Simulating Arria10 designs in Verilog - twentynm_atoms_ncrypt.v

Have you compiled all of the FPGA device libraries into their respective libraries in Questa Standalone version. The ModelSim intel version comes with these already pre-compiled. If using other versions, you need to manually compile all of the files into the libraries and then compile your design.

You must compile Altera simulation model files before simulating an Altera design. The Quartus II software includes simulation models for Altera megafunctions, primitives, library of parameterized modules (LPMs), IPFS models, and device family specific models in the <installation path>/eda/sim_lib directory.
