Is the transceiver Standard PCS 8B/10B decoder compliant to the Fibre Channel specification in Arria 10, Cyclone® 10 GX, and Stratix® 10 L-Tile and H-Tile devices?

Environment

    Intel® Quartus® Prime Pro Edition
    Transceiver Native PHY Intel® Arria® 10 Cyclone® 10 FPGA IP
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

No, the transceiver Standard PCS 8B/10B decoder is not fully compliant with the Fibre Channel specification in Arria 10, Cyclone® 10 GX, and Stratix® 10 L-Tile and H-Tile devices.

The Fibre Channel protocol requirements for "Detection of Invalid transmission Word" for certain data rates state that Ordered Sets received with incorrect beginning running disparity be flagged as an error. The Arria 10, Cyclone® 10 GX, and Stratix® 10 L-Tile and H-Tile device 8B/10B decoder determines running disparity on a character-by-character basis and not Ordered Sets.

Due to this non-compliance, you may be unable to use the transceiver Standard PCS 8B/10B decoder.

Resolution

To work around this problem you can implement Fibre Channel compliant 8B/10B decoding in the FPGA core.
