大家好
我想使用Xilinx的Virtex-4芯片学习VHDL FPGA编程，以便： 1.真正学习贸易（我是初学者，想在真实芯片上进行FPGA编程）。 2.开发我自己的片上系统，这将成为实验设备的一部分（在物理学中） 通过USB接口（在Virtex-4和PC主机之间）从PC主机控制。 我应该为我的目标选择哪些开发工具包？ 我正在阅读有关Xilinx的许多开发套件，这些开发套件与Virtex-4配合使用但有困难 决定为我的工作买哪一个。 你可以，请就此提出建议。 以上来自于谷歌翻译 以下为原文 Hello All I want to learn FPGA programming in VHDL using Virtex-4 chip from Xilinx in order to: 1. learn the trade really (I am a beginner and want to practice in FPGA programming on real chip). 2. develop my own system-on-chip which would be a part of experimental device (in physics) controlled from PC host through USB interface (between Virtex-4 and PC host). What development kit I should choose for my targets? I was reading about many development kits from Xilinx which work with Virtex-4 but have difficulty deciding which one to buy for my work. Could you, please give an advice on this.

我用ML403板。
你可以在这里阅读我的发现：http：//www.fpgafromscratch.comSven 以上来自于谷歌翻译 以下为原文 I use the ML403 board. You can read about my findings here: http://www.fpgafromscratch.com Sven |

谢谢你的建议。
实际上，我在发布之前也在阅读你的博客，并且认为ML403对初学者来说太先进了。 你认为DS-KIT-FX12MM1（Virtex-4 FX12 Mini模块）对于初学者来说是什么？ 以上来自于谷歌翻译 以下为原文 Thank you for advice. Actually, I was reading your blog too before posting and have got an impression that ML403 is too advanced for a beginner. What you think about DS-KIT-FX12MM1(Virtex-4 FX12 Mini module) for a beginner to start from? |

如果你是一个新手，你就不会认为任何FPGA套件是先进的，无论是一个还是其他的.Memec micromodule可能看起来像“小”，但它并不意味着它更少
高级。 MM的缺点是你也绝对需要基础模块。 MM本身没有耗材，并且使用了非标准的标题，所以如果你只获得MM，你就会被卡住。 但是如果你比较ML40x和MMon底板，呃最好得到一些Xilinx制造的KIT，希望你得到更好的支持.Antti Lukats 以上来自于谷歌翻译 以下为原文 there is no such think as "too advance.." if you are a newbie, you must count that any FPGA kit is advanced, be it one or someother. the memec micromodule may look like "small" but it doesnt mean its much less advanced. The drawback with MM is that you ABSOLUTLY need the base module also. The MM itself has no supplies, and used non-standard headers, so if you only get the MM you are instantly stuck. But if you compare the ML40x and MMon baseboard, eh better get some Xilinx made KIT, there is hope that you get better support. Antti Lukats |

当我开始使用ML403板时，我是新手。
我之前从未编程过FPGA。我花了6个月的时间来加快速度，但现在我觉得使用这块板非常舒服。 如果价格不是问题，我认为这是一个不错的选择 以上来自于谷歌翻译 以下为原文 I was a newbie when I started with the ML403 board. I had never programmed an FPGA before. It took me 6 month to get up to speed, but now I feel quite comfortable using this board. If price is not a problem I think it is a good choice. Sven |

好吧，在'太高级'之下，我的意思是它太复杂（而且太昂贵）。
虽然我当然需要一些可自行编程和使用的东西，我想知道：如果我从ML403开始，我可以实现一个通过USB接口从PC主机控制的数字系统吗？我需要开发一个有许多数字电路的系统 脉冲编程器，接收器和滤波器 - 我只想从PC中指定电路的许多参数：脉冲宽度，相位，延迟，带宽等，然后运行电路并在PC屏幕上看到接收器后的信号。大约70000个门就够了，我相信 那我应该选择什么工具包呢？ 以上来自于谷歌翻译 以下为原文 Well, under 'too advanced' I meant that it is too complicated (and too expensive) to start from. Though I certainly need something self sufficient which can be programmed and used and I wonder: If I would start with ML403 could I implement a digital system which is controlled from PC host computer through USB interface? I need to develop a system which has many digital circuits like pulse programmers, receivers and filters - I just want to specify from PC many parameters for the circuits: pulse widths, phases, delays, bandwidths etc, ther run the circuits and see signal after receiver on PC screen.About 70000 gates would be enough, I believe, and what kit I should choose then? |

价格不是一个大问题。
我只是太新手了，害怕我能买到难以管理的东西。我相信你的博客是一个很大的帮助。 我只对我能用ML403做什么感兴趣。 真的，它只是用于设计新的ASIC和编程Virtex-4芯片，还是我可以开发一个片上系统？我需要在PC主机和SoC（片上系统与Virtex-4）之间实现USB接口 它是一个单独的模块（PCB）？ 以上来自于谷歌翻译 以下为原文 Price is a not a big problem. I am just too newbie and afraid that I could buy something which is too difficult to manage.Your blog is a big help, I believe. I am just interested what I could do with ML403. Really, is it only for design of new ASICand programming a Virtex-4 chip or I could develop a system-on-chip with this too? And I will need to implement USB interface between PC-host and SoC (system-on-chip with Virtex-4) should it be a separate module (PCB)? |

使用EDK软件和MicroBlaze或PowerPC处理器，您可以开发任何您喜欢的东西。
您还可以使用Xilinx提供的许多“免费”IP模块 以上来自于谷歌翻译 以下为原文 Using the EDK software and the MicroBlaze or PowerPC processors you could develop anything you like. There is also many "free" IP blocks from Xilinx you can use. Sven |

