The Intel® Stratix® 10 Low Latency 10G Ethernet MAC Example Designs will fail to simulate correctly in either NCSim or Xcelium for the configurations below:
1/2.5/10G with 1588
No work around for NCSim or Xcelium is available.
Please use VCS or ModelSim to simulate this IP core with software version v17.1 or v18.0
The simulation problem when using NCSim or Xcelium is scheduled to be fixed in a future version of Intel Quartus® Prime Pro software.
