5.5. Error Detection, Reporting, and Recovering Mechanism

Table 23.  Error Conditions, Core Behavior, Reporting, and Recovering MechanismThis table lists the error conditions that the core detect, their behavior in response to each condition, and available reporting mechanisms.

Condition

IP Behavior

Reporting Mechanism Recovering Mechanism

Source Core

Burst gap error

The source detects the burst gap between two consecutive bursts does not match Required idle cycles between bursts parameter setting.

The source core asserts the error flag for one clock cycle.

  • tx_burst_gap_err of TX Error Status register set to 1 (only for Intel® Stratix® 10 devices).
  • error/error_tx[3] signal asserted.
  • err_interrupt/err_interrupt_tx signal asserted (only available when tx_burst_gap_err_en of TX Error Interrupt Enable register is set to 1 (only for Intel® Stratix® 10 devices).
Make sure the burst gap of the incoming packet is matching the Required idle cycles between burstsparameter.

Rate adaptation FIFO buffer overflow in source interface.

There is an overflow on the rate adaptation FIFO buffer in the source interface. The core behavior depends on the operation mode:

  • Continuous mode—error is flagged once an overflow is detected.
  • Burst mode—error is flagged only when an overflow occurs during burst data transfer across the user interface.

The source core asserts the error flag when the FIFO is in overflow condition.

  • adapt_fifo_overflow of TX Error Status register set to 1 (only for Intel® Stratix® 10 devices).
  • error/error_tx[0] signal asserted.
  • err_interrupt/err_interrupt_tx signal asserted (only available when adapt_fifo_overflow_en of TX Error Interrupt Enable register is set to 1 (only for Intel® Stratix® 10 devices).
  • Assert phy_mgmt_clk_reset to reset the IP.
  • Send empty cycle to prevent FIFO overflow.

ECC fatal error.

The source core asserts the error flag for one clock cycle when a double bit error is detected.

  • adapt_fifo_overflow of TX Error Status register set to 1 (only for Intel® Stratix® 10 devices).
  • error/error_tx[0] signal asserted.
  • err_interrupt/err_interrupt_tx signal asserted (only available when ecc_err_fatal_en of TX Error Interrupt Enable register is set to 1 (only for Intel® Stratix® 10 devices).
Assert phy_mgmt_clk_reset signal to reset the IP.

ECC corrected error.

The source core asserts the error flag for one clock cycle when a single bit error is detected and corrected.

  • ecc_err_corrected of TX Error Status register set to 1 (only for Intel® Stratix® 10 devices).
  • error/error_tx[1] signal asserted.
  • err_interrupt/err_interrupt_tx signal asserted (only available when ecc_err_corrected_en of TX Error Interrupt Enable register is set to 1 (only for Intel® Stratix® 10 devices).

  • err_interrupt/err_interrupt_tx signal asserted (only available when tx_sync_donelost_en of TX Error Interrupt Enable register is set to 1 (only for Intel® Stratix® 10 devices).

The source core automatically re-initialize the link when this error occurs.

Optionally, you can assert phy_mgmt_clk_reset to reset the IP.

Sink Core

RX data error

When the sink interface receives data but ready_rx signal is de-asserted.

  • rx_data_err of RX Error Status register set to 1 (only for Intel® Stratix® 10 devices).
  • err_interrupt/err_interrupt_rx signal asserted (only available when rx_data_err_int_en of RX Error Interrupt Enable register is set to 1 (only for Intel® Stratix® 10 devices).

RX PCS Error

One or more errors have occurred in a given meta-frame, as determined by Native PHY PCS logic (in Interlaken mode).

These errors could be triggered much later (with respect to the user packets received earlier) at the receiving link.

Note: If data integrity is critical, additional error checksum may be included in the user logic as part of data payload so that the downstream user logic can determine the data integrity at packet level.
