A soft keepout margin preventsother cells from being placed within the margin, but the cells can be moved in during optimization and legalization. A hard keepout margin never allows other cells within the margin.
一般the cells can be moved in during optimization and legalization指的是哪些cells呢?
还有一个问题一般margin的distance的值设置为多少呢?
为什么放置Blockage能help prevent congestion and DRC errors??
求指导 |
