Why does my 4-channel variant with PTP enabled in the E-Tile Hard IP for Ethernet Intel® Stratix® 10 FPGA IP show as 6 channels when I open it in the Transceiver Toolkit?

Environment

  • Intel® Stratix® 10 MX FPGA
  • Intel® Stratix® 10 TX FPGA
  • Intel® Quartus® Prime Pro Edition
  • E-tile Hard IP for Ethernet Intel® FPGA IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 19.1 and earlier, the number of channels that are shown in Transceiver Toolkit for multi-channel variants of E-Tile Hard IP for Ethernet Intel® Stratix® 10 FPGA IP with PTP enabled is incorrect.

    Resolution

    In variants with PTP enabled, certain transceiver channels are reserved to support the PTP functionality. The channels reserved for PTP depend on the design’s physical placement.  These reserved channels should be ignored in Transceiver Toolkit. The PTP reserved channels in E-Tile are channels 4 and 5 for transceiver channels 0-3, channels 6 and 7 for transceiver channels 8-11, channels 16 and 17 for transceiver channels 12-15, and  channels 18 and 19 for transceiver channels 20-23.

     

    This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition software.
