Karena masalah dalam perangkat lunak Quartus Prime® versi 16.1.2 dan sebelumnya, inti Arria® 10 SerialLite™ III Anda mungkin menunjukkan pelanggaran pengaturan waktu di jalur antara "pld_10g_tx_pempty_reg node" dan "synchronizer standar altera stdsync_txpempty|din_s1" dari jenis yang ditunjukkan di bawah ini:

Untuk mengatasi masalah ini, pengguna harus mengubah berkas .sdc ip yang dihasilkan (seriallite_iii_streaming*.sdc).

Masalah ini telah diperbaiki mulai di perangkat lunak versi 17.0 dari perangkat lunak Quartus Prime®.
