各位数字大神们，求助。谢谢了

我写了一个8051的顶层例化程序。但是DC老是报错。程序如下：module module_top_1( input wb_rst_i_pad,input wb_clk_i_pad,input wbi_ack_i_pad,input wbi_err_i_pad,

错误提示如下：
谢谢各位大神了。

图片没传上来啊

不好意思，图片没有上传成功。不过问题已经解决了，谢谢大家。问题就是我在例化oc8051这个module的时候，有很多端口还没有定义。所以系统就默认为是1位的，但是我在例化PAD的时候，又generate了8位或者16位的，因此报错。定义oc8051后，就没有出现错误了。
