3.4. Reducing Metastability Effects

You can check your design's metastability MTBF in the Metastability Summary report, and determine an acceptable target MTBF given the context of your entire system and the fact that MTBF calculations are statistical estimates. A high metastability MTBF (such as hundreds or thousands of years between metastability failures) indicates a more robust design.

This section provides guidelines to ensure complete and accurate metastability analysis, and some suggestions to follow if the Intel® Quartus® Prime metastability reports calculate an unacceptable MTBF value. The Timing Optimization Advisor (available from the Tools menu) gives similar suggestions in the Metastability Optimization section.
