Vhdl UCF文件创建中的错误？

使用EDK创建Microbalze在使用以太网在spartan 6上创建一个简单的Microbalze后，在同一目录的data文件夹中创建一个ucf文件，ddr3 IPS i打开ucf文件：

正如您所看到的，当使用sdk编译并在硬件上启动时，比特流是生成的，在fpga上编程的，而且所有示例都可以正常工作，但是当DDR3的位置不在ucf文件中时，如何正常工作？

我不知道microblaze/edk设置的具体情况，但我知道当我将coregen用于其他组件时（dcms）等其他ucf文件是为这些组件创建的。例如，如果我转到project_dir/ipcore_dir/我将看到我创建的每个coregen模块的一个单独的ucf文件。在您的项目目录中可能有一些其他定义文件（因为基于其他帖子）
