Description Due to a problem in the Intel® Quartus® Prime Standard Edition Software version 18.1 and earlier, you may see a warning message mentioned above while running a simulation for the Intel Arria® 10 EMIF example design in the Mentor Graphics ModelSim* simulator. Resolution To work around this problem, modify the Abstract PHY simulation model as described below.
