New ContributorError 16045: Instance "auto_fab_0|alt_sld_fab_0" instantiated undefined entity
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.

Super ContributorHi Zhang,
Try to remove your .stp file in your project file or disable signaltap in your setting file and recompile.
Thanks,

JQ2Hi,
The same issue is shown after I disabled the signal tap in Assignments -> Settings -> Signal Tap Logic Analyzer and removed the stp file in the qsf file.
Even I tried to download and compile a clean version of GHRD from (https://rocketboards.org/foswiki/Documentation/Stratix10SoCGSRD), then follow the project build instructions:
make clean && make scrub_clean && rm -rf output_files make sof
same issue happened in the terminal (see attachment snapshot).
This thread (https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/tools/2017/why-does-quartus-give-a-instantiates-undefined-entity-error-when.html ) showed the similar error message. However, it asks me to contact Intel support.
I am compiling the design on our Linux server and this issue suddenly showed up starting this week. When I compare the working syn.rpt and problematic one, I saw difference in the "Synthesis Source Files Read" section (see 2nd snapshot). The working one (right) listed *alt_sld_fab* files as Encrypted Megafunction, while the non-working one (left) showed those files are not Encrypted. Is this the reason that Quartu failed to locate those files later in the report?
If there is other solutions I can try, please let me know. Thanks for all the help.
Regards, JQ
