Signal Name

rx_rmfifodatainserted[-1:0]

Output

When asserted, indicates that the RX

rate match block inserted an ||R||

column.

rx_rmfifodatadeleted[-1:0]

Output

When asserted, indicates that the RX

rate match block deleted an ||R||

column.

rx_rlv[ -1:0]

Output

When asserted, indicates a run length

violation. Asserted if the number of

consecutive 1s or 0s exceeds the

number specified in the MegaWizard

Plug-In Manager.

rx_recovered_clk[-1:0]

Output

This is the RX clock which is

recovered from the received data

stream.

rx_byteordflag[-1:0]

Output

This status flag is asserted high the

received data is aligned to the byte

order pattern that you specify.

Optional Reset Control and Status Interface

This topic describes the signals in the optional reset control and status interface. These signals are

available if you do not enable the embedded reset controller.

Description

pll_powerdown

Input

When asserted, resets the TX PLL.

tx_digitalreset[-1:0]

Input

When asserted, reset all blocks in the TX PCS. If

your design includes bonded TX PCS channels,

refer to Timing Constraints for Reset Signals when

Using Bonded PCS Channels for a SDC constraint

you must include in your design.

tx_analogreset[-1:0]

Input

When asserted, resets all blocks in the TX PMA.
Note: For Arria V devices, while compiling a

multi-channel transceiver design, you

will see a compile warning (12020) in

Quartus II software related to the signal

width of tx_analogreset. You can safely

ignore this warning. Also, per-channel

TX analog reset is not supported in

Quartus II software. Channel 0 TX

analog resets all the transceiver

channels.
