AUTO_ANALYZE_METASTABILITY

Specifies whether synchronization register chains detected with the 'Auto' setting of the Synchronizer Identification option are analyzed for metastability. When this option is disabled, only 'Forced' or 'Forced if Asynchronous' chains are analyzed for metastability. When a synchronization register chain is analyzed for metastability, then its registers are optimized for improved Mean Time Between Failure (MTBF) as long as the Optimize Design for Metastability option is turned on, and the Timing Analyzer reports the metastability MTBF for the chain if it meets the design timing requirements.
