Bug ID: FB: 514010;

Why does synthesis of Intel® Arria® 10 PCIe* IP generated with VHDL return Error(16045) - ""u_global_buffer_coreclkout" instantiates undefined entity "altera_global""?

Description

Due to a problem with the Intel® Quartus® Prime software version 17.1, the altera_global component entity alias in VDHL is not mapped to the correct VHDL altera_global entity. 

Workaround/Fix

In the PCIe* top-level VHDL instantiation file, for example pcie_pcie_a10_hip_0.vhd, comment out these two lines of VHDL code.  Then re-run the implementation. 

  for pcie_a10_hip_0 : pcie_pcie_a10_hip_0_altera_pcie_a10_hip_171_<random string>_cmp

        use entity altera_pcie_a10_hip_171.pcie_pcie_a10_hip_0_altera_pcie_a10_hip_171_<same random string>; 

This problem is scheduled to be fixed in a future Intel® Quartus® Prime software release.
