N/A until Partition Merge - N/A until Partition Merge Good morning, thank you very much for helping me, I am worried because the Quartus is the controller of the Altera Cyclone IV card. I have reinstalled the Quartus 3 times, I gave it permissions so that the antivirus can avoid deleting its files. Before installing it, for the third time, I deleted the temporary files. Quartus doesn't compile! It always gets up to 47%. Any ideas? Thank you very much.
