说明：   很多网友渴望自己设计电路原理图（SCH）、电路板（PCB），同时希望从 原始SCH到PCB自动布线、再到成品PCB电路板的设计周期可以缩短到1天以内！ 是不是不可能呢？当然不是，因为现在的EDA软件已经达到了几乎无所不能的 地步！由于电子很着重实践，可以说，不曾亲自设计过PCB电路板的电子工程 师，几乎是不可想象的。
(many netizens are eager to design circuit diagram (SCH), circuit board (PCB), hope from the original SCH to PCB automatic routing, then finished the PCB circuit board design cycle can be shortened to less than a day! Is not impossible? Of course not, because the EDA software has reached a point where almost omnipotent! As electronic very focused, it can be said that they have not personally designed PCB circuit boards of electronic engineers, almost inconceivable.)
