在使用QUARTUSII中遇到的问题

在使用QUARTUS II编译时出现如下错误，编译无法进行下去
Warning: Can't find design file none
Info: Smart recompilation skipped module Analysis & Synthesis because it is not required
Info: Smart recompilation skipped module Fitter because it is not required
Info: Smart recompilation skipped module Assembler because it is not required
Info: Smart recompilation skipped module Timing Analyzer because it is not required
Info: Quartus II Full Compilation was successful. 0 errors, 1 warning

虽然可以先进行语法编译，再进行全局编译可以使编译进行下去，但是这个错误仍然存在。
说一下，我是在使用了signal tap II时，加了个观察信号，然后重新编译，就变成这样了，不知道该怎样解决
谁帮我分析一下好吗，谢谢了

signal tap 2我还没用过哪
