怎么确定计算机上安装了哪些版本的Xilinx工具

我担心你使用“编程”一词。
通常意味着
物理地将比特流从系统传输到硬件。
对于
那个应用程序（Impact软件）你最好只使用最新版本。
使用早期软件生成的比特流对硬件进行编程
版本很好。

以下为原文

I'm concerned about your use of the term "programming."  Usually that means
physically transferring the bitstream from your system to the hardware.  For
that application (Impact software) you're better off just using the latest version.
Programming the hardware using a bitstream generated by earlier software
versions is just fine.

嗨Gabor，
我想我应该使用除编程之外的其他单词。
我正在尝试使用TCL shell自动化Xilinx工具，然后对设备iMPACT批处理文件进行编程。
我实际上并没有尝试直接“编程”设备。
我希望有一个选项可以使用早期版本的工具，即使我也有最新版本，因为我遇到了最新的错误，导致我无法使用该版本。
阁楼

Hi Gabor,
 
I guess I should have used a different word other than programming. I'm trying to automate the Xilinx tools using the TCL shell and then program the device iMPACT batch files. I'm not actually trying to directly "program" the device.
 
I want to have an option to use an earlier version of the tools even if I also have the latest because I have on occassion run into a bug with the latest that prevented me from using that version.

我不认为有一个内置的TCL命令来确定ISE版本。
但由于Xilinx工具版本始终使用XILINX环境变量和PATH env var，因此您只需使用shell命令修改env var并加载您想要的ISE工具版本。



以下为原文

I don't think there's an build-in TCL command to determine the ISE version. 
 
But since Xilinx tool versions always go with the XILINX environment variable and PATH env var, you can simply modify the env var using shell commands and load the the ISE tool version you'd like.

再次感谢您的回复，但我认为您误解了我的问题。
我正在创建一个工具，其他人将使用Xilinx工具自动完成简单的项目创建，综合和编程。
因此，我的目标是找出计算机上安装了哪些版本的Xilinx工具。
同样，此工具的目标是使用计算机上存在的任何版本的Xilinx工具。
因此，我想弄清楚的是版本实际安装在计算机上。
我可以使用类似于http://www.xilinx.com/support/answers/35500.htm所述的类似方法来确定安装的名称和版本号。
该方法假设我知道工具的安装位置。
我可以通过环境变量找出一个版本，但是如果有多个版本我会陷入困境，因为环境变量只告诉我一个版本。
是否有办法确定特定计算机的所有已安装的Xilinx工具版本？

Thanks again for the reply, but I think you've misunderstood my question.
 
I'm creating a tool that other people will use to automate simple project creation, synthesis, and programming with the Xilinx tools. My objective is therefore to figure out which versions of the Xilinx tools are intalled on the computer. Again, the objective for this tool is to work with whatever version or versions of the Xilinx tools are present on the computer.
 
Therefore, what I'm trying to figure out is versions are actually installed on the computer. I can figure out the name and the version number of the installation using a similar approach as described http://www.xilinx.com/support/answers/35500.htm. That approach assumes that I know where the tools are installed. I can figure out one version though the environment variable, but I'm stuck if there are multiple versions since the environment variable only tells me about one version.
 
Is whether there is a way to determine all installed versions of the Xilinx tools for a particular computer?
