The two most critical variables are:
Make it executable: chmod +x setup_questa.sh
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)
Ensure that your launch_questa.sh script points to the correct IP address or license file path. If you are using a network license, ensure that firewall ports (typically 1717 or 27000) are open between your host machine and the license server. 3. Font Rendering Issues in the GUI download questasim for linux portable
If you prefer to run command-line compilation ( vlog , vcom ) instead of launching the full GUI interface, you can source the environment script instead of executing it:
#!/bin/bash # Path to your portable QuestaSim directory export PORTABLE_QUESTA="/home/user/portable/questasim" # Force QuestaSim to use local portable libraries first export LD_LIBRARY_PATH="$PORTABLE_QUESTA/lib:$LD_LIBRARY_PATH" # Point to your license file or license server export MGLS_LICENSE_FILE="27000@your_license_server_ip" # Launch the QuestaSim GUI $PORTABLE_QUESTA/bin/vsim "$@" Use code with caution. Make the script executable: chmod +x questasim_portable.sh Use code with caution. Managing Licenses in a Portable Environment
If you want to run QuestaSim on a modern distro (like Ubuntu 24.04) without worrying about old library dependencies, use Docker. sudo chmod +x questa_sim-2023
You'll need a storage device with sufficient space. A full QuestaSim installation can require 5–12 GB or more, depending on the included libraries and architecture support (x86 vs. aarch64).
To make it truly portable, create a shell script inside the root of your portable folder. This script dynamically sets up the environment paths every time you launch the software, preventing changes to your global Linux configuration. Create a file named launch_questa.sh :
#!/bin/bash # get the directory where this script is located SCRIPT_DIR="$( cd "$( dirname "$BASH_SOURCE[0]" )" && pwd )" If you are using a network license, ensure
