3.2.1. Metastability Reports

Metastability reports summarize the results of the metastability analysis. In addition to the MTBF Summary and Synchronizer Summary reports, the Timing Analyzer tool reports additional statistics for each synchronizer chain.

If the design uses only the Auto Synchronizer Identification setting, the reports list likely synchronizers but do not report MTBF. To obtain an MTBF for each register chain you must force identification of synchronization registers.

If the synchronizer chain does not meet its timing requirements, the reports list identified synchronizers but do not report MTBF. To obtain MTBF calculations, ensure that the design is constrained correctly, and that the synchronizer meets its timing requirements.
