A typical error is libXt.so.6: cannot open shared object file or error while loading shared libraries: libXft.so.2 . QuestaSim requires several 32-bit packages even on a 64-bit system. These include libXft , libncurses , and libstdc++ . The solution for a portable setup is to install them on the host OS using its native package manager, as explained in the launch script idea earlier.
Download the full Linux installer from the Siemens Support Center.
You cannot download an official single-file portable version of QuestaSim. Siemens provides standard Linux installation packages. However, you can make your own portable version easily. Follow these simple steps. 1. Download the Linux Files
touch ~/portable_eda/questasim_portable.sh chmod +x ~/portable_eda/questasim_portable.sh Use code with caution.
#!/bin/bash # Get the absolute path of the script directory SCRIPT_DIR="$( cd "$( dirname "$BASH_SOURCE[0]" )" && pwd )" # Set QuestaSim Environment Variables export MGC_HOME="$SCRIPT_DIR" export PATH="$SCRIPT_DIR/bin:$PATH" # Optional: Point to your license file or license server # export LM_LICENSE_FILE=1717@your_license_server echo "QuestaSim Portable Environment Initialized." echo "Launch the GUI by typing: vsim" $SHELL Use code with caution. Make the script executable: chmod +x launch_questa.sh Use code with caution. Handling Linux Dependency Issues download questasim for linux portable
Instead of modifying the target machine's .bashrc or system variables (which defeats the purpose of portability), create a run.sh script in the root of your USB drive.
To achieve a "portable" setup, you need to simulate a full installation in a specific directory.
Install Mentor Graphics Questasim 2021.2 on Ubuntu 24.04 LTS
: Edit the .bashrc file in your home directory. You can use any text editor: A typical error is libXt
Ensure you used source questa_env.sh rather than executing it directly with ./questa_env.sh . Sourcing executes the script parameters within the current shell context. Error: libXft.so.2: cannot open shared object file
You're looking for a way to download and use QuestaSim for Linux in a portable manner.
If you want to tailor this setup for your specific workstation, let me know: Your targeted (Ubuntu, RHEL, etc.) The specific QuestaSim version you are trying to package Your licensing model (local node-locked or remote server)
chmod +x QuestaSetup-linux.run ./QuestaSetup-linux.run --mode folder --prefix ~/eda/questasim Use code with caution. Copied to clipboard 🚀 Step 3: Making it "Portable" via Scripts The solution for a portable setup is to
export QUESTA_HOME="$SCRIPT_DIR/questasim" # Adjust path as needed export PATH="$QUESTA_HOME/bin:$PATH" export PATH="$QUESTA_HOME/linux_x86_64:$PATH"
#!/bin/bash # Determine the absolute directory where this script resides SCRIPT_DIR="$( cd "$( dirname "$BASH_SOURCE[0]" )" && pwd )" # Define internal paths export QUESTA_HOME="$SCRIPT_DIR/questasim" export PATH="$QUESTA_HOME/bin:$PATH" # Isolate internal libraries if necessary export LD_LIBRARY_PATH="$SCRIPT_DIR/libs:$QUESTA_HOME/lib:$LD_LIBRARY_PATH" # Configure the license location (Change to your actual server port and host) export MGLS_LICENSE_FILE="1717@your-license-server-ip" echo "=====================================================" echo " Portable QuestaSim Environment Initialized " echo " QUESTA_HOME: $QUESTA_HOME " echo "=====================================================" # Launch the simulator GUI, forwarding any arguments passed to the script exec vsim "$@" Use code with caution. Make the script executable: chmod +x launch_questa.sh Use code with caution.
Installing 32-bit compatibility libraries (often required even on 64-bit systems) and ensuring the shell (typically ) is correctly configured. The Environment: Defining the directory and setting the LM_LICENSE_FILE
If vsim fails to start with errors about .so files, it's almost always a missing 32-bit library. Re-check the dependencies.
When running the installer, do not install to /opt/mgc . Instead, point the installation directory to a path within your home folder or a dedicated tools partition, such as: ~/tools/questasim_2023.2 B. Bundling Dependencies
