Receiver Status
The PCIe specification requires the PHY to encode the receiver status on a 3-bit
RxStatus[2:0] signal. The PIPE interface block receives status signals from the
transceiver channel PCS and PMA blocks and drives the status on the 3-bit output
signal (pipestatus[2:0]) to the FPGA fabric. The encoding of the status signals on the
pipestatus[2:0] port is compliant with the PCIe specification and is listed in
Table
Table 1–18. Encoding of the Status Signals on the pipestatus[2:0] Port for Arria II Devices
pipestatus[2:0]
Note to
(1) The PIPE interface follows the priority listed in
pipestatus[2:0] port. Two or more error conditions; for example, 8B/10B decode error (code group violation),
rate match FIFO overflow or underflow, or receiver disparity error, can occur simultaneously. When this happens,
PIPE drives 3'b100 on the pipestatus[2:0] signal.
