Allegro导入CIS网表成功，但是placement报错

骑驴找宝马

我copy了一个demo原理图的一页图纸，位号重新编了一下，把demo pcb的封装库也导出来了，并且在我自己的PCB里把库的路径设置好了
$ O" [; k8 x) o' @8 f" K导入网表没有报错，但是就在我quick place时，报error：components could not be placed, logo如下，请问这是什么原因造成的？求指教！

你确定一下你导出的那些封装吧，我以前也是这样的，导出demo的封装，用package designer去看，其实里面根本就没有pin，所以到pcb的时候会报错，一个一个去检查你导出的封装吧

zhouqingmin

demo pcb的叠构和你PCB的叠构名称不同吧

zhuyt05

原理图导出网表时，封装名称默认长度是33，要改成255. 你的封装名称长。

回忆着回忆

你没有画板框吧

woaidashui

如果你确定封装都有的话，那就只有一种可能了，你只设置了PSM路径，没有设置PAD路径。  candence中，如果封装中使用的PAD没有设定路径的话，照样是导不进来的。setup——user preference——Path——padpath和psmpath

freeren

封装都有的话，就只剩路径问题

dzkcool

如果用第一方网表导入的话，没有封装也是可以导入的，只是会出现wraning，而非error罢了，而wraning是不影响正常导入的，所以还是仔细检查一下封装路径(PadPath、PsmPath)是否正确，有无非法字符等。

$ k$ C+ m9 b9 o你说的这些全部没有问题，这些symbol是有的，没有的话，导网表就会报错了，我是从demo中导出来的，
奇怪 ...

那就重新导入一下试试，检查一下你的库的路径有没有特殊字符或者你的symbol里面包含有特殊字符和原理图中的pcb footprint的名字不一致，最好拷贝到excl中比较一下

你的psm path可能没有设置正确，或者你的库路径中没有这几个symbol

' M: y7 F& r, H/ V# {, w. B你说的这些全部没有问题，这些symbol是有的，没有的话，导网表就会报错了，我是从demo中导出来的，
" d' b) Q; |. F0 v6 W奇怪的是这页原理图的所有器件都不能摆放，但是导网表又没有错误
