LM_LICENSE_FILE or MGLS_LICENSE_FILE for RTL simulation

Hi,

Im running quartus lite 17.1.0 on ubuntu 17.04. When I try to run RTL simulation I get an error output about LM_LICENSE_FILE or MGLS_LICENSE_FILE. The path to /modelsim_ase/linuxaloem is set correct.

It looks like several users have the same problem, but no solution.

What can I do, to continue my project?

    Hi

    1.Is ModelSim-Altera Licensed ?

    2.Recheck the License path and Environment variable.

    3.Or try with Modelsim Altera starter edition which is free.

    Best Regards,

    When you install the tools under Linux, you need to specify the License file location . This is done by specifying the following variables:

    LM_LICENSE_FILE --> path to license file for all tools which use FLEXLM licensing

    MGLS_LICENSE_FILE --> specific license variable for Mentor Graphics tools

    You will need to edit the .bashrc or .cshrc file in your login and add the following variables there

    export LM_LICENSE_FILE = <path to your license.dat file>

    export MGLS_LICENSE_FILE = <path to your license.dat file>

    export PATH = $PATH:<path to modelsim executable>:<path to quartus tool executable>

    Save and close the .bashrc/.cshrc file. Start a new terminal and you can invoke the tools .

    I installed Quartus 13.1 Free Edition and the Modelsim-Altera works fine in Windows 10. In Ubuntu however, the application cannot find the license file and I need to point to it as you said. According to this guide: http://cseweb.ucsd.edu/classes/fa10/cse140l/lab/docs/quartus_install.pdf The license.dat file should be somewhere in the root folder but I can't find it there too. Any idea where the license.dat file could be located in a Linux installation? I have tried performing "ls --recursive | grep license.dat" in the quartus installation folder to no avail too.
