Intel® FPGA Software Licensing
Most Intel FPGA (formerly Altera® FPGA) software requires you to use a license to enable the software. The license is provided in a file named license.dat. This page describes how to get a license file, set up a license, solve a license problem, change license information, and learn about software and intellectual property (IP) licensing options.
- Use the Licensing Quick Start to learn how to license one copy of software on one computer.
- The free Quartus® Prime Lite Edition, Quartus II Web Edition, and ModelSim-Intel FPGA Starter Edition software do not require a license.
An Intel FPGA software subscription enables the Quartus Prime Pro Edition, Quartus Prime Standard Edition, or Quartus II subscription edition software (including the Intel FPGA IP Library) and the ModelSim‑Intel FPGAEdition software. When you purchase a software subscription, the license file supports the version of software you purchase, all previous versions, and all versions released within a year of the purchase date. You can use the version of the Quartus Prime or Quartus II software you purchase, and all related software, including the ModelSim‑Intel FPGA Edition software and the IP Library, indefinitely.
We also use licenses to enable additional software, such as purchased MegaCore functions, the Intel FPGA SDK for OpenCL, and the Intel SoC FPGA Embedded Design Suite (EDS).
