Due to a problem with version 14.1 of the Quartus® II software, you may see this error when the Arria® 10 PCI Express® Hard IP with the config bypass feature enabled.
Copy the altpcierd_hip_rs.v file from the <Quartus II install>/ip/altera/altera_pcie/altera_pcie_a10_ed/example_design/verilog/chaining_dma directory to the <variation>/altera_pcie_a10_hip_141/synth directory. Add the following line to your <variation>/<variation>.qip file:
set_global_assignment -library <variation> -name VERILOG_FILE [file join $::quartus(qip_path) "altera_pcie_a10_hip_141/synth/altpcierd_hip_rs.v"]
This problem is scheduled to be fixed in a future version of the Quartus® II software.
