PCIe Example Design Simulation Failing

Unsing Quartus 18.1 Pro. Generated Gen2x1 or Gen3x4. When compiling in modelsim, I get the following:

When checking the path, the file does not exist. Thank you.

    Hi,

    We acknowledge the issue and will gt back on this,

    Also checked with Modelsim 10.6C which gives same error.

    Best Regards,

    Based on my investigation, it's probably not due to Modelsim version... It looks more like a qsys generation problem. On that, note that I've tried 17.1 Pro as well with the same outcome. When examining the example design log I do see:

    Info: pcie_example_design_inst_board_pins_bfm_ip: "Generating: pcie_example_design_inst_board_pins_bfm_ip_altera_conduit_bfm_181_o4cgbkq"

    But the file is nowhere to be found... I've tried running as admin to rule out the permissions, I looked into the temp folder it appears to use but it looks like its hidden in a _db file.

    Thanks your help,

    By any chance, are you running on Windows? I had the same (or similar) problem a while ago and it came down to the path length ending up being stupidly long...

    Hi Andy, yes Windows. I was actually careful of that and generated the example design at the C:/ level.

    Also, there is a pkg file generated at the same depth... so should not be an issue. An Intel FAE colleague also reported that he had observed the same issue...

    Thanks,

      Hi， SLabe，I got the same simulatioan error and indeed could not generate the simulation file named "pcie_example_design_inst_board_pins_bfm_ip_altera_conduit_bfm_181_o4cgbkq.sv" . OS of my computer is Win10 , version of Quartus Prime Pro Eniton is 18.1 and simulation tool is Questa Sim-64 10.6c. I got error messages as follows, do you know how to fix it now? Thank you very much.
