用qickplace摆放元器件发现一个没放进去？

提示：WARNING: Could not fit symbol:  X4 / CRYSTAL_DX2-100C_32.768KHZ / DX2-100C

这是怎么回事?用手动放的话，放上去就消失了

打开封装DX2-100C，看不出有什么不对的地方，

PS：这个封装我是用files/exports\libraries从别人的PCB来直接生的

忽然发现原理图里改器件是2只脚的，而封装里是3只引脚的，怎么办呢?

怎么办呢?

产生网表的时候是不是有描述此symbol的txt文件产生?

三个网络表里的对此元件的描述如下：

pstchip.dat
primitive 'CRYSTAL4/SM_0_X4-0705_48MHZ';
  pin
    '1':
      PIN_NUMBER='(1)';
      PINUSE='UNSPEC';
    '2':
      PIN_NUMBER='(2)';
      PINUSE='UNSPEC';
    '3':
      PIN_NUMBER='(3)';
      PINUSE='UNSPEC';
    '4':
      PIN_NUMBER='(4)';
      PINUSE='UNSPEC';
  end_pin;
  body
    PART_NAME='CRYSTAL4/SM_0';
    JEDEC_TYPE='X4-0705';
    VALUE='48MHz';
  end_body;
end_primitive;

pstxprt.dat

  PART_NAME
    X4 'CRYSTAL_DX2-100C_32.768KHZ':;

 
pstxnet.dat

NODE_NAME X4 1
 '@asd.SCHEMATIC1(SCH_1):INS17300732@DISCRETE.CRYSTAL.NORMAL(CHIPS)':
 '1':;

NODE_NAME X4 2
 '@asd.SCHEMATIC1(SCH_1):INS17300732@DISCRETE.CRYSTAL.NORMAL(CHIPS)':
 '2':;

封装文件：dx2-100c.txt的内容如下

(DEVICE FILE: DX2-100C)

PACKAGE 'DX2-100C'
CLASS IC
PINCOUNT 3

PINORDER 'DX2-100C' 3 2 1
FUNCTION G1 'DX2-100C' 3 2 1

END

to：Rtiger_lp

你说的是上面这些内容吗?

只要確定你要用的實際元件是幾只腳就可以了

1.實際元件---3只腳,那將Orcad中的2只改爲3只即OK

2.實際元件---2只腳,那麽就是你用錯封裝了，就要查一下SPEC，看看到底是怎樣，然後修改Decal

pstchip.dat 文件里是这样的：（上面的弄错了）

primitive 'CRYSTAL_DX2-100C_32.768KHZ';
  pin
    '1':
      PIN_NUMBER='(1)';
      PINUSE='UNSPEC';
    '2':
      PIN_NUMBER='(2)';
      PINUSE='UNSPEC';
  end_pin;
  body
    PART_NAME='CRYSTAL';
    JEDEC_TYPE='dx2-100c';
    VALUE='32.768KHz';
  end_body;
end_primitive;
END.

嗯，就是这个文件和device不对应造成的。

sch里认为是2pin，pcb里是3pin.

按照8楼的想法修改sch或者pcb应该就ok了

谢谢各位的指导，因为是抄板子，已经有原理图和PCB文件，看他们给的就是这样，SCH里是2个pin，PCB里是3个PIN，不知道他们怎么给画出来的，浪费了我一个下午，实在不想再浪费时间，就把SCH里的改成了3个pin，－－－OK了

allegro真烂，要是protel早就报错了，它却居然给我来个隐身

呵呵，有些格式的网表是没有symbol里面几个pin的信息的，所以导网表不会有错误，找到symbol就ok

最快解决问题的方法最好，像这样不挺好，别想那么多，哈哈

过来学习学习
