You cannot turn on this parameter while using the Basic/Custom w/Rate Match (Standard PCS) specified for Transceiver configuration rules.
Table 25.  Standard PCS FIFO Parameters
Parameter Range Description
TX FIFO mode

low_latency

register_fifo

fast_register

Specifies the Standard PCS TX FIFO mode. The following modes are available:
  • low_latency: This mode adds 2-3 cycles of latency to the TX datapath.
  • register_fifo: In this mode the FIFO is replaced by registers to reduce the latency through the PCS. Use this mode for protocols that require deterministic latency, such as CPRI.
  • fast_register: This mode allows a higher maximum frequency (fMAX) between the FPGA fabric and the TX PCS at the expense of higher latency.
RX FIFO mode

low_latency

register_fifo

The following modes are available:
  • low_latency: This mode adds 2-3 cycles of latency to the RX datapath.
  • register_fifo: In this mode the FIFO is replaced by registers to reduce the latency through the PCS. Use this mode for protocols that require deterministic latency, such as CPRI or 1588.

RX word aligner mode

bitslip

manual (PLD controlled)

synchronous state machine

deterministic latency

Specifies the RX word aligner mode for the Standard PCS. The word aligned width depends on the PCS and PMA width, and whether or not 8B/10B is enabled.

Refer to "Word Aligner" for more information.

RX word aligner pattern length

7, 8, 10, 16, 20, 32, 40

Specifies the length of the pattern the word aligner uses for alignment.

Refer to "RX Word Aligner Pattern Length" table in "Word Aligner". It shows the possible values of "Rx Word Aligner Pattern Length" in all available word aligner modes.

RX word aligner pattern (hex) User-specified Specifies the word alignment pattern in hex.
Number of word alignment patterns to achieve sync 0-255 Specifies the number of valid word alignment patterns that must be received before the word aligner achieves synchronization lock. The default is 3.
Number of invalid words to lose sync 0-63 Specifies the number of invalid data codes or disparity errors that must be received before the word aligner loses synchronization. The default is 3.
Number of valid data words to decrement error count 0-255 Specifies the number of valid data codes that must be received to decrement the error counter. If the word aligner receives enough valid data codes to decrement the error count to 0, the word aligner returns to synchronization lock.
Enable fast sync status reporting for deterministic Latency SM On / Off When enabled, the rx_syncstatus asserts high immediately after the deserializer has completed slipping the bits to achieve word alignment. When it is not selected, rx_syncstatus asserts after the cycle slip operation is complete and the word alignment pattern is detected by the PCS (i.e. rx_patterndetect is asserted). This parameter is only applicable when the selected protocol is CPRI (Auto).
Enable rx_std_wa_patternalign port On / Off Enables the rx_std_wa_patternalign port. When the word aligner is configured in manual mode and when this signal is enabled, the word aligner aligns to next incoming word alignment pattern.

Table 30.  Bit Reversal and Polarity Inversion
Parameter Range Description
Enable TX bit reversal On / Off When you turn on this option, the 8B/10B Encoder reverses TX parallel data before transmitting it to the PMA for serialization. The transmitted TX data bit order is reversed. The normal order is LSB to MSB. The reverse order is MSB to LSB. During the operation of the circuit, this setting can be changed through dynamic reconfiguration.
Enable TX byte reversal On / Off When you turn on this option, the 8B/10B Encoder reverses the byte order before transmitting data. This function allows you to reverse the order of bytes that were erroneously swapped. The PCS can swap the ordering of either one of the 8- or 10-bit words, when the PCS/PMA interface width is 16 or 20 bits. This option is not valid under certain Transceiver configuration rules.
Enable TX polarity inversion On / Off When you turn on this option, the tx_std_polinv port controls polarity inversion of TX parallel data to the PMA. When you turn on this parameter, you also need to turn on the Enable tx_polinv port.
Enable tx_polinv port On / Off When you turn on this option, the tx_polinv input control port is enabled. You can use this control port to swap the positive and negative signals of a serial differential link, if they were erroneously swapped during board layout.
Enable RX bit reversal On / Off When you turn on this option, the word aligner reverses RX parallel data. The received RX data bit order is reversed. The normal order is LSB to MSB. The reverse order is MSB to LSB. This setting can be changed through dynamic reconfiguration.

When you enable Enable RX bit reversal, you must also enable Enable rx_std_bitrev_ena port.

Enable rx_std_bitrev_ena port On / Off When you turn on this option and assert the rx_std_bitrev_ena control port, the RX data order is reversed. The normal order is LSB to MSB. The reverse order is MSB to LSB.
Enable RX byte reversal On / Off When you turn on this option, the word aligner reverses the byte order, before storing the data in the RX FIFO. This function allows you to reverse the order of bytes that are erroneously swapped. The PCS can swap the ordering of either one of the 8- or 10-bit words, when the PCS / PMA interface width is 16 or 20 bits. This option is not valid under certain Transceiver configuration rules.

When you enable Enable RX byte reversal, you must also select the Enable rx_std_byterev_ena port.

Enable rx_std_byterev_ena port On / Off When you turn on this option and assert the rx_std_byterev_ena input control port, the order of the individual 8‑ or 10‑bit words received from the PMA is swapped.
Enable RX polarity inversion On / Off

When you turn on this option, the rx_std_polinv port inverts the polarity of RX parallel data. When you turn on this parameter, you also need to enable Enable rx_polinv port.

Enable rx_polinv port On / Off When you turn on this option, the rx_polinv input is enabled. You can use this control port to swap the positive and negative signals of a serial differential link if they were erroneously swapped during board layout.
Enable rx_std_signaldetect port On / Off When you turn on this option, the optional rx_std_signaldetect output port is enabled. This signal is required for the PCI Express protocol. If enabled, the signal threshold detection circuitry senses whether the signal level present at the RX input buffer is above the signal detect threshold voltage that you specified. You can specify the signal detect threshold using a Quartus Prime Assignment Editor or by modifying the Quartus Settings File (.qsf)
Table 31.  PCIe Ports
Parameter Range Description
Enable PCIe dynamic datarate switch ports On / Off When you turn on this option, the pipe_rate, pipe_sw, and pipe_sw_done ports are enabled. You should connect these ports to the PLL IP core instance in multi-lane PCIe Gen2 configurations. The pipe_sw and pipe_sw_done ports are only available for multi-lane bonded configurations.
Enable PCIe pipe_hclk_in and pipe_hclk_out ports On / Off When you turn on this option, the pipe_hclk_in, and pipe_hclk_out ports are enabled. These ports must be connected to the PLL IP core instance for the PCI Express configurations.
Enable PCIe electrical idle control and status ports On / Off When you turn on this option, the pipe_rx_eidleinfersel and pipe_rx_elecidle ports are enabled. These ports are used for PCI Express configurations.
Enable PCIe pipe_rx_polarity port On / Off When you turn on this option, the pipe_rx_polarity input control port is enabled. You can use this option to control channel signal polarity for PCI Express configurations. When the Standard PCS is configured for PCIe, the assertion of this signal inverts the RX bit polarity. For other Transceiver configuration rules the optional rx_polinv port inverts the polarity of the RX bit stream.
