Web5 feb. 2024 · The most common method used is the two stage synchronizer using flops. The two flops should be placed as close to each other as possible so there is no combinational delay between the flops. This ensures that entire clock cycle is available for the metastability to resolve. There is a possibility that the input will be settled into a wrong ... 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.
