pi power integrity 中文意思是什麼
pi power integrity
解釋
電源完整性-
More and more high - switch - rate and high - pin - density devices have been applied to the digital system along with the fast development of manufacture technics of integrate circuit ( up to 65nm ), while the supply voltage of electronic system shows itself a fallen trend ( from 5v to 1. 2v ), signal integrity ( si ), power integrity ( pi ) and electromagnetic compatibility ( emc ) problems have become increasingly serious
具體體現到高速pcb板級設計上,則為信號完整性( signalintegrity ,簡稱si ) 、電源完整性( powerintegrity ,簡稱pi )和電磁兼容性( electromagneticcompatibility ,簡稱emc )問題的影響已經達到了不可忽略的地步,經常會出現邏輯功能正確的數字系統不能在物理結構上實現。
