I get a few warnings during linting, and the synthesis does not complete, it does say it is due to lint warnings but there are a handful of the lint warnings I want to share. I have 16GB of memory if that is not enough for synthesis of the design, could be another possibility.

Please send the log file

1-synthesis.log,1-synthesis.warnings,linter.log,1-synthesis.errors

I hope it is related to RAM and swap memory issue, has it got struck at ABC synthesis. Increase your swap memory and try again
