有大神能帮我解释下这两个变量设置的意思和意义吗?The physopt_area_critical_range variable specifies a margin of slack for cells
during area optimization. If a cell has a slack less than the area critical range,
area optimization is not done for the cell. The default value is minus infinity;
that is, all cells are optimized for area during area recovery.
physopt_power_critical_range:This variable specifies a power critical range,
which is a margin of slack for cells
during leakage power optimization. If a cell has a slack less than the power
critical range, leakage power optimization is not performed for the cell.
我看手册里讲的看不大明白,这两个变量怎么用啊?用在什么阶段?
另外area recovery是什么操作,什么意思哦? |
