Why does the Arria 10 Hard IP for PCI Express transmit bad TLPs or bad DLLPs when sending traffic?

Description

When the Arria® 10 Hard IP for PCI Express® transmits packets, its link partner may report bad TLPs or bad DLLPs.  These Correctable Errors may result in lower throughput.  An incorrect Hard IP bit setting causes these errors.

Resolution

If using Quartus® Prime v15.1.2, patch 2.03r can be obtained via MySupport.

This problem has been fixed in Quartus Prime 16.0.  Upgrade and regenerate the PCIe® Hard IP core and recompile your design.
