Quartus prime lite : legal for company use?

Yes, it is legally permissible to install Quartus Prime Lite Edition at a company without violating any license agreement.

- Quartus Prime Lite Edition is Intel's entry-level FPGA design software.

- It **does not require a license file** and is available as a free download for both personal and commercial/company use.

- The installer requires you to agree to the Intel License Agreement before proceeding, but this is standard and does not restrict company use. you may refer to https://www.intel.com/content/www/us/en/docs/programmable/683472/24-3/installing-fpga-software-through-installer.html

I would strongly suggest you click the Intel License Agreement link to view it in your default browser following the steps above.
