Simulation Visualiation on Linux

Question

I am using Ubuntu, when I try to use ModelSim-Altera tu run a RTL simulation, I get the messages:

Info (22036): Successfully launched NativeLink simulation (quartus_sh -t "/home/eduardp/altera/13.0sp1/quartus/common/tcl/internal/nativelink/qnativesim.tcl" --rtl_sim "register" "register")

Info (22036): For messages from NativeLink execution see the NativeLink log file /home/eduardp/ProjetosAltera/TutorialVHDL/register1bit/register_nativelink_simulation.rpt

But nothing shows up. ModelSim seems to work fine when I open it using ./vsim.

Someone else asked this at http://www.alteraforum.com/forum/archive/index.php/t-48630.html , but it's not solved and my problem seems not to be ModelSim installation nor my OS.

This is the file register_nativelink_simulation.rpt :

Info: Start Nativelink Simulation process

Hi,

I'm using Fedora and had the same problem. As it turned out, Quartus starts ModelSim, but ModelSim itself cannot run due to some problems; however, Quartus only saw that the ModelSim process started, and reported that everything was successful.

What helped me are these two articles: https://wiki.archlinux.org/index.php/altera_design_software#modelsim-altera_edition (https://wiki.archlinux.org/index.php/altera_design_software#modelsim-altera_edition) and http://mattaw.blogspot.de/2014/05/making-modelsim-altera-starter-edition.html (http://mattaw.blogspot.de/2014/05/making-modelsim-altera-starter-edition.html).

In a nutshell:

manually execute ModelSim from the shell to see what it tells you; the executable is /installation_path/modelsim_a
you probably need all sorts of packets to be installed manually
you probably have to modify the ModelSim startup script (the same file as in my last bullet point), to be compatible with your Linux version
you probably have to install an old version of the freetype library, because the latest and greatest that is installed with modern Linux distros is incompatible with ModelSim

I have to admit that I never use NativeLink, as manually writing scripts for ModelSim is way more conventient, but I double-checked that on my system invoking ModelSim through NativeLink from Quartus works.

Best regards,

Thanks for your answer!!

I followed the steps in both links, I had mad the freetype thing before, I think what really made it work was setting modelsim_ase/bin instead of modelsim_ase/linuxaloem as the path to modelsim-altera
