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.
# ** Error: Failure to obtain a Verilog simulation license. Unable to checkout any of these license features: msimhdlmix; qhsimvl; or msimhdlsim# ** Error: (vsim-3039) ./..//AlteraTenGigMac.vhd(4743): Instantiation of 'altera_avalon_st_pipeline_stage' failed.
