8通道ADC和FPGA之间的接口如何编码

Asalam ...
ADC不是完全相同的。
适用于一个ADC的接口不适用于不同的ADC。
建议您指定您正在使用的ADC。
这是定制电路板或购买开发板的设计吗？
如果您使用的是购买的开发板，则可能需要下载示例代码。
当然，您需要知道您正在使用哪个开发板，因为所有开发板（如ADC）不一定相同。
问候，

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。

ADCs are NOT all alike.  An interface which works well for one ADC will not work well for a different ADC.  Suggest you specify which ADC you are using.
 
Is this a design for a custom circuit board, or for a purchased development board?  If you are using a purchased development board, it is likely that example code is available for download.  Of course, you would need to know which development board you are using, as all development boards (like ADCs) are not necessarily identical.

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.

asalam写道：
要用FPGA开发8通道ADC接口，我必须编写一个代码来连接这两个接口。
所以对于这个我发现一些pdf文件像Xapp485，xapp774等我已经研究过了。
这很好，为了编写代码，我需要一些参考文档或链接，它们显示了一个relatd接口示例，所以它对我有帮助。
或者通过提供类似的文档（任何pdf）来指导我，甚至告诉我如何以适当有效的方式对其进行编码（vhdl）。
请指导我..........
关心asalam。
您需要的唯一文档是您正在使用的特定ADC的数据表。
该文档将描述控制ADC并为您提供数据的信号的时序。
然后，设计逻辑会产生读出ADC所需的时序，这是一个简单的问题。
当然，一旦你将这些数据输入FPGA，你需要弄清楚如何处理这些数据......
----------------------------是的，我这样做是为了谋生。

To develop an 8-channel ADC interface with a FPGA, i has to write a code for interfacing those two. So for this i found some of the pdf file's like Xapp485,xapp774 etc and i have studied it. that's fine inorder to write the code, i need some referenced documents or links which shows an relatd interfacing example, so that it will be helpful to me. Or guide me by giving similar documets(any pdf) which even tells how to code(vhdl) it in a proper efficient way.
 
 
Please guide me..........
 
 Regards asalam.

The only document you need is the data sheet for the particular ADC you're using. That document will describe the timing of the signals that control the ADC and give you the data. Then it's a simple matter of designing the logic that generates the timing necessary to read out the ADC. Of course you need to figure out what to do with those data once you've got them into the FPGA ...
 
----------------------------Yes, I do this for a living.

tudied ads5282 ADC，我必须在FPGA中实现反序列化（xapp485）模块，以连接到（8通道）ADC。
谁能帮我。



以下为原文

tudied ads5282 ADC, i have to   Implement a de-serialisation(xapp485) block in the FPGA to interface to the (8-channel)ADC.
 
 
can anyone help me.

非常坦率的。
TI的数据表具有为其设计BFM所需的一切。
您可能希望首先设计FPGA逻辑的行为模型，以确保接口正常工作，然后设计可合成版本。
一周以上的经验丰富的工程师不会。
------------------------------------------“如果它不起作用
模拟，它不会在板上工作。“



以下为原文

Fairly straightforward. TI's datasheet has everything you need to design a BFM for it. You might want to design a behavioural model of the FPGA logic first to ensure the interface works properly, then design the synthesizable version. Wouldn't take an experienced engineer above a week.
