还有就是我在多页原理图中使用分层端口符号，结果报错： & @/ Y5 S. w. H7 oERROR [DRC0003] Port has a type which is inconsistent with other ports on the net DRAM_CKE: SCHEMATIC1, EP2C20 BANK1 AND BANK2 (2.70, 4.80) ! m Z' Q8 u3 \) k$ p) {
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?' @+ q, y+ `: [; g) h

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
