network具有传输型。 Set_dont_touch (已经被set_dont_touch_network -no_propagate代替)忽略,port,cell,design,pin上的优化(timing optimization),但是不会忽略DRC。network具有传输型 这样我们在综合的时候就要对high fanout net做一定的约束,让dc不对这些net做优化以及加入buffer。下面分三种情况来说明。 1.Clock,...

We have a reset synchronizer with very high final fanout. The synchronized reset signal typically ties to the R, or sometimes the P, input of the destination FFs. Due of the high fanout and wide distribution (anywhere in the SLR) of the reset signal, t
