For a complete installation, you need three main components:
ModelSim-Altera Starter Edition (optional) – For simulation. Version 10.1d is recommended for compatibility with Quartus 13.0.
⚠️ Warning: Do not download from random file-sharing sites like "4shared" or "Rapidgator." They often host tampered executables. Always verify the digital signature of the installer.
Downloading Altera Quartus II 13.0 for free is a straightforward process if you go directly through Intel’s official website. Avoid shady third-party sites, follow the licensing steps carefully, and you will have a fully functional FPGA development environment for legacy devices.
Remember: the free Web Edition is perpetually free – no trial expiry, no feature limitations for supported devices. Intel continues to host this software out of respect for the massive installed base of Cyclone II and MAX II designs.
If you encounter issues, refer to Intel’s Knowledge Base or community forums like reddit.com/r/FPGA – many users still actively support Quartus II 13.0.

Altera Quartus II 13.0 Free Download: Essential Guide for Legacy FPGA Support
The Altera Quartus II version 13.0, specifically the 13.0 Service Pack 1 (SP1), remains one of the most sought-after legacy design suites in the FPGA community. It is uniquely critical for developers and students because it is the last version to support several iconic legacy hardware families that are now excluded from modern Intel Quartus Prime releases. Why You Need Quartus II 13.0 SP1
The primary reason to download this specific version is hardware compatibility. Modern versions of Quartus Prime (Lite, Standard, or Pro) have dropped support for several "classic" chips still widely used in education and older industrial applications.
Cyclone II Support: This is the final version that allows you to program Cyclone II FPGAs, commonly found on popular development boards like the Terasic DE1 and DE2.
Legacy CPLDs: It is the last official release to support MAX 3000 and MAX 7000 CPLD families. For a complete installation, you need three main components:
Reliable for Cyclone III: While newer versions briefly supported it, 13.0 SP1 is often preferred for Cyclone III designs due to faster compilation and more stable legacy IP. Key Features of the Web Edition (Free)
The Web Edition of Quartus II 13.0 is a free-to-use version that does not require a paid license for most standard FPGA development tasks.
Comprehensive Tools: Includes analysis and synthesis of HDL designs (Verilog/VHDL), timing analysis, and RTL diagram examination.
ModelSim-Altera Starter Edition: Frequently bundled with the free download, this allows for full design simulation without a separate license.
Qsys System Integration: Features the Qsys tool for connecting IP cores, including a reset controller that prevents memory corruption after asynchronous resets. Quartus II 13.0sp1 | Altera Community - 312724
While this version is excellent for legacy devices, consider these alternatives if you use newer FPGAs: ⚠️ Warning: Do not download from random file-sharing
| Software | Best For | Free? | |----------|----------|-------| | Quartus Prime Lite 18.1+ | Cyclone V, Cyclone 10 LP, MAX 10 | Yes | | Quartus Prime Standard Edition | Arria V, Cyclone V, Stratix V | Paid | | Quartus Prime Pro Edition | Stratix 10, Agilex | Paid | | Vivado HLx (Xilinx) | Xilinx FPGAs (non-Altera) | Free WebPack |
If you are still using Cyclone II, Quartus II 13.0 remains your only official option.
Even the free Web Edition requires a license file. Here is how to generate one:
Visit Intel’s Self-Service Licensing Center:
Download the license file (license.dat). Save it to a permanent location (e.g., C:\altera\13.0\license.dat).
Point Quartus to the license:
Troubleshooting: If you get "Invalid license" errors, ensure the NIC ID matches your primary adapter. Disable virtual adapters (VirtualBox, VPN) temporarily.
