Simulation Visualiation on Linux

[Altera_Forum]

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 Info: NativeLink has detected VHDL design -- VHDL simulation models will be used  ========= EDA Simulation Settings =====================  Sim Mode : RTL Family : cycloneii Quartus root : /home/eduardp/altera/13.0sp1/quartus/linux/ Quartus sim root : /home/eduardp/altera/13.0sp1/quartus/eda/sim_lib Simulation Tool : modelsim-altera Simulation Language : vhdl Version : 93 Simulation Mode : GUI Sim Output File :  Sim SDF file :  Sim dir : simulation/modelsim  =======================================================  Info: Starting NativeLink simulation with ModelSim-Altera software Sourced NativeLink script /home/eduardp/altera/13.0sp1/quartus/common/tcl/internal/nativelink/modelsim.tcl Warning: File register_run_msim_rtl_vhdl.do already exists - backing up current file as register_run_msim_rtl_vhdl.do.bak8 Info: Spawning ModelSim-Altera Simulation software    thanks in advance

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, GooGooCluster

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
