  1. changing a, b, r to std_logic also returns error.
  2. Only boolean <= STD_ULOGIC_VECTOR ?= STD_ULOGIC_VECTOR compiles without error; all of the following combination returns error:
    1. STD_LOGIC <= STD_LOGIC_VECTOR ?= STD_LOGIC_VECTOR
    2. STD_ULOGIC <= STD_LOGIC_VECTOR ?= STD_LOGIC_VECTOR
    3. boolean <= STD_LOGIC_VECTOR ?= STD_LOGIC_VECTOR
    4. STD_LOGIC <= STD_ULOGIC_VECTOR ?= STD_ULOGIC_VECTOR
    5. STD_ULOGIC <= STD_ULOGIC_VECTOR ?= STD_ULOGIC_VECTOR
