Altera offers the popular Quartus development software for Intel FPGAs. A frequent question we receive is how to renew your license for this software, once its one-year duration has expired.
In short: this license does not renew inasmuch as there is no reduced-cost ‘renewal’ license or subscription. To renew your access to software updates and support, you will need to purchase a new license at the original price.
For additional information, Intel has a few different resources you can make use of, and we have an additional post focusing on Quartus questions as well:
