The default initial value for a variable with scalar type T is T'LEFT, or the left-most value in the range of T. The default initial value for a variable with type STD_LOGIC is U, which corresponds to STD_LOGIC'LEFT. The default initial value for a variable with composite type is the assignment of the appropriate default initial value to each of the variable's subelements. |
ACTION: To avoid receiving this message in the future, assign a value to the variable prior to its use. In particular, look for If Statements or Case Statements that may create paths where a variable retains its default initial value. You can also assign an appropriate initial value to the variable in its Variable Declaration.
