verilog16进制转BCD

在Verilog中，将16进制数转换为BCD码的代码如下：

module hex_to_bcd(
    input \[15:0\] hex,
    output reg \[11:0\] bcd
);

reg \[3:0\] i;
reg \[6:0\] hex_temp;

always @(hex) begin
    hex_temp\[6:0\] <= hex\[10:4\];
    bcd <= 12'b0;
    
    for (i = 0; i < 6; i = i + 1) begin
        bcd <= {bcd\[10:0\], hex_temp\[6\]};
        
        if (bcd\[3:0\] > 4'd4)
            bcd\[3:0\] <= bcd\[3:0\] + 4'd3;
        
        if (bcd\[7:4\] > 4'd4)
            bcd\[7:4\] <= bcd\[7:4\] + 4'd3;
        
        if (bcd\[11:8\] > 4'd4)
            bcd\[11:8\] <= bcd\[11:8\] + 4'd3;
        
        hex_temp <= hex_temp << 1;
        bcd <= {bcd\[10:0\], hex_temp\[6\]};
    end
end

endmodule

这个模块将输入的16进制数转换为BCD码，并输出到`bcd`信号中。
