[DRC0003]帮助里没有讲。但你传的内容是两个PORT不一致。
[DRC0004] Possible pin type conflict
管脚冲突：在DRC检查连个输出连接在一起等情况，具体可以选择ERC Matrix tab来设定。如图所示：
A pin type is not compatible with another pin on the same net as specified by the ERC Matrix. (You can set pin types using the ERC Matrix tab on the Design Rules Check dialog box.)
For example, the default settings for the ERC Matrix specify that output pins are incompatible with other output pins. Therefore, this message will appear when two output pins are connected.
0 r8 L8 _; w& @/ [: hThis message also will appear if the pin or hierarchical port on a hierarchical block type is not compatible with a hierarchical port on the same net. Make sure that pins and hierarchical ports use appropriate pin types.

先看看

那么如何修改某一个特定的PIN的DRC错误呢？？
