Web平均故障間隔（英語： Mean time between failures ，縮寫：MTBF）是可靠度工程及製造工程學的名詞，意即是產品在操作使用或測試期間的平均連續無故障時間，需要注意的是，這裡探討的MTBF並非一個實測值，而是在產品設計階段工程師依據理論所估算出的參考值。但是仍有例外，例如在文獻所探討的 ...

WebFor Vivado, we must specify that the synchronizer registers should be placed close together (see: UG912), and to show up as part of MTBF reports. For Quartus, specify that these register must not be optimized (e.g. moved into the input register of a DSP or BRAM) and to mark them as composing a synchronizer (and so be placed close together). WebSynchronizers play a key role in multi-clock domain systems on chip. Designing reliable synchronizers requires estimating and evaluating synchronizer parameters τ (resolution time constant) and T w (metastability window). Typically, evaluation of these parameters has been done by empirical rules of thumb or simple circuit simulations to ensure that the … if a is a 2 × 2 matrix then a × i and i × a

http://www.pldworld.com/_altera/html/tip/wp-01082-quartus-ii-metastability.pdf WebMTBF is a basic measure of a system's reliability; the higher the MTBF, the higher the reliability of a product. This relationship is illustrated in the equation: Reliability = e- (time/MTBF). There are a few variations of MTBF you may encounter. They are mean time between system aborts (MTBSA), mean time between critical failures (MTBCF) and ...

Web29 sept. 2009 · The t MET for a synchronizer is the sum of the output timing slacks for each register in the chain. The overall design MTBF can be determined by the MTBF of each synchronizer. The failure rate for a synchronizer is 1/MTBF, and the failure rate for the entire design is calculated by adding the failure rates for each synchronizer, as follows: WebSynchronizer Data Toggle Rate in MTBF Calculation. The MTBF calculations assume the data being synchronized is switching at a toggle rate of 12.5% of the source clock frequency. That is, the arriving data is assumed to switch once every eight source clock cycles.
