set_ load命令帮助DC在综合时遵从驱动单元的最大电容设计规则,但该命令并没有为驱动单元的扇出提供独立的约束。在输出端口使用set_ fanout_ load命令时,我们可以为输出端口建立额外的预期扇出负载模型,综合时DC同时也会使内部驱动单元的最大扇出遵守设计规则的要求。 可以使用下面命令reportconstraint -allviolators查看是...
因为cell delay和input transition以及output load有关。当input transition变小时,cell delay也会变小。为了防止修复max_transition而导致hold出现violation,可以设置hold margin。当timing path的裕量大于hold margin时,PT才会修复max transition violation。 set_max_fanout:set_max_fanout 16 [all_outputs]:扇出数直接...
set_max_fanout设置一个节点的最大扇出值。注意这里的值不是值扇出数目,而是扇出负载的值。 例如,set_max_fanout 6 [get_ports IN] get_attribute INV1/A fanout_load // if 0.25 get_attribute INV2/A fano...

这个列表基本上就是用户的时间轴。我们会加入他自己帖子的ID,以及其关注者创建的帖子。基本上我们实现了一个展开写(fanout)。 身份验证(Authentication) 好了,我们或多或少已经有了关于用户的一切,除了身份验证。我们会用一种简单而又健壮的方式处理身份验证:我们不想使用PHP的会话机制,我们的系统要能被轻松地分布式...
set_data_check -from A_IN -to C_IN -setup 2.0 In the above example, A_IN is the related pin and C_IN is the constrained pin. The above constraint would do a setup check of C_IN with respect to A_IN. The data at C_IN should arrive 2.0 ns prior to the edge of A_IN. ...
