Ten Ways Your Synchronizer MTBF May Be Wrong - SemiWiki

Websynchronizer allows the flip-flops more time to resolve any metastable output. This is statistically equivalent to increasing its resolve time by the clock period minus its propagation delay. MTBF for a two-stage synchronizer is given in equation 2. All ter ms, except for the third one, are the same as in equation 1. WebUse of Data and Synchronizer Flip-Flops Data Flip-Flop Temporary storage of data Prevent data values from corruption during a clock cycle Hold data values for multiple clock cycles Deterministic cycle-to-cycle operation Implies large setup/hold times Synchronizer Flip-Flop Minimize Pr(failure) Data/clock may arrive at any time which may cause a setup/hold greatest hits radio leeds and west yorkshire

Web答案很简单，不可以。原因就是组合逻辑的输出可能会有毛刺，这些毛刺会增大第一级flop产生metastable的概率，进而影响整个synchronizer的MTBF。所以对于任何单bit信号， … http://www.gstitt.ece.ufl.edu/courses/spring17/eel4712/lectures/metastability/cdc_wp.pdf WebDesigners can use special metastable hardened flops for increasing the MTBF. For example, in Figure 4, a synchronizer flop is used following the signal DB. So, instead of the metastable signal DB being used in the function downstream as in Figure 3, the stable signal DB2 is used in the logic downstream.

This formula uses 2 Variables. Variables Used. Probability of Synchronizer Failure - Probability of synchronizer failure is denoted by P (failure) symbol. Acceptable MTBF - Acceptable MTBF is defined as mean time between failures which increases exponentially with cycle time. STEP 1: Convert Input (s) to Base Unit.

WebAdding slack in the synchronizer chain increases the available settling time for a potentially metastable signal, which improves the chance that the signal resolves to a known value, … Web24 apr. 2024 · Unfortunately, designers often mistakenly drive this synchronizer with combinational logic (Figure 2). The result is that the combinational logic will transmit any glitches into the synchronizer, thus reducing the mean time between failure (MTBF) of the synchronizer; and hence the reliability of whole circuit.

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).
