allegro做dbcheck时出错，不知道怎么回事？

这个flash我其他的板子上面也有用到没有报错，到了这个板子就报错了，不知道是什么原因呢?请高手赐教啊！

ERROR IN SHAPE (1.100 -1.505)
  class = ETCH
  subclass = TOP
  Part of Symbol Def FC1224W2234.
      Which is part of a padstack as a FLASH symbol.
  SHAPE boundary may not cross itself.
  Error cannot be fixed.
ERROR IN SHAPE (-0.910 1.700)

我知道原因了，是板子的精度设置比这颗器件的精度小了，这个板子设了3位，我那颗零件死四位
