用sv写一个带有存储功能的模块，且该模块需要拥有axi从机接口

我可以回答这个问题。使用SystemVerilog编写一个带有存储功能的模块，需要定义一个存储器模块，然后在主模块中实例化该存储器模块，并将其连接到AXI从机接口。在存储器模块中，可以使用Verilog中的$readmemh和$writememh指令来读取和写入存储器中的数据。同时，需要定义一个存储器地址寄存器和数据寄存器，用于存储读取和写入操作的地址和数据。在主模块中，需要定义一个状态机来控制存储器的读写操作。

该模块包含四个主要的处理器，以支持AXI读写数据和outstanding计数：

- `axi_read_address_handler`：根据outstanding计数和AXI读取地址的有效性，控制ARREADY信号，以指示AXI主机是否可以发送下一个读取请求。
- `axi_write_address_handler`：根据outstanding计数和AXI写入地址、数据和有效性，控制AWREADY信号，以指示AXI主机是否可以发送下一个写入请求。
- `axi_write_data_handler`：根据outstanding计数和AXI写入数据的有效性，控制WREADY信号，以指示AXI主机是否可以发送下一个写入数据。
- `axi_read_data_handler`：根据outstanding计数和AXI读取数据的有效性，控制RVALID、RLAST、RRESP和RDATA信号，以指示AXI主机是否可以读取下一个数据。

此外，该模块还包含一个简单的数据RAM，用于存储AXI写入的数据。数据RAM的大小为1024个32位字，每个字都可以通过地址线axi_awaddr[9:2]来访问。

该模块包含一个AXI4从设备状态机和一个简单的内存接口。当从设备接收到读请求时，它将等待地址阶段完成，然后开始数据阶段，并将读取的数据保存在数据寄存器中。一旦数据阶段完成，从设备将等待响应阶段完成，并将读取的数据和响应发送回主设备。内存接口支持读写操作，并使用了$mem_read和$mem_write系统任务。
