Starter Edition: Free to use but requires a zero-cost license. Standard Edition: Requires a paid license. How to Create a "Portable" Setup on Linux
Since QuestaSim is modern 64-bit software, it can be installed in a custom directory (e.g., /home/user/questasim) and moved between systems if dependencies and licensing are handled. Part 1: Installing QuestaSim - University of Florida
QuestaSim does not offer an official "portable" version (like a single-file executable) for Linux. However, it can be made portable by manually extracting and managing the installation directory or by using containerization like Docker to avoid dependency conflicts across different distributions. Portability & Installation Review
Because QuestaSim is a commercial tool with complex library dependencies, true portability requires specific setups:
Extraction Method: 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.
System Compatibility: QuestaSim is a modern 64-bit software, but it often requires specific 32-bit libraries (e.g., libxft2:i386, lib32ncurses6) to run correctly on modern distributions like Ubuntu or Arch Linux. download questasim for linux portable
The Docker Solution: For a truly portable experience that works on any Linux OS, users often recommend Docker. This encapsulates the required OS environment and libraries, preventing the "dependency hell" that occurs when moving the software between different Linux distributions. User Experience & Performance
Users typically find QuestaSim to be a robust successor to ModelSim, though it has high licensing and setup requirements.
“QuestaSim is Intel's successor to ModelSim... modern, 64-bit software. Since QuestaSim shares most of its CLI with ModelSim, you can nearly use Questa as a drop-in replacement.” Machine Intelligence Laboratory (MIL)
“Questa is officially supported on Redhat EL and Suse ES, however, in my experience it works on most if not all distros... Questa is available for both 32 and 64bits platform.” SIEMENS Community · 4 years ago Key Considerations
Licensing: Even with a portable file structure, the software requires a valid license (e.g., license.dat) and specific environment variables like LM_LICENSE_FILE to function.
Editions: You can download the Questa Starter Edition through the Intel Download Center, which is often used for academic or light non-commercial learning. Running Questasim on any OS through Docker - REDS blog

To set up QuestaSim for Linux in a "portable" fashion, you can avoid system-wide installation by using Docker or a standalone local directory setup.
Here is a full blog post covering the download, setup, and "portable" configuration for Linux. How to Set Up QuestaSim for Linux: The Portable Guide
Running high-end EDA tools like QuestaSim on modern Linux distributions can be a headache due to library conflicts. Whether you're moving between workstations or want to keep your OS clean, a portable setup is the best way to go.
In this guide, we'll cover how to download and configure QuestaSim for Linux without "installing" it in the traditional, system-cluttering sense. ⚡ The "Portable" Strategy True portability in Linux comes from two methods:
Local Directory Setup: Keeping the entire installation in a single folder (e.g., /opt/questasim) and using script-based environment variables.
Docker Containers: The ultimate portability. Package QuestaSim and its specific library dependencies into an image that runs on any distro. 📥 Step 1: Download Questasim
Siemens (formerly Mentor Graphics) does not provide a direct public "portable.zip" file. You must download the installer from an official source:
Intel FPGA Edition: The most common way for students and hobbyists to get Questasim is via the Intel FPGA Download Center. Look for "Questa*-Intel® FPGA Edition".
Siemens Support Center: Professional users can download the full version from the Siemens EDA Support Portal. File types to look for: .run (Self-extracting installer) .aol (Mentor Graphics install format) 🛠️ Step 2: Portable Installation (Local Folder) While there is no official "portable" version of
Instead of installing to /usr/local, choose a dedicated path like ~/eda/questasim. 1. Install Dependencies
Questasim is often 64-bit now, but older versions or specific sub-tools still require 32-bit libraries.
# Example for Ubuntu/Debian sudo apt install libxft2 libxext6 libncurses5 Use code with caution. Copied to clipboard 2. Run the Installer Launch the installer and point it to your local directory.
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
To make it portable, you don't want to edit your ~/.bashrc permanently. Instead, create a wrapper script (run_questa.sh) inside your folder:
#!/bin/bash # run_questa.sh PORTABLE_ROOT=$(pwd) export PATH="$PORTABLE_ROOT/questasim/linux_x86_64:$PATH" export LM_LICENSE_FILE="$PORTABLE_ROOT/license.dat" vsim "$@" Use code with caution. Copied to clipboard
Now, you can move the entire folder to another machine and just run ./run_questa.sh. 🐳 Step 4: The Docker Approach (Highly Recommended)
If you want to run QuestaSim on a modern distro (like Ubuntu 24.04) without worrying about old library dependencies, use Docker.
Create a Dockerfile that uses an older, stable base like Ubuntu 18.04 or 20.04.
Mount your project as a volume so your code stays on your host machine while the simulator runs inside the container. 💡 Quick Tips for Success
License Path: Always use an absolute path in your LM_LICENSE_FILE variable to avoid "License not found" errors when switching directories.
Check vsim: Run vsim -version immediately after setup to verify that all shared libraries (.so files) are correctly linked.
Portable Stimulus: If you're doing advanced verification, check out the built-in Portable Stimulus capabilities to reuse test scenarios across platforms.

The pursuit of high-performance digital simulation often leads engineers to QuestaSim, a premier tool for Verilog, SystemVerilog, and VHDL verification. While Siemens EDA typically provides QuestaSim through a formal installation process involving complex directory structures and environment variables, the concept of a portable Linux version has become highly desirable. A portable installation allows engineers to maintain a consistent verification environment across different machines without the need for root privileges or repetitive installation steps. Achieving this requires a deep understanding of Linux library dependencies, license management, and shell configuration.
The primary challenge in creating or obtaining a portable version of QuestaSim for Linux lies in its reliance on shared system libraries. Like most EDA tools, QuestaSim is compiled against specific versions of libraries such as glibc, libX11, and various motif packages. On a standard installation, these are managed by the OS package manager. To make the software portable, one must use a "bundled" approach, where all necessary .so files are contained within the application folder. Tools like AppImage or simple wrapper scripts that modify the LD_LIBRARY_PATH are commonly employed to ensure the binaries look within their own directory for dependencies rather than the host system's /usr/lib folders.
Beyond the binaries themselves, the licensing mechanism is the most significant hurdle for portability. QuestaSim utilizes the FlexNet Publisher (FlexLM) system, which typically anchors a license to a specific hardware MAC address or a Host ID. For a truly portable setup, users often utilize a floating license server. In this configuration, the portable QuestaSim folder contains a pointer—usually the MGLS_LICENSE_FILE environment variable—to a central server. This allows the user to move the software folder to any machine on the network, execute the simulator, and check out a license dynamically, fulfilling the requirement of mobility without violating compliance.
Setting up the environment is the final step in the portability workflow. Since a portable version does not integrate with the system path, a "sourcable" shell script is essential. This script should define the QUESTASIM_HOME, update the PATH to include the compiler and simulator executables (vlog, vcom, vsim), and set the necessary locale variables to prevent font or display errors in the graphical user interface. By encapsulating these settings in a single script, the user can initialize the entire toolchain in seconds on any compatible Linux distribution.
In conclusion, while a "downloadable" portable version of QuestaSim is rarely provided directly by the vendor, it is a configuration that can be engineered through careful file management and environment tuning. The ability to run such a powerful simulation suite from a USB drive or a synced cloud folder provides immense flexibility for hardware designers. However, users must remain diligent regarding library compatibility between different Linux kernels and ensure that their licensing solution supports a mobile infrastructure. As remote work and decentralized engineering teams become the norm, the demand for these portable EDA environments will only continue to grow.
