Failed to transfer to modelsim

[Altera_Forum]

In the .mdl file,when I used the Testbench model to run modelsim, errers were found in modelsim:  

 # Reading D:/altera/71/modelsim_ae/tcl/vsim/pref.tcl  # source tb_mymodel.tcl  # Loading project DspBuilder # vsim -quiet -t {1 ps} work.tb_mymodel_GN2124  # ** Error: Failure to obtain a VHDL simulation ******. # Error loading design # Unrecognized dataset prefix: sim  what's the matter?  Thanks!

Are you using the same version number for QuartusII and Modelsim?

Was the error line you stated 

 # ** Error: Failure to obtain a VHDL simulation   actually   # ** Error: Failure to obtain a VHDL simulation license?  Looks a bit similar too the normal modelsim failure if your license file is not setup properly.  Have a look here  http://www.altera.com/support/licensing/lic-index.html  For info on how to setup the license files and environment variables

I am sorry. Yes，the error is # ** Error: Failure to obtain a VHDL simulation license.  

  I used the same version number for QuartusII and Modelsim, and its license files and environment variables should be right , I used it before. I will check it too.

Thanks，I solved the problem. My license was incomplete, and I have updated it. Now it's OK.
