Analyze HDL file encrypt_1735

I encrypted the hdl file with encrypt_1735 (dti_phy_ctl_blk.v -> dti_phy_ctl_blk.vp)

"encrypt_1735 dti_phy_ctl_blk.v --language=verilog --quartus"

then I took that file to analyze and got an error:

Error: Internal Sub-system: QIS, File: /quartus/synth/qis/qis_rtl_stage_utility.cpp, Line: 705

Error: No modules found when analyzing [PATH]/dti_phy_ctl_blk.vp.

How can I synthesize encrypted files?

Thanks and best regards

    Hi,


    If you already have the encryption key, do the followings:

    1. Encrypt the design with IEEE 1735. Command line used: encrypt_1735 --quartus --language=verilog counter.v
    2. File counter.vp will be generated in the file folder.
    3. Open a new project, add counter.vp in the project. Set it as top-level entity.
    4. Right click on the counter.vp. Select Properties. Ensure the Type: Verilog HDL File.
    5. Run Analysis & Synthesis.


    Thanks,

    Best Regards,

    Sheng

      I have successfully Run Analysis & Synthesis file dti_phy_ctl_blk.vp

      But I want to create components from my design so I use Platform Design

      --------

      I use Platform Design to create new components

      1. I add dti_phy_ctl_blk.vp

      2. Set type Verilog HDL

      3. Set Attributes is Top-Level file

      4. Run Analyze HDL Files

      Then I got that error

      Error: Internal Sub-system: QIS, File: /quartus/synth/qis/qis_rtl_stage_utility.cpp, Line: 705

      Error: No modules found when analyzing [PATH]/dti_phy_ctl_blk.vp.

      How can I finish creating a new component.

    Hi @haianhle ,

    Internal expert feedback:

    Qsys invokes quartus_syn for the analysis of the HDL files. I don't think Quartus can decrypt unknown encrypted files, so this is expected behavior that it would fail on analysis of encrypted files

    Thanks,

    Best regards,

    Sheng

      I encrypted the hdl file with encrypt_1735(Quartus encrypt tool). So I think it is not unknown encrypted files

        @haianhle Based on internal feedback, unknown encrypted files also include Quartus encrypt tool (encrypt_1735). Feedback as below:

        Is the file encrypted with the altera key?

        If it is quartus synthesis can analyze it. Otherwise it can't.
