对原理图所有元器件重新命名的时候，需要执行Tool->Annotate命令，于是就出现了这个错误：
Cannot perform annotation of heterogeneous part 'U?A(Value MT48LC4M32B2)', part has not been uniquely grouped (using a common User Property with differing Values) or the device designation has not been chosen
Done updating part references
不知道怎么回事，请高手解答！
