阅读手册或用户指南。
你读过手册了吗？
你能找到手册吗？2。
搜索论坛（并搜索网页）以寻找类似的主题。
不要在多个论坛上发布相同的问题。
不要在别人的主题上发布新主题或问题，开始新的主题！5。
学生：复制代码与学习设计不同.6“它不起作用”不是一个可以回答的问题。
提供有用的详细信息（请与网页，数据表链接）.7。
您的代码中的评论不需要支付额外费用。
我没有支付论坛帖子的费用。
如果我写一篇好文章，那么我一无所获。

Summary:
1. Read the manual or user guide.  Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts.  If I write a good post, then I have been good for nothing.

我现在添加了第317行作为评论。



以下为原文

I added line number 317 as a comment now.

你没有推断任何东西。
你正在实例化。
请保持这一点，因为这不是一个微不足道的区别。
无论如何，真正的问题是你根本不应该使用这些属性。
通用映射应该有一个名为DATA_WIDTH_A的条目，您应该使用该条目而不是属性。
----------------------------是的，我这样做是为了谋生。



以下为原文

You're not inferring anything. You are instantiating. Please keep this straight, as it is not a trivial distinction.
 
Anyways, the real problem is that you should NOT use those attributes at all.
The generic map should have an entry called DATA_WIDTH_A which you should use instead of the attribute.
 
----------------------------Yes, I do this for a living.

嗨，谢谢你的回复。
这是真的......它不是属性，它是通用的...... 
这可以在“库指南”中轻松看到。
问候，

Hi and thank's for your reply.
It's true... it's not an attribute, it's generic...
This can easily be seen in the Libraries Guide .

嗨，谢谢（APOSTROPHE FAIL！）的回复。

您将VHDL属性与列出的“属性”混淆，因为可以通过通用映射修改泛型来控制这些属性。
不要犯这个错误。
回到Bad Old Days，库原语不支持通用映射构造，用于控制如何构建所述原语的实例。
在某些时候，工具允许通用映射，并且有一段时间，通用映射和VHDL属性都被接受（并且在具有两者的代码中，通用映射具有优先权）。
现在，VHDL属性已被弃用，有利于使用通用映射。
删除属性，正确设置通用地图，您的设计应该继续。
----------------------------是的，我这样做是为了谋生。

You're confusing VHDL attributes with the "attribute" listed as something that can be controlled by modifying the generic through the generic map. Do not make this mistake.
 
Back in the Bad Old Days, the library primitives did not support the generic map construct for controlling how an instance of said primitive was built. At some point, the tools allowed generic maps, and for a while, generic maps and the VHDL attributes were both accepted (and in code that had both, the generic map had precedence).
 
VHDL attributes are now pretty much deprecated in favor of using generic maps. Delete the attributes, set the generic map correctly, and your design should go forward.

嗨贝斯曼59，
确实如此。
我读了*属性*而没有进一步思考我想到了经典的vhdl属性。

Hi bassman59,
 
that's true. I read *attribute* and without thinking further I thougt about classic vhdl attributes. :-/
