Due to a problem in the Intel® Quartus® Prime Pro software version 19.4, the example design testbench for E-Tile Hard IP for Ethernet Intel® Stratix® 10 FPGA IP variant with a single channel of 10GBASE-KR selected will not complete when using Ncsim® or Xcellium®.
To work around this issue, increase the number of channels in your 10GBASE-KR variant to greater than ‘1’ when simulating the example design with Ncsim or Xcellium.
This problem is fixed starting with the Intel® Quartus® Prime Pro software version 20.1.
