Error: low_latency_40g_eth_top.alt_e40_0: 40GBASE No FLOW CONTROL, PRIORITY QUEUE should set as 1

Environment

  • Intel® Stratix® 10 FPGAs and SoC FPGAs
  • Intel® Quartus® Prime Pro Edition
  • Low Latency 40G 100G Ethernet
  • Low Latency 40G Ethernet Intel® FPGA IP for Arria® 10 and Stratix® V
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    You may see this error in the Intel® Quartus® Prime Pro software version 18.1 when upgrading the Low Latency 40G IP from Intel® Quartus® Prime Pro software version 18.0 using a priority queue of 8 with flow control.

    Resolution

    To work around this problem you need to change the priority queue to 1 without flow control in the Low Latency 40G IP since a priority queue of 8 with flow control is not supported.
