Error 16045: Instance "auto_fab_0|alt_sld_fab_0" instantiated undefined entity

When I was trying to compile the project with Quartus Prime Pro 20.2, I encountered the following issue during the synthesize stage. This issue appeared suddenly, the same design compiled successfull...

    We found the issue. The issue is caused by the update of Digital Guardian software tool on our Linux server. The new version of the tool somehow blocks certain functionality of Quartus, so certain IP files cannot be retrieved. Reverting to a previous version of the Digital Guardian solved the problem.

    Thank you all for the help.

Hi SyafieqS_Intel,

I tried to compile the GHRD project from scratch, and also shorten the project directory, still same error is shown. We also tried to compile using latest Quartus Prime Pro 20.4, same error. I attached the *.syn.rpt here.

Thank you for any advices.
