Description

Due to missing encrypted Verilog library files, you may see the below error message when simulating a VHDL version of the 10Gb Ethernet MAC MegaCore® function generated in Quartus® II software version 13.0 using ModelSim®. This happens only with VHDL and not Verilog when you have a single language license of ModelSim.
