Hi,

If the log file does not show anything, the error is probably occurring during the Quartus compilation. You can run the compiler with "-v" option and see if it is happening after the first stage compilation.

There are a few possibilities. If your design is close to full, it is possible that your design is simply not fitting or routing. Please check the resource estimation given by the compiler. Although it happens rarely, quartus may be failing due to a bug or simply may run out of memory if your design is big and the machine you are using does not have large amounts of memory. I think at least 8-16 GB is recommended for Quartus.
