethernet MAC. The frame is then transferred onto the GMII interface with an error code during the frame transfer.

    The table below lists the error signals when the core is operating in the stream-to-memory configuration and connected to the transmit FIFO interface of the Triple-Speed Ethernet IP Core.

    Table 357.   Avalon® -ST Receive Error Types
    Signal Type Description
    TSE_receive_error[0] Receive Frame Error. This signal indicates that an error has occurred. It is the logical OR of receive errors 1 through 5.
    TSE_receive_error[1] Invalid Length Error. Asserted when the received frame has an invalid length as defined by the IEEE 802.3 standard.
    TSE_receive_error[2] CRC Error. Asserted when the frame has been received with a CRC-32 error.
    TSE_receive_error[3] Receive Frame Truncated. Asserted when the received frame has been truncated due to receive FIFO overflow.
    TSE_receive_error[4] Received Frame corrupted due to PHY error. (The PHY has asserted an error on the receive GMII interface.)
    TSE_receive_error[5] Collision Error. Asserted when the frame was received with a collision.

    Each streaming core has a different set of error codes. Refer to the respective user guides for the codes.
