关于综合的问题

wangping

各位高手：有个问题想请教大家！　我的一个类似双端口ＲＡＭ的一个程序　但是只作为一个通道使用，开辟的空间是１６位的　大小为４Ｋ　分为２块　ＭＥＭ０［１５：８］　ＭＥＭ１［７：０］编译没有错误　但是综合时也没有报告错误！只不过是一直在哪里综合　没有综合成功　也不显示错误！请求高手指点米！！！！万分感激　这个是报告

这个警告信息好象是说txinterface0723.v文件里第73行的 addrout所定义的长度跟 23行的不一致，你自己检查一下？

另外，为什么不用IP核呢？RAM我用的都是ISE里面的IP核。

这个好像是因为 内部的 连线不够引起的 [em03]

不能MEM[15:8]这样定义.必须是MEM[15:0]
