verilog 代码
下面是一个简单的Verilog RAM拼接代码示例:
```verilog
module ram_concatenation (
input clk,
input [7:0] addr1,
input [7:0] addr2,
input [7:0] data_in1,
input [7:0] data_in2,
input write_en,
output [7:0] data_out1,
output [7:0] data_out2
);
reg [7:0] ram1 [255:0];
reg [7:0] ram2 [255:0];
assign data_out1 = (write_en) ? {ram1[addr1], data_in1} : ram1[addr1];
assign data_out2 = (write_en) ? {ram2[addr2], data_in2} : ram2[addr2];
always @(posedge clk) begin
if (write_en) begin
ram1[addr1] <= data_in1;
ram2[addr2] <= data_in2;
end
end
endmodule
```
这个示例代码包含两个256字节的RAM,每个RAM有8位宽度。它们通过地址线共享,但是数据输入和输出是分开的。当write_en信号为高电平时,数据将被写入到RAM中。当write_en信号为低电平时,RAM将从指定地址读取数据,并将其输出到data_out1和data_out2端口。
