I have the code as below but it failed at compile error.
我有如下代码，但它在编译错误时失败。
typedef struct {
logic [7:0] mem_data[1024];
} mem_blk;
mem_blk m_mem[];
...
...
logic [7:0] data = 'h12;
m_mem[3].mem_data[0] = data;
the error information is : Error- [SV-RTOOBAW] Reference to out of bound array word
错误信息是：错误 - [SV-RTOOBAW]引用超出范围的数组字

Dynamic arrays need to be allocated using new[], or a copy from an array of the same time. So you need to do
需要使用new []分配动态数组，或者同时使用数组中的副本。所以你需要这样做
m_mem = new[4];
Before you can reference m_mem[3].
在你可以参考m_mem之前[3]。
Or maybe you meant to declare an associative array instead of a dynamic array.
或者你可能想要声明一个关联数组而不是动态数组。
mem_blk m_mem[bit [15:0]];
Then a write to m_mem[3] allocates that entry.
然后写入m_mem [3]分配该条目。
