Compilation on quartus tool fails for encrypted verilog and verilog header files

I assumed that the third-party tool support IEEE1735.

Does the files encrypted using the Quartus public key? File encryption with a third-party tool requires the public encryption key.

Hi Richard,

I went through the document and video. It shows how to encrypt and decrypt the design using Intel Key.

My concern is different. The third party IP is from synopsys. It is already encrypted. So the Quartus is not able to compile it.

With Xilinx Vivado, in such cases, we can launch the Synplify pro. using Vivado and then such RTL which is encrypted one can be compiled and synthesized for a specific FPGA target family. Once synthesis is done, the netlist is used further in the main flow for compilation.

So I think similar process could be there with Quartus tool but I was not able to find the same ?

Is there an option to launch the third party synthesis process with third party tool such as synplify pro and target the process for a specific Intel FPGA family ? Then I could be at-least generate the netlist and then use it in main compilation flow.

Could you try to set the synthesis tool to Synplify Pro in Quartus? Go to Setting > EDA Tool Settings > Design entry/ synthesis > Synplify Pro.

Usually third party encryption tool will need Quartus public key to encrypt then the Quartus can compile it.

The documentation that I found about Synplify support:

Hi Richard,

I tried all the steps that you had mentioned.

The tool is not able to find where the synplify pro is located.

I do not have synplify pro license. We are checking whether can we have evaluation license to try out. IT team is working on it.

Also I had raised query related to public Key to be used on intel support platform. But they guided me that I cannot use the support platform to get the key.

To whom should I contact or can I request you to obtain the public key ?

Hi Richard,

As evaluation license borrowing of Synplify is in process, I wanted to check that where we should mention in Quartus tool about this synplify tool installation path ?

https://www.intel.com/content/www/us/en/docs/programmable/683796/18-1/using-the-software-to-run-the-synplify.html

In above document, it is mentioned that:

To set up the Intel® Quartus® Prime software to run the Synplify software, do the following:

1. On the Tools menu, click Options.
2. In the Options dialog box, click EDA Tool Options and specify the path of the Synplify or Synplify Pro software under Location of Executable.

We are using Quartus Prime Software version 22.3

I was able to see Tools menu -> Options.

But did not find out "EDA Tool Options".

We have removed the EDA Tool Option GUI in Quartus Pro.
