是否有计划放弃ISE？

G，
ISE 14.7是最后一次构建。
它是，并将完全支持，必要的偶尔补丁（对于任何出现的错误）。
它旨在为28nm节点之前的所有产品（以及ISE中已经支持的28nm器件）提供支持。
展望未来，ISE 14.7将会存在很长一段时间，因为我们仍然有许多以前的技术节点正在生产中。
如果代工厂不再支持某个节点（例如几年前已经发生在旧的250nm节点上的情况），那么我们会发出一年的警告，一年之后再过一年的最后一次购买机会
。
你是一个伟大的公司，因为有ISE的主导软件。
它将会出现，直到28nm器件停产。
28nm节点可能成为业界运行时间最长的节点之一，因为它已经非常受欢迎。
从现在起十年后我就不会看到ISE被使用了。
由于Vivado仅支持从28nm节点开始的设备，因此在Vivado拥有与ISE一样多的用户之前还需要一段时间。
即便如此，所有改进和新功能都只会出现在Vivado中。
ISE未计划在14.7之后进行任何改造（重新发布）。

g,
 
ISE 14.7 is the last build.  It is, and will be fully supported, with the necessary occasional patches (for any bugs that show up).
 
It is intended to provide support for all the products before the 28nm node (as well as the already supported 28nm devices in ISE).
 
Moving forward, ISE 14.7 will be around for a very long time, as we still have many of the previous technology nodes in production.
 
If a foundry can no longer support a node (such as what has already happened to the older 250nm node a few years back), then we issue a one year warning, followed a year later by a one year period for the last time buy opportunities.
 
You are in great company, as the dominant software out there is ISE.  And it will be around until the 28nm devices go out of production.  The 28nm node may become one of the longest running in the industry, just because it has been so immensely popular.  I would not be surpprosed to see ISE being used ten years from now...
 
Since Vivado only supports devices starting with the 28nm node, it will be awhile yet before Vivado has as many users as ISE.  Even so, all the improvements and new features will only appear in Vivado.  ISE is not scheduled for any revamp (re-issues) after 14.7.

显而易见的问题是ISE永远不会在Windows 8和后续操作系统上运行，所以虽然微软仍然支持Win7，但在某些时候你将无法购买安装了它的新机器。
这是一个严重的问题，人们希望Xilinx不会将其吹走。

The obvious issue is that ISE will never run on Windows 8 and follow-on operating systems, so while Win7 is still supported by Microsoft, at some point you won't be able to buy a new machine with it installed. 
 
This is a serious issue, and one hopes that Xilinx isn't blowing it off.

That's what I do on my MacBook Pro. 
 
Cue complaints from students about having to spend $80 on VMWare and another $200 on Win7 ... 
----------------------------Yes, I do this for a living.

我的看法......
1. Vivado不支持Spartan-6设备。
这是批量设备系列，用于生产和开发工作。
这是Xilinx保持ISE良好支持的强大商业激励。
2. ISE工具集的稳定性和熟悉性是Xilinx的宝贵资产，而非负债。
ISE有助于提高品牌忠诚度（或超过）设备成本或设备性能。
放弃ISE或迫使忠诚的Xilinx客户迁移到新的工具集，将导致Xilinx失去一些客户和/或业务。
Xilinx拥有强大的商业利益，能够尽可能降低Xilinx客户的“障碍”。
2.a向第7代（及更高版本）设备的迁移受到了学习新技术和新工具集的要求的阻碍。
如果我可以使用相同的ISE工具集，我会更倾向于考虑第7代设备，我在这个工具集上需要相当多的投资来理解和支持。
到目前为止，我还不需要Gen 7设备专门提供的任何功能，这使我决定坚持使用ISE（和第6代）。
2.b拒绝向ISE添加Windows 8支持会向当前和新的Xilinx客户发送错误消息。
没有Windows 8，您无法轻松购买新的台式机或笔记本电脑，大公司的大多数设计工程师都无法选择操作系统。
Xilinx不是在真空或泡沫中运行，Xilinx的客户也不是 - 新机器的当前主流计算平台是Windows 8，而不是Windows 7。
2.c为ISE添加Windows 8支持将使ISE的生命周期延长3年。
这是一个明智的做法。
2.d迫使客户在Xilinx ISE工具集和Windows 8之间进行选择是一个错误。
这不能很好地结束。

以下为原文

My take...
 
1.  Vivado does not support Spartan-6 devices.  This is the volume device family, both for production and for development work.  This is a strong business incentive for Xilinx to keep ISE well-supported.
 
