请教怎么读以下两份报表。第一份如下:
PowerPCB ECO Generator (Version 6.0) 2009-3-10 13:55:06
Copyright (c) 1995-2001 Innoveda, Inc. - All rights reserved
ASCII reading (part types and decals) - 0 msec
ASCII reading (part types and decals) - 10 msec
Reading the Schematic
WARNING: Signal CHGND has 1 pins
There are 53 parts in the design
There are 29 signals in the design
There are 112 pins in the design
ASCII reading (parts, nets, attributes) - 19 msec
Reading the PCB
There are 53 parts in the design
There are 29 signals in the design
There are 113 pins in the design
ASCII reading (parts, nets, attributes) - 21 msec
Final cost=660
Partitioning - 1 msec
Final Matching - 3 msec
Deleted pins: 13, Added pins: 14
我只明白其中一部分。请问msec是什么?
第二份如下:

怎么会出现笑脸?不是我加的,可能是冒号:的缘故。不好意思
没人帮忙看看哦
msec是毫秒
第二个这个是说你的设计存在的问题,网表和PCB的网络不一致,这个不会看不懂吧?
1,R5,Q2,D2,P1在原理图里和PCB里的器件封装信息不一致
2,PCB上比原理图多出了4个网络
3,你在PCB里的网络连接关系和原理图发生了变化。
回复6楼:不是完全懂。是直接在PCB DECAL里面改封装的缘故,应该问题不大哦。
这个你还是注意一下,有时候可能一时的大意,你的设计就出问题了,呵呵
恩,还好,还要评审。毕竟一个人的能力是有限的
