上述代码改成可综合代码

上述代码已经是针对硬件描述语言(HDL),如Verilog的标准结构,可以直接用于FPGA或ASIC的芯片级设计。但是如果你想将其转换成可直接给Synthesizer(综合器)使用的代码,可以去除注释和非实际的仿真指令(如 `$display` 和 `while` 循环),因为这些在综合过程中通常会被忽略。
下面是简化后的可综合版本:
```verilog
module axi_read (
input wire [31:0] s_axi_aclk,
input wire [31:0] s_axi_araddr,
input wire s_axi_arvalid,
output wire s_axi_arready,
input wire s_axi_rvalid,
output wire [31:0] s_axi_rdata,
output reg [1:0] s_axi_rresp
);
// Drive Address valid
always @(posedge s_axi_aclk) begin
if (s_axi_arvalid) begin
s_axi_araddr = addr;
s_axi_arready <= 0;
end else begin
s_axi_arready <= 1; // Allow next address request
end
end
// Wait for response
always @(posedge s_axi_aclk or negedge s_axi_arready) begin
if (!s_axi_arready && s_axi_rvalid) begin
s_axi_arready <= 1; // Ready for next request after receiving response
s_axi_araddr <= 0;
s_axi_rready <= 1;
end
end
// Read data and check response
always @(posedge s_axi_aclk) begin
if (s_axi_rvalid) begin
s_axi_rdata = s_axi_rdata;
s_axi_rresp = s_axi_rresp;
s_axi_rready <= 0;
if (s_axi_rresp != 0) begin
// Error handling - comment out in synthesis-ready code
// $display ("Error AXI RRESP not equal 0");
end
end
end
endmodule
```
