添加新源ip core generator后进程映射失败

嗨各自的成员，
我是这个环境中的新手，使用ise设计套件8.2.1i和virtex 4 lx60。我正在使用基于智能卡黑盒子的设计。
目前我正在尝试替换源文件 - 但保留实际的名称文件，以便不需要从顶层设计进行修改。
之前的源文件是使用较旧的.coe文件从核心生成器 - 单端口块内存构建的。
我替换了最新的.coe文件并重新生成它，并在项目导航器中的流程设计中添加.xco文件。
核心生成器和.coe文件中生成的所有文件都包含在项目文件夹中。
进程映射时出现问题。
错误发生如下： -

你能否告诉我这个错误的原因是什么，请告诉我删除错误的步骤？
请提前帮助和感谢。非常感谢所有的努力。

Hi respective members,

Im newbie in this environment using ise design suite 8.2.1i and virtex 4 lx60.Im working with a design based on smart card black box.

Currently im trying to replace source file - but keeping the actual name file so that no modification need to do from the top design. The previous source file was built from core generator-single port block memory using older .coe file. Im replaced the latest .coe file and regenerate it and add the .xco file in the flow design in project navigator. All the generated file from core generator and .coe file are included in the project folder.



the problem occured at process mapping. The error occured as below :-
