使用Spartan 3E代替Spartan 3A运行isetut有哪些变化？

嗨，
当我在上一章“影响教程” - 第7章 -  UG695（第12.3节）2010年9月21日出现错误时，我正在执行ise教程。
本教程是为Spartan 3A / 3AN系列和XC3S700A套件准备的。但是，我有一个Spartan 3E / XC3S500E套件。
当我执行第138页的步骤1到3时，我遇到了这种不同之处，因为出现了一个警告对话框，告诉您：“描述xc3s700a的BIT文件即将被分配给以前标识为xc3s500e的设备。
你确定要这样做吗？“
在此消息之后，没有像教程推荐的那样有效。
为此，我与教程（从vhdl开始）保持一致。
为了解决这个问题，我回到了设计项目并改变了
我所拥有的家庭和设备。
在此之后，我确实运行了“合成 -  XST”过程，没有任何问题。
但是，当我确实运行“实施设计”过程时，我得到了（带有
毫不奇怪）map子进程的问题。
错误消息是：
“将设计映射到LUT ...错误：MapLib：30  -  clk上的LOC约束E12无效：设备上没有此类站点。要绕过此错误，请设置环境变量'XIL_MAP_LOCWARN'.ERROR：MapLib：30  -  LOC约束T16

我的问题是：1）是否有任何优秀且耐心的Xilinx专家有兴趣适应（使用PDF-XChange Viewer注释编写）我之前提到过的教程，专门用于Spartan3E / XCS500E？
2）同一个人可以提供任何特定的附加“.bit，.msc，。*”文件，这些文件包含不同的wtut_vhd默认文件，并认为必须继续使用我的系列/设备套件吗？
3）如果必要的更改只是设置新的和不同的引脚（第106到108页的步骤1到9），请忽略问题（1）和（2）并告诉我什么是新的引脚分配（以及我的手册）
可以进一步
信息）。
提前谢谢！安德烈



以下为原文

Hi,
   I was executing the ise tutorial when I got an error in the last chapter,
the "Impact Tutorial" - chapter 7  - UG695 (v 12.3) September 21, 2010.

   This tutorial is prepared for a Spartan 3A/3AN family and a XC3S700A kit.
But, I have a Spartan 3E/XC3S500E kit.

   This diference was presented to me when I was executing the steps 1 to 3
of page 138, because a warning dialog box was presented telling the following:
"A BIT file describing an xc3s700a is about to be assigned to a device
previously identified as an xc3s500e. Are you sure you want to do this?".

   After this message nothing worked like the tutorial was recommending.
   Befor this I was aligned with the tutorial (beginning with vhdl).
   
   Trying to solve the problem, I returned to the design project and changed
the family and the device for the ones I had.
After this I did run the "synthesise - XST" process without
problems. But when I did run the "Implement Design" process, I got (with
no surprise) problems with the map subprocess. The error messages were:
"Mapping design into LUTs...

   device. To bypass this error set the environment variable 'XIL_MAP_LOCWARN'."

   My questions are:
   1) Is there any good and patient Xilinx specialist interested to adapt (writing
with PDF-XChange Viewer notes) the tutorial I mentioned previously to specifically
work with Spartan3E/XCS500E?
   2) Can this same person supply any specific additional ".bit, .msc, .*" files which
are different of the wtut_vhd default files and considered necessary to have to
proceed with my Family/Device kit?
   3) If the necessary changes are only to set new and different pins
(steps 1 to 9 of pages 106 to 108), please disregards questions (1) and (2) and just
tell me what are the new pin assignments (and what manual I can get further
information).

Thank you in advance!
