Aufgrund eines Problems in den Quartus Prime® Software-Versionen 16.1.2 und früher könnte Ihr Arria® 10 SerialLite™ III Kern in den Pfaden zwischen "pld_10g_tx_pempty_reg Knoten" und "altera standard synchronizer stdsync_txpempty|din_s1" des unten gezeigten Typs Verletzungen des Setup-Timings aufweisen:

Um dieses Problem zu umgehen, muss der Benutzer die generierte ip.sdc-Datei (seriallite_iii_streaming*.sdc) ändern.
