I am getting this log from the tapeout job. I am confused about what change I should make to my layout. The log only gave me a fail message without telling me where was the problem. Can anyone help me?

Where is FAIL message in about log? Are you pointing STDERR?

My project was the same way, and I couldn't figure out from the log why the tapeout didn't pass.

MET density and FOM Density just check it. its shows some warning with error message maybe the cause
