std_logic
的目的是什么?枚举类型?
'U': uninitialized. This signal hasn't been set yet.
'X': unknown. Impossible to determine this value/result.
'0': logic 0
'1': logic 1
'Z': High Impedance
'W': Weak signal, can't tell if it should be 0 or 1.
'L': Weak signal that should probably go to 0
'H': Weak signal that should probably go to 1
'-': Don't care.
