In my chip, it have 8 digital power pairs, 3 analog power pairs.
when doing mask design, in order ot reduce noise,
1, 8 digital power rail is connected together?
2, 3 analog power rail is connected together?
3, should decouple each power pair each other?
someone could give me detailed discription? thanks!
1) I think that digital power rail must be separated from analog power rail;
2) IO power rail must de separated from core power rail;
3) different analog power rail must be separated from each other.
