Design Space Explorer segmentation violation

[gbassi]

Hi all,

recently I am experiencing a segmentation violation error when trying to compile a Quartus project with the DSE. The single compilation is completed correctly by Quartus, from Analysis&Syntheses to Timing Analysis. However when I launch DSE locally, requiring 10 different compilations, Quartus quits unexpectedly reporting the following error:

Has anyone encountered a similar issue?

The things that I have tried so far but unsuccessfully are:

• deleting db and incremental_db folders
• reducing the number of compilations
• allowing only 1 compilation at a time

Unfortunately I cannot update Quartus to a newer version.

Thank you

Hi,

Can you try running DSE using command line ?

Thanks

Dear @KhaiChein_Y_Intel ,

thanks a lot for your answer.

Running DSE using command line works!

Do you know if there is an explanation for this behavior?

I am asking because the same problem may affect other components/processes in Quartus.

Thank you

Best regards,

Giovanni

Hi Giovanni,

Generally, bugs are fixed in the newer version of the software. Since you could not upgrade the design to the latest version, v20.1 to verify if this is fixed in the software, you may use command line as a workaround for v18.1

Thanks

Best regards,
