Synthesis: Place and route failure for Arria device in Debian 11 platform

[Swetha_A]

The following error is caught for all the features for Arria device during Place and route for 20.1.1 version of Altera.

Error (293007): Current module quartus_fit ended unexpectedly. Verify that you have sufficient memory available to compile your design. You can view disk space and physical RAM requirements on the System and Software Requirements page of the Intel FPGA website (http://dl.altera.com/requirements/).

ERROR: Error(s) found while running an executable. See report file(s) for error message(s). Message log indicates which executable was run last.

RAM specification of debian 11 machine was 10GB while max peak virtual memory occupied in the session was 3GB.

Attached the place and route, matlab command window log and device RAM specification

The same features were running fine in debian 10 machines.

What is the Required RAM specification for deb 11 and 20.1.1 version?

Do we have any effects in debian 11 machine?

If the same features were running fine in debian 10 machines, then debian 11 machine should be not much problem because both required almost the same RAM specification. What i can suggest is to delete db and db_incremental files and recompile again. Make sure other not used applications are closed. If the problem still persists, you may have to increase virtual memory.

Any further update or concern?

Thank you sir,

The problem persists even after deleting db and db_incremental folders.

I'm debugging the issue more and will acknowledge once I get any solution.

Hi,

If like that you may have to increase the memory RAM or reduce the design size. Place and route usually consumes more RAM during compilation. 

Best regards,

Sheng

The issue was not reproducible using machines with higher RAM memory but the issue got fixed after updating the swap space to non-zero in 10 GB RAM debian 11 machines. The place and route was failing due to zero swap space in debian 11 machines.

It has taken time for us to debug and identify the actual cause. 

Thank you for the patience!

Just know about there is such feature for extra RAM space. Great to know that. Thanks for your genuine sharing. May be you can mark it as solution for better future reference.
