OPA659的PCB封装

Other Parts Discussed in Thread: OPA659

直接下载了OPA659的PCB封装,用ultra librarian 导入到cadence allegro 16.6里面了,但是想要放置到板子上的时候会报错:

E- (SPMHGE-82): Pin numbers do not match between symbol and component. Run dev_check on device file for more information.

我看了下,allegro里面认为它有是一个引脚

Name: DRB8_1P75X1P5
Type: Symbol Definition

Units: Mils
Accuracy: 2

Pins: 11

我自己也看到的确除了8个引脚之外,中间还有一个散热焊盘,焊盘上也还有两个引脚,的确是11个

但是我不太明白焊盘上的两个引脚是做什么用的?是需要接地的吗?焊盘本身不就是接地的吗为什么还要多两个引脚在上面呢?

同时尝试修改了原理图中的symbol引脚数目,但是无论是9个还是11个,均会报同样的错误,因此想问一下应该怎么解决呢?

麻烦了
