I own an Arria 10 GX Dev Kit ES2, bought in early 2017. At the time I used it with Quartus 15.1 with one year license. Of course license expired so I tried to use it with my current Quartus 18. To my surprise the Arria 10 GX ES2 is not anymore supported! I have asked intel to know which is the way to use my board with my current license, so far no answer from them. A renewal for my old 15.1 dev kit license costs 4K USD, that is to say, the same price than a new license (btw, 15.1 does not accept my new license). Does anyone know how this license stuff work?
