You enabled or disabled the following Design Assistant rules: but at least one of the rules contains an illegal value

Due to a change in the Quartus II software version 13.0, you may see this error if your Quartus II Settings File (.qsf) enabled Design Assitant checking for rules M101, M102, M103, M104, or M105. Starting with the Quartus II software version 13.0, Design Assistant only runs post-synthesis or post-fitting. Rules M101, M102, M103, M104, and M105 for state machine checking were only used when running Design Assistant post-elaboration and are no longer supported.

To avoid this error, remove any assignments for Design Assistant rules M101, M102, M103, M104, or M105 from your .qsf.
