How deal with this error when simulating PCIe HIP?

Hi dears,

I'm simulating the pcie hip according the user guide. I would get below errors when i execute the command "ld_debug" in Modelsim's transcrip.

# Model Technology ModelSim SE vlog 6.5a Compiler 2009.03 Mar 27 2009# ** Error: d:/altera/12.1sp1/quartus/eda/sim_lib/mentor/stratixv_atoms_ncrypt.v(27): Missing '`pragma protect ????_block encoding'# ** Error: d:/altera/12.1sp1/quartus/eda/sim_lib/mentor/stratixv_atoms_ncrypt.v(28): Pragma protect keyword expected# ** Error: d:/altera/12.1sp1/quartus/eda/sim_lib/mentor/stratixv_atoms_ncrypt.v(31): A key_method must be specified.# ** Error: d:/altera/12.1sp1/quartus/eda/sim_lib/mentor/stratixv_atoms_ncrypt.v(31): near ",": syntax error, unexpected ',', expecting "class"

As above informations, you can know my Modelsim's version, and my QII is 12.1.
