Orcad网表到PADsPCB的转换问题

从上面，可以看出PowerPCB5.0导入Orcad网表时，用Padspcb.dll或Pads2k.dll的并没差别；

PadsLogic输出的网表格式：

Part Reference PartType@Part Decals

如：U1 R@0402

如果令PartType与Part Decals有一样的名称,并在PCB Foorprint一栏中添加：@{PCB Footprint}

则创建的网表就有与PADsLogic一样的形式；

如果PartType与Part Decals的名称不一样，可以在原理图的元件属性中添加PartType的属性栏并赋予相应的值，PCB Foorprint一栏中输入{PartType}@{PCB Footprint} 就可以。

/////////////////////////////////////Attention//////////////////////////////////

原理图中元件的属性栏，有Source Package属性，这栏实际上相当于PADs中的PartType，

所以创建网络表时就可以在PCB Footprint中输入：{Source Package}@{PCB Footprint}

最后Pads-PCB建库时，PartType的名称可以与Source Package一样，同个PartType对应不同的Decals，如：

.

R136 R@0402

R137 R@0603

R138 R@0805

.

.

.

C19 C@0603

C20 C@0805

.

.

Q1 Q@TO-92

Q2 Q@SOT-23

.

X1   XTAL@XTAL/S

X2 XTAL@XTAL/U

X3 XTAL@XTAL/3X8

X4 XTAL@XTAL/2X6

X5 XTAL@XTAL/SMD50X32

X6 XTAL@XTAL/SMD70X50

X7 XTAL@OSC4

.

.

U11 S-35390A@S0P8

U12 S-35390A@TSSOP8

.

导入时的一些错误：

1

Reading file -- D:\Work station\....\PADS2000.asc
*Unspecified or unsupported version of ASCII file
*PADS2000*

Can't find part Type item < BATTERY >
BAT1 BATTERY@BATTERY_SD_10MM

*Bad *PART* ascii data line format
C1 CAP NP@0603

显然是PCB封装库中没有名称为BATTERY和CAP NP的PartType。

2

Reading file -- D:\Work station\....\PADS2000.asc
*Unspecified or unsupported version of ASCII file
*PADS2000*

*Not valid pin name for part type CATHODE

LED5.CATHODE U15.18

*Not valid pin name for part type ANODE

RN23.1 LED5.ANODE

Warning: deleting signal LED0
Warning: deleting signal N362907
**INPUT WARNINGS FOUND**

可能是因为LED5元件的引脚没有PinNumber，

此种情况还可能是因为原理图中用字母形式的PinNumber，而PCB中的PartType中没有给相应引脚分配相应的字母形式的PinNumber

说明元件已经存在，这样原理图添加新的元件时，PCB导入新生成的网表不会覆盖掉已布局好的元件，

下面就是原理图增加了R8和R9，导入到PCB时的提示信息，对已存在的R1～R7报错，并没有对R8和R9报错，并且也没有打乱掉原来的元件PCB布局!!