2.  The stability and familiarity of the ISE toolset is a valuable asset for Xilinx, not a liability.  ISE contributes to brand loyalty as much as (or more than) device cost or device performance.  Abandoning ISE, or compelling loyal Xilinx customers to migrate to a new toolset, will result in Xilinx losing some customers and/or business.  Xilinx has a strong business interest in keeping the 'hurdle' to remain a Xilinx customer as low as possible.
 
2.a  Migration to Gen 7 (and later) devices has been hindered by the requirement to learn both a new technology and a new toolset.  I would be much more inclined to consider Gen 7 devices if I could use the same ISE toolset with which I have a considerable investment in understanding and support.  So far, I have not needed any features offered exclusively by Gen 7 devices, and this makes the decision to stick with ISE (and Gen 6) a no-brainer, for me.
 
2.b  Refusing to add Windows 8 support to ISE sends the wrong message to current and new Xilinx customers.  You cannot easily buy a new desktop or laptop machine without Windows 8, and most design engineers in large companies do not have a choice of operating system.  Xilinx does not operate in a vacuum or bubble, nor do Xilinx' customers -- the current mainstream computing platform for new machines is Windows 8, not Windows 7.
 
2.c  Adding Windows 8 support to ISE will extend the lifetime of ISE for another 3 years.  This is a no-brainer.
 
2.d  Forcing customers to choose between Xilinx ISE toolset and Windows 8 is a mistake.  This cannot end well.

No, this is arguably a very bad idea.  This implies both new design target technology as well as a new toolset.  Any experienced design engineer understands the value of making as few concurrent changes -- and introducing as few new risks to a project -- as possible.
 
It is responsible and prudent to stick with the technologies and tools with which you are familiar, if you know they can get the job done for you.
 
Just to put a fine point on this -- if ISE works well and is well understood, and it supports the devices you wish to use -- what is the 'value added' by switching from ISE to Vivado (or any other FPGA design toolset, for that matter)?

如果一个人在现有部件上开始新设计，那么使用Vivado的附加值就是学习Vivado，因为它是从你的第一条评论中得到的（我非常同意）。
而不是等待设计必须使用ISE不支持的部分，因此人们将被迫使用Vivado，这将是一场双重斗争。
但如果一个人很了解一个部分，那么学习Vivado会相对容易一些。

If one is starting a new design on an existing part, the value added of using Vivado is learning Vivado as it follows from your first comment (with which I strongly agree). Instead of waiting for a design where one has to use a part which is not supported by ISE so one will be forced to use Vivado so it will be a double struggle. But if one knows a part well, learning Vivado on it would be relatively easier. It even may make sense to have a dual track on a smallish project to push it through both toolsets.
The bottom line is new chips will not work with Vivado and if one wants to be able to use them Vivado is a must. Planning how to get there is good strategy for any engineer.

Austin,
 
Thanks for the updates and the feedback.  It is good to hear from Xilinx people sometimes to reaffirm the faith a little!

G，
正如我之前所说，很多时候，我们是一个成功的企业，因为我们真正关心我们正在做什么（提供）。
每位Xilinx员工都对我们的技术和产品（软件，硬件，IP，工具和支持）感到自豪，并始终致力于成为最佳人选。
其中一部分是拥有卓越的客户沟通和支持的传统。
没有人要求我这样做，但我现在已经是Xilinx监察员超过15年了。
我跟随彼得·阿尔克克（Peter Alfke）开辟的道路，他“永远是一名工程师，从不让营销工作妨碍解决问题。”
我执行这项任务是因为它对成功是绝对必要的（以我的拙见）。
我不能每天花费超过几分钟，因为我没有收到任何“信用”。
营销“看起来是另一种方式”，我们同意“参与规则”。
我们都需要很好的技术营销才能生存和发展，但必须以某种方式提供工程“诚实”。
毕竟，营销幻灯片并不销售优质产品：（数十万）工程师的辛勤工作对此负责。
我感谢任何好评。
当人们诚实，并愿意与我们合作解决他们的问题并改进时，我也很感激。
如果有人有问题，问题或想法如何让事情变得更好，请告诉我。
我很可能无法解决它，但我会知道谁可以。
Austin Lesea主要工程师Xilinx San Jose



以下为原文

g,
 
As I have said before, many times, we are a successful business because we actually care about what we are doing (providing).  Every Xilinx employee is proud of our technology, and our products (software, hardware, IP, tools, and support) and always strives to be the best they can be.
 
Part of that is having a tradition of excellent customer communication and support.
 
