OPTIMIZE_FOR_METASTABILITY

This setting improves the reliability of the design by increasing its Mean Time Between Failures (MTBF). When this setting is enabled, the Fitter will aim to increase the output setup slacks of synchronizer registers in the design, which can exponentially increase the design MTBF. This option takes effect only if the Timing Analyzer is being used for timing-driven compilation. Use the Timing Analyzer's report_metastability command to review the synchronizers detected in your design and to produce MTBF estimates.
