23.15.1 读取压缩的数据	$readmemb and $readmemh are extended to unpacked arrays of packed data, associative arrays of packed data, and dynamic arrays of packed data. In such cases, the system tasks treat each packed element as the vector equivalent and perform the normal operation. When working with associative arrays, indexes must be of integral types.
23.15.2 读取两态类型	$readmemb and $readmemh are extended to packed data of 2-state type, such as int or enumerated types. For 2-state integer types, reading proceeds the same as for conventional Verilog reg types (e.g. integer), with the exception that X or Z data is converted to 0. For enumerated types, the file data represents the ordinal value of the enumerated type. (See Section 3.10) If an enumeration ordinal is out of range for a given type, then an error shall be issued and no further reading shall take place.