No one asks me to do it, but I have been a Xilinx ombudsman for more than 15 years now.  I was following in the path blazed by Peter Alfke, who "always an engineer, never let marketing get in the way of solving problems."  I perform this task because it is absolutely essential to success (in my humble opinion).  I cannot spend more than a few minutes on it a day, as I receive no 'credit' for it.  Marketing "looks the other way" and we do agree on the "rules of engagement."
 
We all need great technical marketing to survive and thrive, but one has to supply the engineering 'honesty' somehow.  After all, marketing slides don't sell great products:  the hard work of  (tens of) thousands of engineers are responsible for that.
 
I appreciate any nice comments.
 
I also appreciate when people are honest, and willing to work with us to solve their problems, and improve.
 
If anyone has an issue, problem, or an idea how to make things better, let me know.  I will most probably not be able to solve it, but I will know who can.

嗯，这就是事情。
我们使用Spartan 3AN设备作为“软糖”FPGA。
由于我们是一家小公司，因此我们倾向于使用少量设备来解决许多项目。
虽然200AN对于某些东西来说可能太大了，但如果我们用托盘而不是更小的数量购买它们，它对我们有利。
我们也有400AN库存。
当我们需要BRAM或SERDES时，我们使用Spartan 6。
我认为我们不再使用V4了。
如果概述中列出的小型设备实际可用，那么迁移到Artix将非常引人注目！
XC7A20和35设备在哪里？我注意到2013年7月29日的最新版本的Series 7 Overview DS180，v1.14甚至不再列出v1.13概述中的非“T”Artix7设备
2012年11月！
Checkfindchips.com为什么分发。
只列出100和200个设备，其他设备不存在，只有100个设备实际有库存，每个200美元！
XC3SD1800A的价格为每片75美元。
XC6SLX16也可以30美元的价格广泛使用。这里的比较指标是切片的数量，这是不完整的.S3A和S6没有PCIe端点块和GTP，但对于许多应用它们并不是必需的。我意识到这一点
不是Artix和S6或S3A之间的1：1比较，但我认为你看到了我的观点。
我认为很多客户都会以同样的方式看待7系列设备：整条生产线上根本没有满足我们需求的设备，我们认为未来几年不会发生变化。
弃用客户使用的软件毫无意义。
如果我们必须学习一个新的工具集（实际上比你相信的一些呜呜声更痛苦，眨眼眨眼），“其他人”也提供满足我们需求的设备。
此外，他们的工具在最新的操作系统上运行时没有问题。
（记录：我认为Windows 8是一场灾难，这是一个普遍的看法。我还没有看到8.1;办公室里没有人有一台运行它的机器。戴尔和任何人仍然会销售带有Windows 7的机器 -
64安装，但问题是多久。）
----------------------------是的，我这样做是为了谋生。

Well, here's the thing. We use the Spartan 3AN devices as "jellybean" FPGAs. Since we are a small company, it works in our favor to settle on a small handful of devices to use across many projects. While the 200AN might be too big for some things, if we buy them in trays instead of smaller quanities, it works in our favor. We stock the 400AN, too. We use Spartan 6 when we need the BRAMs or the SERDES. I don't think we'll use V4 any more.
 
Migrating to Artix would be compelling if the small devices listed in the overview were actually available! Where are the XC7A20 and 35 devices? I notice that the most recent version of the Series 7 Overview DS180, v1.14 dated  29 July 2013 no longer even lists the non-"T" Artix7 devices which are in the v1.13 overview from November 2012! 
 
Check findchips.com for what's in distribution. Only the 100 and 200 devices are listed, the others don't exist, and only a few of the 100s are actually in stock and they're $200 each! The XC3SD1800A is widely available for $75 each. The XC6SLX16 is also widely available for $30. The comparison metric here is number of slices, which is admittedly incomplete. The S3A and S6 don't have PCIe endpoint blocks and the GTPs but for many applications they're not necessary. I realize that this is not a 1:1 comparison between Artix and S6 or S3A but I think you see my point. 
 
I think that a lot of customers look at the Series 7 devices in the same way I do: there are simply no devices in the entire line which meet our needs, and we don't see that changing in the next couple of years. Deprecating the software which your customers use makes no sense. If we have to learn a new toolset (which is actually less painful than some whingers would have you believe, wink wink), the "other guys" offer devices which meet our needs, too. Plus their tools don't have issues running on the newest operating system.
 
(For the record: I think that Windows 8 is a disaster, and that's a common opinion. I haven't seen 8.1 yet; nobody in the office has a machine which runs it. Dell and whomever will still sell machines with Windows 7-64 installed, but the question is for how long.)
