Fatal Error: Segment Violation at (nil)

[JobvW]

Hello, I am trying to synthesize my vhdl code, but when I run synthesize in Quartus prime I get this error. The only thing I can find is that there is a patch for Quartus prime pro, but I am using Quartus prime lite.

In my vhdl code I am trying to write a vga controller.

I am using a MAX10 10M50DAF484C7G fpga.

If anybody can point me in the right direction I would be grateful, thanks in advance.

Hi,

Thanks for attaching the files. However, can you archive your project, so that I can restore the complete project and ensure that no files are missing?

In Quartus, Open the project > Project > Archive Project.

Afterwards, you may upload the compressed .qar file. Thanks.

You may check out the link on archiving projects:

Thanks for your reply, I created the archive altho as expected I got the same error message, so not all files are included in the archive.

This was the error message after the archiving:

Project archive created; however, Analysis and Elaboration (or Analysis and Synthesis for export database) was not successful. As a result, some files could not be archived.

Greetings,

Hi,

Thanks for attaching the file.

Can you send the patch that you found for Quartus Prime Pro, so that I can investigate more on this error?

Thanks.

Best Regards.

Hello,

No problem, I tried this one.

Thanks for attaching the link.

I will check this with the Engineering Team.

Thanks.

FYI, Engineering Team requires some time to investigate further to the Fatal Error. Kindly stay tuned with us.

Thanks.

Hi,

From the latest update from the engineering team:

They found the line that's causing the issue:

In vhdl/common_pkg.vhd, the definition of function c_t_char_array_init, if "x(32-1 DOWNTO 0) := STD_LOGIC_VECTOR(TO_UNSIGNED(I, 32));" is commented out, the program will be able to compile successfully.

They were able to resolve the IE with RTL changes and provide the workaround. The two files modified are total.vhd and common_pkg.vhd. Essentially they moved the function declaration from the package to the file where the function is used, which fixed the problem.

Kindly check your email for the workaround. Thanks.

Best Regards,

Ven Ting

Hi Job,

May I know if the workaround is satisfiable?

Let me know if there is any update or other concern on this

[JobvW]

Yes, Thanks!!

So in the problem was that i tried to use a function in a package that gets declared in the same package.

Thank you very much!!
