Hi everyone. Today, I will share you how to install ModelSim and fix some error in Linux. Modelsim is a software use to compile, simulation HDL (VHDL, Verilog).

Install

• Firstly, I need to download file ModelSimSetup-16.1.0.196-linux.run in here or newest version in official website of Altera in here.
• Go to the download location of the .run file and type:

  chmod +x ModelSimSetup-16.1.0.196.run
  

• Use the command:

  ./ModelSimSetup-13.1.0.162.run install Modelsim
  

• Change your directory to “Location_where_you_installed_Modelsim‘/altera/13.1/modelsim_ase/linuxaloem”
• Type

  ./vsim
  

If you have error, I don’t worry. I will help you now:

Error

./vsim: No such file or directory

• I investigated further on internet and found that I require 386-32 bit libraries for Ubuntu since the Modelsim seems to be 32-bit. So I took the followings steps on the Linux command prompt:

  sudo dpkg --add-architecture i386 
  sudo apt-get update 
  sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 
  sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 
  

  libXft.so.2: cannot open shared object file

• So I took the following steps:

    sudo  apt-get install libxft2 libxft2:i386 lib32ncurses5
  

  libXext.so.6: cannot open shared object file. libXext.so.6 not found

• Continues following steps:

     sudo apt install libxext6
     sudo apt install libxext6:i386
  

Finally, this solved the problem. I was able to invoke ModelSim using ./vsim command. Maybe the font size in text editor of ModelSim is very small. You can write source code by vim or gedit, then compile and simulation by ModelSim. 😀 If you have any error, you can’t following this website. Source: dtypist, theeureka, matthew
