When metastability occurs the clock-to-out time can be extended beyond the register's nominal tCO time. The additional time beyond the tCO time for the output signal to settle to a known state is known as the settling time. The tMET of a synchronization register chain is the sum of all output slacks of the registers in the chain.

对于这段话，我的理解是： tMET 时间和 tCO 时间之和就是异步时钟域的亚稳态时间，如果这个时间大于目的时钟域的同步寄存器链的时序余量（大概是时钟周期减去它的建立时间和保持时间之和吧），那么这时候系统采到的信号一定是亚稳态。
