set_power_options -dynamic true -low_power_placement true。low_power_placement该如何理解,看不明白man想表达啥意思
就是尽量减少功耗, 设成true吧,
具体你可以做个试验, 改成false,出来比较下,report_power ,

这条命令现在新版本已经不支持了,我想问一下,这条命令对power的优化会很明显吗?
改成set_prects_power_optimization_options 了
optimize_prects_opt_power
可能是用到multiVt cell? 比如非critical path的地方会用HVT cell来placement
