eda sim_lib vlog compile error...missing tennm_atoms_ncrypt.sv - eda sim_lib vlog compile error...missing tennm_atoms_ncrypt.sv Trying to conpile eda sim_libs for Mentor and getting an error about missing .sv file. Error is below. Error: # ** Error: (vlog-7) Failed to open design unit file "/apps/quartus_prime/19.2.0/install/quartus/eda/sim_lib/mentor/tennm_atoms_ncrypt.sv" in read mode This file seems to exist in some versions of Quartus (found it in 19.4) but not in others. Where do these files come from? Why are they differnet from version to version? Should I have tennm_atoms_ncrypt.sv in 19.2 or 19.3 sim_libs? Thanks for any replies! Replies: Re: eda sim_lib vlog compile error...missing tennm_atoms_ncrypt.sv Thank you, that worked. I installed the Agilex device family and the missing files appeared. Please note that Agilex devices are not supported until 19.3. Replies: Re: eda sim_lib vlog compile error...missing tennm_atoms_ncrypt.sv Yes, once you installed the Agilex device, the .sv file will be shown. Replies: Re: eda sim_lib vlog compile error...missing tennm_atoms_ncrypt.sv Thanks for the reply. Does that mean those .sv files will not show up unless I install the agilex device family maybe?? Replies: Re: eda sim_lib vlog compile error...missing tennm_atoms_ncrypt.sv I believe the files is used for Agilex devices. I checked, starting from Quartus Pro version 19.1 and onwards you should be able to see the tennm_atoms_ncrypt.sv files located in the <installation directory>/quartus/eda/sim_lib/mentor/