我推荐使用Spartan-3A入门套件或Spartan-3E 1600E MicroBlaze开发套件。
虽然这些不使用您所询问的Virtex-4部件，但它们的成本要低得多，而且您学习的所有内容都将同样适用于Virtex FPGA，除了一些部件特定的细节，以及嵌入式PowerPC 核心存在于某些Virtex部分。如果您还没有关于VHDL的书籍，我强烈推荐Ashenden的“VHDL设计师指南”。您需要通过USB接口获得多少带宽？ 对于低于8 Mbit / s，我建议使用DLP-USB245M-G或DLP-2232M-G模块作为USB接口。 它们可以从Mouser获得，并提供一个8位并行接口，您可以轻松连接到FPGA，以及主机驱动程序，使其像高速COM端口。 虽然一些评估板确实包含USB接口，但您会发现使用它们相对困难。 以上来自于谷歌翻译 以下为原文 I'd recommend the Spartan-3A Starter Kit, or the Spartan-3E 1600E MicroBlaze Development Kit. Although these don't use the Virtex-4 part you're asking about, they're significantly less expensive, and everything you learn with them will be equally applicable to Virtex FPGAs aside from a few part-specific details, and that embedded PowerPC cores are present in some Virtex parts. If you don't already have a book on VHDL, I highly recommend Ashenden's "Designer's Guide to VHDL". How much bandwidth do you need through the USB interface? For less than 8 Mbit/s, I recommend using a DLP-USB245M-G or DLP-2232M-G module as your USB interface. They are available from Mouser, and provides an 8-bit parallel interface that you can easily connect to the FPGA, and host drivers that make it act like a high speed COM port. Although some evaluation boards do contain USB interfaces, you will find that it is relatively difficult to use them. |

..几乎结束了故事 - 我找到了一家小型俄罗斯公司（www.abnuniversal.ru），它出售来自Xilinx，Altera等的FPGA套件，并且他们在这两个国家都设有办事处 - 在纽约和莫斯科的某个地方。
因此他们的服务对我来说似乎更好 - 我已经订购了Spartan3E 1600E套件，价格为750美元（约合2万卢布），并且他们将在2-3周内交付 - 比官方经销商的承诺更快。 所以我将有两个套件 - 一个来自Altera，另一个来自Xilinx。 这是一件好事，因为我实际上将与我的15年代一起学习FPGA编程。 侄子和我们每个人都会拥有它自己的套件，我们可以对它们进行操作，让我们的思想变得更好！ :) 以上来自于谷歌翻译 以下为原文 ..and nearly end of the story - I have found a small Russian company (www.abnuniversal.ru) which sells FPGA kits from Xilinx, Altera etcand they have offices in the both countries - somewhere in NY and in Moscow. Thus their service seems better for me - I have placed an order on Spartan3E 1600E kit for about 750 USD (~20 thousand roubles) and they will deliver this in 2-3 weeks -faster than official distributor promises. So I will have 2 kits - one from Altera and another from Xilinx. It's a good thing because, I actually will learn FPGA programming together with my 15 y.o. nephew and each of us will have it's own kit and we can even trade them and make our minds which one is better! :) |

我一直对学习FPGA感兴趣，并且想知道为此得到哪个板（我在此之前也发现了Sven的教程）。
无论如何，我正在看digikey提供的开发工具包。 我买不起Virtex电路板，因此我的选择是：HW-SPAR3A-SK-UNI-G - 带有SPARTAN-3A的套件 - $ 225 HW-SPAR3-SK-UNI-G - 套件STARTER SPARTAN-3 - $ 149 HW-SPAR3E-SK-US-G - KIT STARTER SPARTAN-3E - 149美元这些电路板有什么区别？ 3A是最强大的吗？ 我的兴趣主要是DSP，但可能是未来的仪器/控制。 这些套件的软件是否可用于Sven讨论的ISE / EDK？ 以上来自于谷歌翻译 以下为原文 I've been interested in learning FPGA, and have wondered which board to get for this (I also just found Sven's tutorial before coming here). Anyway, I'm looking at the dev kits available at digikey. I can't afford the Virtex boards, so my options are: HW-SPAR3A-SK-UNI-G - KIT STARTER W/SPARTAN-3A - $225 HW-SPAR3-SK-UNI-G - KIT STARTER SPARTAN-3 - $149 HW-SPAR3E-SK-US-G - KIT STARTER SPARTAN-3E - $149 What are the differences between these boards? Is the 3A the most powerful? My interest would be mainly for DSP, but possibly instrumentation/control in the future. Is the software available for these kits the ISE/EDK that Sven discusses? |

S3e套件上的FPGA比它小得多500比S3a板上的700小，S3A的主要区别在于它具有更灵活的多引导功能，用于DSP处理没有太大的区别我订购S3a套件只是因为我想测试多引导的东西以便正常播放
S3e套件可能更好，因为它有非DDR2内存板，内存更容易处理DDR2，s3a套件你的主内存是DDR2，这限制了你的设计，因为S3AAntti的功能DDR2内存控制选项很少 •卢卡兹 以上来自于谷歌翻译 以下为原文 the S3e kit has little smaller FPGA on it 500 vs 700 on S3a boards the main differences for S3A are that it has more flexible multiboot functions for DSP processing there are no big differences I did order S3a kit only because I wanted to test out the multiboot things for normal play the S3e kit may be better as it has non DDR2 memory on board and that memory is easier to handle as DDR2, with s3a kit your main memory is DDR2 and that limits your designs as there are very few options for functional DDR2 memory control for S3A Antti Lukats |
