Our company is currently using Quartus II version 14.0. But we need to use a later version of Quartus for a new project that uses Arria 10 or Cyclone 10.
We have a license that works for 14.0, the version is 2018.03, and it's permanent. We tried it on Quartus 21.2 and the license didn't work.
We don't want to purchase a new license, and are fine with using version 17.x or 18.x.
Could you let us know which version of Quartus is our license good for?
