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 users are eager to design the circuit schematic (SCH), circuit board (PCB), also expressed the hope that from the original automatic SCH to PCB routing, and then finished circuit board PCB design cycle can be shortened to less than 1 day! It is not impossible? Of course not, because the EDA software has now reached the point where almost anything! As a very focused practice, it can be said that has not been personally designed PCB circuit boards, electronic engineers, is almost unimaginable.
