生成网表说管脚定义重复，怎么办？

我是新手，正在做我的第一个电路图，有个很简单的问题，不知怎么解决。

费了几个小时把208脚的FPGA的和FLASH的的符号造好了，把每个管脚加了名字。当然还有电源和EEPROM等小东西，然后大体连了线（主要是先检查一下）。把浮动的线用Place net alias给了名字。

然后做个“Annotate”和“生成网表”，检查以下，看看能不能过。

Annotate没有太多的反馈，只是更新了参考名字而已。

可是网表就很多错误，结果是没有一个对的地方。主要的问题是说管脚定义的重名。可是很多脚就是一个名，我能怎么办呢?多谢指导。

能不能把你这张图发给我看看,QQ:185878963,加我,在告诉你邮箱

allegro的netlist不能有相同的管脚名
除了power

你在做零件的過程，可以先將VCC或VSS設成Power Pin，這樣了，既使都叫VCC也不會有問題…
但是如果是I/O, 建議你乖乖的給它名字，要不然它可是不會讓你轉Netlists的。
