Description
The problem can occur due to the transceiver settings for the Arria® 10 PCI® Express IP core are not optimal in Quartus® Prime software versions 16.0 and 16.0.1. The existing settings may cause bit errors resulting in link Recoveries and Correctable errors for certain channel loss profiles. These errors are only observed in hardware and not in simulation or during design compilation.
Resolution
This problem is addressed in the Quartus Prime 16.0.2 software update. See this KDB for recommended settings and/or assignments for PCIe designs in Quartus Prime 16.0.2.
