You are running simulation in cadence tool but the simulation library is pointed to Mentor: quartus/eda/sim_lib/mentor/twentynm_atoms_ncrypt.v
You have to change to the simulation library to Cadence.
Hi, Sorry for my late reply.
I have solved this using cadence 's twentynm_atoms_ncrypt.v file.
I found that the cadence 's twentynm_atoms_ncrypt.v files. are only available in linux version quartus, not be available in windows version.
but this is not descripted in user-gudie. I suggest this information should be added in user-guide.
Thanks for your support !!
May I know the edition(Pro/Standard) and version of the Intel Quartus Prime software you are using?
Hi, I used Quartus Prime 16 build 211 Standard version.
