To ensure you are getting a clean, virus-free installer, you should always use official channels. 1. The Siemens Support Center (Official Method)
This is the only legal and secure way to obtain the software. Step 1: Go to the Siemens Support Center.
Step 2: Register for an account. Note that you usually need a Site ID (provided when your company or school purchases a license) to access downloads. Step 3: Search for "Questa" in the product list.
Step 4: Navigate to the "Downloads" section and use the version dropdown menu to select 10.7c.
Step 5: Choose the installer for your OS (Windows 64-bit or Linux 64-bit). 2. Academic/University Portals
If you are a student, many universities provide a local mirror or a VPN-protected link to download QuestaSim. Check your Electrical Engineering or Computer Science department’s software portal. Often, these downloads come pre-configured with the university's license server settings. System Requirements for 10.7c
Before you start the hefty download (usually several gigabytes), make sure your machine is ready: OS: Windows 10 (64-bit) or RHEL/CentOS 7/8 for Linux users.
RAM: Minimum 8GB, though 16GB+ is recommended for large SoC simulations. Disk Space: At least 5GB for the installation.
Java: Some GUI components require a specific JRE version, usually bundled with the installer. Installation & Licensing Tips
Once you’ve downloaded the questasim-10.7c.exe (Windows) or the .run file (Linux):
Run as Administrator: On Windows, right-click the installer and select "Run as Administrator" to avoid permission errors in the C:\questasim64_10.7c directory.
Environment Variables: You must set your LM_LICENSE_FILE environment variable to point to your license server (e.g., 1717@your-server-name).
Pathing: Add the \bin folder to your system PATH so you can launch vsim from any terminal or command prompt. Common Troubleshooting
Missing DLLs: If you get a "mgls64.dll" error, it’s almost always a licensing issue. Re-check your environment variables.
Linux Libraries: On newer Linux distros (like Ubuntu 22.04), you might need to install legacy 32-bit libraries (like libXft or libncurses) even for the 64-bit version of QuestaSim. Final Thoughts
Downloading QuestaSim 10.7c is the first step toward high-level hardware verification. While it might be tempting to look for "cracked" versions on third-party sites, these often contain malware or are unstable for long simulation runs. Stick to the Siemens portal or your institution's resources for a clean setup.

Before beginning the installation, ensure your workstation meets the following minimum specifications: Questa One Sim | Siemens
* Overview. * Solutions. DFT Verification. Functional Safety. Unified Coverage. AI/ML. Trust and Assurance. Low Power. * Products. Questa® SIM GUI Reference Manual
The phrase "make feature" in the context of QuestaSim 10.7c typically refers to utilizing a Makefile to automate the compilation and simulation flow, rather than a built-in "feature" button within the GUI.
In professional verification environments, using a Makefile is the standard way to manage complex designs, as it allows you to run simulations from the command line without manually typing commands into the QuestaSim transcript. Implementing a "Make" Flow for QuestaSim
To use this "feature," you create a file named Makefile in your project directory. Below is a standard template for QuestaSim 10.7c:
# Variables VLIB = vlib VLOG = vlog VSIM = vsim WORK = work # Default target all: lib compile sim # Create the work library lib: $(VLIB) $(WORK) # Compile source files (Verilog/SystemVerilog) compile: $(VLOG) -work $(WORK) top.v dut.v testbench.sv # Run simulation in command line mode (batch) sim: $(VSIM) -c -do "run -all; quit" $(WORK).top_tb # Run simulation with GUI gui: $(VSIM) -i -do "add wave *; run -all" $(WORK).top_tb # Clean up simulation files clean: rm -rf $(WORK) transcript vsim.wlf Use code with caution. Copied to clipboard How to use it
Open your terminal (Linux) or Command Prompt/PowerShell (Windows with MinGW/Cygwin). Navigate to your project folder. Run commands:
make — Executes the full flow (lib, compile, and batch sim).
make gui — Compiles and opens the QuestaSim GUI with waves added automatically.
make clean — Wipes the library and log files to start fresh. Why use Make in QuestaSim 10.7c?
Speed: It only recompiles files that have changed since the last run.
Reproducibility: Ensures every team member runs the simulation with the exact same flags and arguments.
Integration: Essential for Continuous Integration (CI) pipelines where a GUI is not available.
For official documentation on command-line arguments like -c (command line) or -i (interactive), you can refer to the Siemens EDA (formerly Mentor Graphics) support portal.
