用verilog写一个数据位宽为512bit的axi_full读写接口

以下是一个数据位宽为512bit的AXI Full读写接口的Verilog代码示例：

module axi_full_interface(
  input wire clk,
  input wire resetn,
  input wire [31:0] awaddr,
  input wire [7:0] awlen,
  input wire [2:0] awsize,
  input wire [1:0] awburst,
  input wire awvalid,
  output reg awready,
  input wire [511:0] wdata,
  input wire [63:0] wstrb,
  input wire wlast,
  input wire wvalid,
  output reg wready,
  output reg [31:0] bresp,
  output reg bvalid,
  input wire bready,
  input wire [31:0] araddr,
  input wire [7:0] arlen,
  input wire [2:0] arsize,
  input wire [1:0] arburst,
  input wire arvalid,
  output reg arready,
  output reg [511:0] rdata,
  output reg [1:0] rresp,
  output reg rlast,
  output reg rvalid,
  input wire rready
);

  reg [31:0] addr;
  reg [63:0] data;
  reg [31:0] len;
  reg [2:0] size;
  reg [1:0] burst;
  reg valid;
  reg [1:0] resp;
  reg last;

  // Address write channel interface
  assign awready = (addr == awaddr) && (len == awlen) && (size == awsize) && (burst == awburst) && (valid == awvalid);
  always @(posedge clk) begin
    if (resetn == 1'b0) begin
      addr <= '0;
      size <= '0;
      burst <= '0;

    end
    else if (awready && awvalid) begin
      addr <= awaddr;
      size <= awsize;
      burst <= awburst;

      len <= awlen;
    end
  end

  // Write data channel interface
  assign wready = (addr == awaddr) && (valid == 1'b1);
  always @(posedge clk) begin
    if (resetn == 1'b0) begin
      data <= '0;
    end
    else if (wready && wvalid) begin

    end
  end

  // Response write channel interface
  always @(posedge clk) begin

      valid <= 1'b0;
    end
    else if (bready && bvalid) begin
      resp <= bresp;
      valid <= 1'b0;
    end
    else if (awready && awvalid) begin
      resp <= '0;
      valid <= 1'b1;
    end
  end

  // Address read channel interface
  assign arready = (addr == araddr) && (len == arlen) && (size == arsize) && (burst == arburst) && (valid == arvalid);
  always @(posedge clk) begin
    if (resetn == 1'b0) begin
      addr <= '0;
      size <= '0;
      burst <= '0;
      valid <= 1'b0;
      len <= '0;
    end
    else if (arready && arvalid) begin
      addr <= araddr;
      size <= arsize;
      burst <= arburst;
      valid <= 1'b1;
      len <= arlen;
    end
  end

  // Read data channel interface
  assign rready = (addr == araddr) && (valid == 1'b1);
  always @(posedge clk) begin
    if (resetn == 1'b0) begin
      rdata <= '0;
      rlast <= 1'b0;
      resp <= '0;
    end
    else if (rready && rvalid) begin
      rdata <= data;
      rlast <= last;
      resp <= rresp;
    end
  end

  // Response read channel interface
  always @(posedge clk) begin
    if (resetn == 1'b0) begin
      rvalid <= 1'b0;
      last <= 1'b0;
      resp <= '0;
      valid <= 1'b0;
    end
    else if (valid && rready) begin
      rvalid <= 1'b1;
      last <= 1'b1;
      valid <= 1'b0;
    end
