Description
Data Link Layer active reporting and Surprise Down reporting cannot be enabled for the Avalon® MM interface for PCIe Solutions in software versions 15.0 and earlier. Hence the derr_cor_ext_rpl, derr_rpl, dlup and dlup_exit signals do not indicate any useful information and should be ignored.
Resolution
This functionality has been added to software version 15.0.1 and later of the Quartus® II software.
