ASIC中同步复位与异步复位

xuduo6845

在大规模ASIC中，同步复位是不是应该行CTS那样做复位树的？异步复位需不需要呢？为什么？

sync reset 基本上把它當一般的Timing Path 即可, 不需做 tree.
google " sync async reset " 會得到很詳細的說明

synchronus reset with simple respected clock.it is required more no of gates,and it is didnt have metastabilty problem.it is working is slow.
