I am running Vivado on a Linux platform and have a project with a space in the project name. In Vivado 2015.2, I was able to synthesize and implement the project without issue.
However, in Vivado 2015.3, the synthesis process launches but then nothing further happens. The status shows that it is running.
The issue is that the full path to the run directory in the runme.sh script is not protected by quotes. This causes the script to fail and exit without launching the run.
This issue exists on the Linux OS version of Vivado 2015.3 only and has been fixed in Vivado 2015.4.
