How to Get QuestaSim for Linux: A Guide to Portable Environments

For FPGA designers and verification engineers working in Linux environments, QuestaSim is the gold standard for HDL simulation. However, the traditional installation process can be heavy, tied to specific root directories, and difficult to move between machines.

If you are looking for a way to "download QuestaSim for Linux portable" style—meaning an installation that is flexible, dependency-contained, and easy to deploy—this guide covers the essential steps and best practices. What is QuestaSim?

QuestaSim, developed by Siemens EDA (formerly Mentor Graphics), is the advanced version of ModelSim. It supports the latest standards in SystemVerilog, VHDL, and Mixed-Signal simulation, offering high-performance verification for complex SoC designs. Why a Portable Approach for Linux?

In a professional Linux environment, you often face several challenges:

Version Conflicts: Different projects may require different versions of Questa.

Dependency Issues: Older versions of Questa might require deprecated libraries (libncurses5, etc.) that aren't available on modern distros like Ubuntu 22.04 or Fedora.

Permissions: You might not have sudo access to install software in /opt.

A "portable" setup allows you to keep the entire toolchain in a single directory or a container, making it easy to share across a team or move between a workstation and a server. 1. Where to Download QuestaSim

Siemens EDA does not provide a "portable .zip" in the traditional consumer sense. To get the official binaries: Visit the Siemens Support Center. Navigate to the Questa Software Download section. Select the Linux 64-bit version. Download the .run or .bin installer.

Note: You must have a valid license or a student/evaluation account to access these files. 2. Making QuestaSim Portable

To achieve a portable-like behavior on Linux, follow these steps: A. The "Local Folder" Installation

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

QuestaSim often relies on specific 32-bit or older 64-bit libraries. To make it truly portable across different Linux distros:

Identify missing libraries using ldd on the Questa binaries (e.g., ldd vsim).

Copy necessary .so files into a libs folder within your Questa directory. Use an environment script to point to these libraries. C. Creating an Environment Wrapper download questasim for linux portable

Instead of modifying your ~/.bashrc, create a script named questa_init.sh inside the folder:

export MGC_HOME=$PWD export PATH=$MGC_HOME/bin:$PATH export LM_LICENSE_FILE=1717@your_license_server # Optional: Point to bundled libs # export LD_LIBRARY_PATH=$MGC_HOME/libs:$LD_LIBRARY_PATH echo "QuestaSim Environment Loaded." Use code with caution.

To run the tool, simply navigate to the folder and type source questa_init.sh && vsim. 3. The Modern Solution: Docker/Apptainer

The ultimate "portable" version of QuestaSim on Linux is a Container. By containerizing Questa, you package the OS, the libraries, and the tool into one image. Portability: Run the same image on Ubuntu, CentOS, or Arch.

Isolation: No need to clutter your host system with legacy libraries.

Deployment: Simply docker pull your verification environment onto any server. 4. Key Considerations

Licensing: Even a portable installation requires a license. Most users use a FlexLM license server. Ensure your portable environment has network access to the server.

Drivers: If you are using Questasim’s hardware acceleration features, you may still need specific kernel drivers installed on the host machine. Conclusion

While there is no official "Questasim Portable" executable, you can create a highly mobile and flexible environment by using local directory installations, custom wrapper scripts, or Docker containers. This ensures your verification workflow remains consistent regardless of the Linux distribution you are using.

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 How to Get QuestaSim for Linux: A Guide

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)

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. Part 1: Understanding "Portable" in the Context of

Portable Stimulus: If you're doing advanced verification, check out the built-in Portable Stimulus capabilities to reuse test scenarios across platforms.

QuestaSim is a proprietary RTL verification tool developed by Siemens (formerly Mentor Graphics). While there is no official "portable" standalone version for Linux, the software can be made effectively portable by installing it into a specific directory and configuring your environment to point to that location. Download Options

Official Siemens Download: QuestaSim is primarily available through a Siemens account. You generally must have a valid license tied to your account to access the download files.

Intel FPGA Edition: A popular alternative is the Questa-Intel® FPGA Edition*, which can be downloaded from the Intel Download Center. This includes:

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

Part 1: Understanding "Portable" in the Context of EDA Tools

Before searching for a download, it's critical to define what "portable" means for complex software like QuestaSim.

Step 2: Relocate the Installation (if needed)

If you already installed it locally, you can copy the entire directory:

cp -r /opt/mentor/questa_sim/2023.3 /media/usb/mentor/questa_sim/

Prerequisites

3. University Programs

Alternative: Pre‑built Portable Images

Some communities package QuestaSim as an AppImage or Singularity container for zero‑install use. Search for questasim-linux-appimage (use at your own risk – respect licensing terms).

What Portable Can Mean for QuestaSim on Linux:

Thus, when users search to "download questasim for linux portable", they often truly want: a way to use QuestaSim on multiple Linux workstations without reinstallation.

System Dependencies – The Real “Non-Portable” Problem

Even if you extract a portable folder, Linux libraries are not bundled:

# Missing libraries typical on modern Ubuntu 22.04 / RHEL 9:
libncurses.so.5  → needs compat package
libstdc++.so.6 (old version) → conflicts with system
libtiff.so.5 vs libtiff.so.6
libXft.so.2 (often absent on Wayland-only installs)

You’ll end up spending more time fixing LD_LIBRARY_PATH than installing the real version.

Step 4: Handling Library Dependencies

QuestaSim requires certain system libraries (libXft, libXext, etc.). On a new Linux machine, you may need to provide them. A portable trick:

Alternative: Run QuestaSim from USB on any machine if that machine has compatible glibc (usually RHEL/CentOS-derived). For Ubuntu, you may need to install libc6-i386 and libxft2:i386.
