Hi All,
As we all know the most suggested method to avoid Metastabilty whenever there is a clock domain switching for a signal is Double synchronising. But so far i am not able to understand how does it really help ? I mean , yes as per the equation the MTBF gets reduced due to double buffering. But apart from the equation i dont see anything which is really convincing. I mean how does double synchronisatin reduces the possibility of Metastability condition itself ??
Can anybody put more light on this ??
Thanks in advance.
