The phrase occurs again at line 60 (Mephistopheles reminds Faustus to "Write it in manner of a deed of gift," presumably as opposed to the manner of a contract), and again at line 90 (Faustus calls the completed document "A deed of gift of body and of soul," though he shrewdly goes on to include "conditions").

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。
