Information about cyclonev_termination_logic_encrypted, cyclonev_dll_encrypted

Hello,

I try to simulate a DDR3 Uniphy design with ModelSim . I use Mentor Graphics Hdl Author tool to manage my libraries and launch Modelsim from this tool.

My design uses some of altera libraries, so that I mapped these compiled libraries accordingly. After I start ModelSim simulation ends with the following errors:

..../quartus/eda/sim_lib/cyclonev_atoms.v(3714): Instantiation of 'cyclonev_termination_encrypted' failed. The design unit was not found.

I get the same message for the title files as well. Please note that my version of Quartus is 13.1 web edition and some features might not be available. But can you confirm these 3 files are to be found only in the Quartus Subscription edition , or should I look for the root of the problem somewhere else?

Many thanks,

Florin

    Does the file exist as part of your installation? It may be it's looking in the wrong path.

    For anyone else out there who comes across this issue. Here is the reply from Altera support

    "The cyclone_atoms.v instantiante the encrypted modules (e.g cyclonev_dll_encrypted, cyclonev_termination_logic_encrypted, ect) which is found in cyclonev_atoms_ncrypt.v & cyclonev_hmi_atoms_ncrypt.v files. The encrypted files for mentor is found in <drive>:\altera\13.1\quartus\eda\sim_lib\mentor directory.

    When you generate the simulation models for qsys system that contain LPDDR2 and custom components, it should generate the msim_setup.tcl file which is placed in ~\testbench\mentor directory. It should compile, load and simulate the system successful if you execute the generated msim_setup.tcl file.

    But. you can actually also refer to this script if you want to create your own custom script to perfom simulation for your design."

    So the missing libraries are in the sim_lib\mentor\ directory and need compiled

    e.g.

    vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/mentor/cyclonev_hssi_atoms_ncrypt.v" -work cyclonev_hssi_ver
