Why do the Intel® Arria® 10 10GBASE-R Design Example User Guide and simulation test bench file show an incorrect Tx/Rx SC FIFO offset address ?

Environment

  • Intel® Quartus® Prime Pro Edition
  • Low Latency Ethernet 10G MAC Intel® FPGA IP
  • 1G 2.5G 5G 10G Multi-rate Ethernet PHY Intel® FPGA IP
  • 10GBASE-R PHY Intel® FPGA IP
  • 1G 10GbE and 10GBASE-KR PHY Intel® Arria® 10 FPGA IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem with the Intel® Arria® 10 10GBASE-R design example, the register map offset address for RX SC FIFO is 9400h and TX SC FIFO is 9600h.

    However, in the "Low Latency Ethernet 10G MAC Intel Arria 10 FPGA IP Design Example User Guide" (ug-20016), the offset address for RX SC FIFO is D400h and TX SC FIFO is D600h. 

     

     

    Resolution

    The 10GBASE-R design example's register map offset address for TX SC FIFO and RX SC FIFO will be amended to match with register map offset address in the ug-20016 design example user guide. 

    This problem will be fixed in a future version of the Intel® Quartus® Prime Software.
