verilog矩阵显示爱心16*16

以下是一个简单的Verilog代码实现，用于在16x16矩阵中显示一个爱心：

module heart_display(
    input wire clk, //时钟信号
    input wire rst, //复位信号
    output reg [15:0] display //16x16矩阵显示输出
);

reg [3:0] row, col; //行和列计数器
reg [15:0] heart [15:0]; //存储爱心图案的数组

initial begin
    //初始化爱心图案
    heart[0] = 16'b0000000000000000;
    heart[1] = 16'b0000000000000000;
    heart[2] = 16'b0000000000000000;
    heart[3] = 16'b0000000000000000;
    heart[4] = 16'b0000000000000000;
    heart[5] = 16'b0000000000000000;
    heart[6] = 16'b0000000000000000;
    heart[7] = 16'b0000000000000000;
    heart[8] = 16'b0000000000000000;
    heart[9] = 16'b0000001110000000;
    heart[10] = 16'b0000011111000000;
    heart[11] = 16'b0000111111100000;
    heart[12] = 16'b0001111111110000;
    heart[13] = 16'b0001111111110000;
    heart[14] = 16'b0000111111100000;
    heart[15] = 16'b0000011111000000;
}

always @(posedge clk or posedge rst) begin
    if (rst) begin
        row <= 0;
        col <= 0;
        display <= 0;
    end else begin
        if (col == 15) begin
            col <= 0;
            row <= (row == 15) ? 0 : row + 1;
        end else begin
            col <= col + 1;
        end
        display <= (heart[row][col] == 1) ? 16'b1111111111111111 : 16'b0000000000000000;
    end
end

endmodule

该代码使用一个16x16的数组存储爱心图案，并通过行和列计数器逐个扫描并在显示输出中显示爱心。当心形数组中的值为1时，显示输出中的对应LED点亮，否则LED熄灭。该模块的时钟信号为`clk`，复位信号为`rst`，显示输出信号为`display`。
