Cyclone IV GX project failed migration from 18.1 to 20.1 - Cyclone IV GX project failed migration from 18.1 to 20.1 As per title, I decided it was time to migrate an old project from Quartus 18.1 to 20.1. It's a Cyclone IV GX PCIExpress design and on compilation I get the errors: Error (12252): Altgx_internal: error copying "C:/intelfpga_lite/20.1/quartus/../ip/altera/ip_compiler_for_pci_express/lib/altpcie_serdes_3cgx_x1d_gen1_08p.v": no such file or directory Error (12252): Altgx_internal: Generation callback did not provide a top level file (expected `add_file $output_dir/pcie_qsys_pcie_hard_ip_0_altgx_internal.v|vhd|sv {SIMULATION SYNTHESIS}`) It doesn't matter whether I run the migration wizard or not, same error. Any ideas Replies: Re: Cyclone IV GX project failed migration from 18.1 to 20.1 This error - " Error (12252): Altgx_internal: error copying "../altpcie_serdes_3cgx_x1d_gen1_08p.v": no such file or directory" is still showing up when generating HDL in the Platform Designer for the design that has PCI Express IP. I have version 22.1std.1 Build 917 Lite Edition. This seems like an issue that should have been fixed.

Replies: Re: Cyclone IV GX project failed migration from 18.1 to 20.1 Hi, Can you try to copy the following directory from 18.1 into same location in whatever newer release(20.1 and 21.1): \18.1\ip\altera\ip_compiler_for_pci_express Regards, Wincent_Intel Replies: Re: Cyclone IV GX project failed migration from 18.1 to 20.1 No progress on this problem so please don't close it. Replies: Re: Cyclone IV GX project failed migration from 18.1 to 20.1 So I tried regenerating the design, no joy, same error. The KBD mentions the same error code but with a different error message, so no help there. Still stuck unfortunately. Replies: Re: Cyclone IV GX project failed migration from 18.1 to 20.1 Hi, I wish to follow up with you about this case. Do you have any further questions on this matter ? Else I would like to have your permission to close this forum ticket Regards, Wincent_Intel Replies: Re: Cyclone IV GX project failed migration from 18.1 to 20.1 Hi, We do not recommend direct migration as some feature might be miss match. I suggest you to regenerate a new design using Quartus v20.1. Alternatively, you can try below KDB and see if it is able to resolve your problem or not. https://www.intel.com/content/www/us/en/support/programmable/articles/000078024.html Regards, Wincent_Intel
