Hold margin
Nettet那么,遇到hold violation一般怎么修呢? 根据上面的公式可以看出,主要有三类方法: 1. 增大data line delay 此方法为后端设计中最常见的手法。 具体操作是在data line上插入buffer 或者delay cell去增加delay。 在此提出一个问题请大家思考:插入buffer或者delay cell的位置,是靠近launch端还是capture端,还是并无任何要求呢? 答案下期揭晓~ 2. 增 … Nettet15. nov. 2012 · Re: how to decide setup and hold margin on state timing anal Well, 10% is not a magic number. I use 15% most of the time. Also, use aggressive wireload model in your early synthesis can take some wiring delay into the synthesis consideration, which will make post-layout timing closure somewhat easier.
