近来发觉,timing-setup中的环境变量设定set_IO_latency,在各资料中的设置有些不同,
有人支持,也有反对的建议

Set IO Clock Latency
Timer will attempt to create 0 clock skew for the I/O ports by automatically choosing a clock arrival time at the port that is equal to the worst of the fanout of the port.
不是很明白!
有哪位大侠能给我指点迷津?

就是cts之后 把cts 的latency完全标在IO上,
取最大的latency值,和反标virtual clock latency一样,
就是不用人工来反标,比较方便,
这样做对嘛?
看来,我得悬赏了
