怎么在spartan 3e中实现adc

这是你应该如何进行：
阅读您正在使用的电路板的原理图。
阅读您正在使用的电路板上的ADC数据表
记下您将用于FPGA逻辑和ADC接口的时钟频率
记下需要发送到ADC的控制信号
记下从ADC输入数据，生成时钟等所需的逻辑部分。
然后设置为逐个编写每个逻辑的HDL代码。
逐个模拟每件作品，直到您确信每件作品都按照您的意图运作
将各个部分连接在一起，并模拟您的设计，直到您确信您的设计有效
在板上编程FPGA并测试您的设计
如果您使用的是现成的开发板，则应该向董事会和工具包用户论坛发布更多评论和问题。
祝你好运！

以下为原文

Here's how you should proceed:
 

• Read the schematics of the board you are using.
  
• Read the datasheet of the ADC on the board you are using
  
• Write down what clock frequency you will be using for your FPGA logic and for your ADC interface
  
• Write down what control signals you will need to send to the ADC
  
• Write down the pieces of logic which will be needed to input data from the ADC, generate clocks, etc.
  
• Then set down to write HDL code for each of the pieces of logic, one by one.
  
• Simulate each piece, one by one, until you are confident that each piece works as you intend
  
• Connect the pieces together, and simulate your design, until you are confident your design works
  
• Program the FPGA on the board and test your design
  

If you are using an off-the-shelf development board, you should post further comments and questions to one of the board and kits user forums.
 
Good luck!

先生，我已经在fpga板上编程（即斯巴达3e）。
但我的问题是我将如何在斯巴达3e板上给出模拟信号并观察输出？我正在使用dsp平台（不是edk）和使用micrlaze。
请帮助

sir,i have already programmed on fpga board (i.e spartan 3e). but my question is how will i give analog signal on spartan 3e board and watch the output  in cro?i am working in dsp platform ( not in edk) and using microblaze. plz help

那么，要在板上“给出模拟信号”，你需要一个信号发生器。
大多数实验室都拥有它们，并且可以从许多卖家那里廉价购买。
您还可以使用声卡模拟输出来驱动ADC输入。
至于查看CRO的输出，有些问题：
a）是否还有人使用CRT的工作范围？
我们这里的液晶平板都是关于它的。
b）ADC将数据输入FPGA，因此无论如何都无需查看“示波器”。
----------------------------是的，我这样做是为了谋生。

Well, to "give analog signal on" the board, you need a signal generator. Most labs and have them, and they can be bought inexpensively from many sellers.
 
You could also use a soundcard analog output to drive the ADC input.
 
As for looking at the output on a CRO, some issues:
a) does anyone still have a working 'scope that uses a CRT? We're all about the LCD flat panels here.
b) the ADC brings data INTO the FPGA, so there's nothing to look at on a 'scope anyway.
----------------------------Yes, I do this for a living.

先生，我想用spartan 3e.i连接adc，烧掉了s3e中的代码。
但我想通过函数发生器（即5khz，2伏正弦波）向斯巴达3e板发出信号，并希望将输出视为信号。
但我很困惑，我将如何进行？
你在问如何运行函数发生器吗？
您是否在询问如何将函数发生器输出连接到示波器输入？

sir, i want to interface adc with spartan 3e.i have burnt the code in s3e. but i want to give signal through function generator (i.e 5khz,2volt sine wave) to the spartan 3e board and want to watch the output as signal in cro. but i am confused how will i proceed?
 
Are you asking how to run your function generator?
Are you asking how to connect the function generator output to your oscilloscope input?

抱歉先生，在我无法回答我的问题之前。
我知道我必须使用信号发生器，但在fpga board vina，vinb（来自spartan 3e adc datasheet）输入引脚，我给出信号。
我将探针接触到那个引脚，然后我将在哪里接触fpga板中的接地探针？
我必须在我的adc.vhdl代码中包含microblaze程序以与s3e连接吗？
我不明白先生，你对输出有什么建议。

sorry sir, before i could not represent my questions. i know that i have to use a signal generator,but  in fpga board  vina ,vinb (from spartan 3e adc datasheet) the input pins where i give signals. i touch my probe to that pin,then where will i touch the ground probe in fpga board?
shall i have to include microblaze program in my adc.vhdl code to interface with s3e? i don't understand sir, what have u suggest about output.

我很确定Spartan 3E入门套件有一个相当大的连接器，可以在模拟输入端连接。
该连接器上的一个引脚是GND。
将信号发生器输出接地连接到该点。
MicroBlaze？
我避免使用MicroBlaze和EDK。

I'm pretty sure that the Spartan 3E starter kit has a fairly large connector to which you wire in your analog inputs. One of the pins on that connector is GND. Connect the signal generator output ground to that point.
 
As for MicroBlaze? I avoid MicroBlaze and EDK.

谢谢先生，但是先生，因为我必须显示我的adc输出，我可以使用chipscope pro来监视显示器的输出吗？
如果是这样，可以给我一些链接或提示，我在s3e中如何使用chipscope pro？

thank you sir, but sir as i have to display my adc output, can i use chipscope pro to watch the output in monitor? if so, can plz give me some link or hint, that how i use chipscope pro in s3e?

阅读精细手册，technovlsi！
UG029。
要查找UG029，您应该花些时间学习如何使用Xilinx网站的“搜索”工具。
对于使用Xilinx FPGA的设计人员而言，这是一项宝贵且必不可少的技能。
它将使您更加自给自足，并提供对基本设计信息的更快捷访问。

Read the fine manual, technovlsi!  UG029.
 
To find UG029, you should take some time for learning how to use the 'search' tool for the Xilinx website.  This is a valuable and essential skill for designers using Xilinx FPGAs.  It will make you more self-sufficient, and provide quicker access to essential design information.
