Portable does not mean free. You still need access to a valid Siemens EDA license server or a local license file ( mgls_licensee or LM_LICENSE_FILE ). Step 2: Structuring the Portable Directory
8 GB RAM minimum; 16 GB or higher recommended for complex SystemVerilog/UVM environments. Supported Linux Distributions
| Distribution Channel | Typical Versions | License | Best For | | :--- | :--- | :--- | :--- | | | Latest (2024.1, 2025.2) | Paid commercial license | Companies, institutions | | Intel FPGA Starter Edition | Version matching Quartus | Free (registration req'd) | FPGA development, students, hobbyists | | Academic Programs | Various versions | Free for approved institutions | University courses, research | | Community Resources / Forums | 10.7c, 2021.x, older | Varies (often community patches) | Testing legacy designs, learning |
You can download the latest installer files—often identified as .tgz or .aol files—and extract them using tools like tar xfva . This creates a standalone directory that can theoretically be moved between systems, provided the target system has the necessary libraries. download questasim for linux portable
To make the installation portable (e.g., on a removable drive), install it into a single folder rather than system directories like /opt .
Questasim requires 32-bit libraries to function, and these are the most common missing pieces when moving between systems.
With the structure built and the wrapper script defined, verify your portable environment by calling the simulator's version diagnostic flag from the terminal. ~/portable_eda/questasim_portable.sh -version Use code with caution. Portable does not mean free
that uses an older, stable base like Ubuntu 18.04 or 20.04.
When writing scripts ( compile.do or run.do ), never use hardcoded absolute file system paths. Always use relative notation ( ./src/sim_top.v ) so your entire testing suite moves seamlessly alongside the tool.
export QUESTA_HOME="$SCRIPT_DIR/questasim" # Adjust path as needed export PATH="$QUESTA_HOME/bin:$PATH" export PATH="$QUESTA_HOME/linux_x86_64:$PATH" Questasim requires 32-bit libraries to function, and these
docker run -it --rm \ -e DISPLAY=$DISPLAY \ -v /tmp/.X11-unix:/tmp/.X11-unix \ -v /home/user/projects:/workspace \ -v /path/to/license.dat:/opt/mentor/license.dat \ questasim:portable vsim Use code with caution.
However, using the combined with a Floating License is the best pragmatic approach for moving the software across different Linux machines. If you need "set it and forget it" reliability across completely foreign systems, the Docker or VM approach will save you hours of troubleshooting missing system libraries.
