innovus工具get_clocks命令报出来的时钟会重复,因为工具报的是2个analysis view下的clock name,如下图: 方法2:get_db clocks。innovus工具get_db clocks命令报出来的时钟也会重复,重复的原因也是有两个analysis_view,如下图: 解决办法:可以指定一个view来报clock,方法如下: 参见知识星球。 在PR走线时,我们需要指...

get_pin_info Replace with the actual name of the clock pin obtained in the previous step. Step 11: Analyze Source Clock The "get_pin_info"command will provide details such as the clock source, clock tree, input frequency, and any derived clocks from the source. Analyze this information...
All the optimization decisions are based on true propagated clocks and account for clock gates, inter-clock paths, and on-chip variation (OCV) derates. A new FlexH feature in the implementation system provides a structure that is topologically as close to an H-tree as possible, with ...
