Analyze HDL file encrypt_1735

[haianhle]

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,

Let me further confirm with expert and get back to you soon. Please allow some time for it.

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,

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

[ShengN_Intel]

@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.

@ShengN_Intel do you have any update?
