As developing tissues grow in size and undergo morphogenetic changes, their material properties may be altered. Such changes result from tension dynamics at cell contacts or cellular jamming. Yet, in many cases, the cellular mechanisms controlling the ph
延迟单元。常用于datapath,相比较与buffer,可以添加更多的delay,用来修复hold timing。 6、buffer cell 作用同delay cell,用来增加延时。相比较于delay cell,驱动能力更强,但是添加的delay更小。因此大的slack可以使用delay cell,较小的用buffer cell。 7、corner cell ...
