Xilinx声称UCF文件端口不存在

嘿，我正在使用带有Xilinx XC3S500E Spartan-3E FPGA芯片的Spartan 3E - 入门板。
当我在UCF文件中定义我的约束（直接来自用户手册）时，我会收到板上不存在的站点的错误。
但是，我验证了手册，以及我放在文件中的电路板。
配置设置为：xc3s500e-5ft256.我不知道为什么xilinx没有识别配置，但任何帮助将不胜感激，谢谢 - Jon

Hey,

I'm using a Spartan 3E - Starter Board with a Xilinx XC3S500E Spartan-3E FPGA chip. When I define my constraints in the UCF file, which is straight from the user manual, i receive errors for non-existant sites on the board. However, i verified the manual, and the board with what i put in the file. The configuration is set as: xc3s500e-5ft256.

I'm not sure why xilinx isn't recognizing the configuration but any help would be appreciated, thanks
- Jon

乔恩，
更多信息会有所帮助。
请告诉我们您正在使用的ISE版本，错误消息的副本（包括IO引脚询问）以及UCF约束的示例。
谢谢，
大卫

Jon, A little more information would be helpful. Please let us know what version of ISE you are using, a copy of the error message (including the IO pin(s) in question), and a sample of your UCF constraint. Thanks,David
