In Nov 2023, we bought several Arty A7-100T boards from Digilent. Just recently my team has found a need to finally use the ethernet MAC feature of the board. I have a few questions. Did our purchase come with the license to use this? If so, how long is the license term (is it 1yr?), where do I find the license info (does it need to installed), and when does the license term start (from the time the boards are received, or if the license needs installation, then when it is installed?)?
