MIN_MTBF_REQUIREMENT

Specifies the minimum acceptable Mean Time Between Failures (MTBF), either globally for the design or for a specific synchronizer chain (if applied to the head register of a synchronizer chain). The MTBF value used will be 10 to the power of this setting value, in years. If the MTBF of a synchronizer chain is less than this value, it will be marked as a dangerous, asynchronous transfer that is in need of additional synchronization registers to help avoid metastability.
