我调用元件的时候操作方法一样,但只有BANK7 AND BANK8 没有报错,其余几个都报错了.$ u7 h' M' [0 J
还有就是我在多页原理图中使用分层端口符号,结果报错:5 D! p3 A) s2 @

我是在一个电路图上设置端口为output,另一个图上则为input,结果就产生上面的错误,改成一致的就没问题了,但我不明白的是,从原理上说不是一个input,一个output才连接正常吗?为什么都是input或output才可以?我看网上下载的原理图也是一个input,一个output?2 M! H, x- H) s& X# H. `' w7 W

请教大家怎么修改啊.谢谢了 * e4 l2 O0 v: t( ~1 Y9 @) c5 ?; C a# M0 q( v4 [' B

上传个原理图看一下!作者: elmma 时间: 2008-3-2 15:50
上传的原理图,.我现在把端口都改成一样的
