基本上我试图通过按住按钮在 basys 3 板上依次打开 led 0 到 led 15

如何解决基本上我试图通过按住按钮在 basys 3 板上依次打开 led 0 到 led 15

module Subtask_A(
    input CLOCK,input BTNC,output reg [15:0]led
    );
    wire clock0p168;
    reg [24:0]SET_COUNT = 8400000; //0.168s
    reg [3:0]counter = 4'b0000;
    wire BTNC_PULSE;
Clock_0p168 clk1 (CLOCK,SET_COUNT,clock0p168);
Singlepulse dev1 (BTNC,CLOCK,BTNC_PULSE);
always @ (posedge clock0p168) begin
    if (BTNC_PULSE == 1) begin
        led[counter] <= 1;
        counter <= counter + 1;
        end
    end
endmodule

module Singlepulse(
    input BTNC,input CLOCK,output pulse
    );
    wire Q1;
    wire Q2;
    reg[25:0] SET_COUNT2 = 16666666;
    wire slow_clock;
    clock_singlepulse clk1 (CLOCK,SET_COUNT2,slow_clock);
    
    D_flipflop dev1 (slow_clock,BTNC,Q1);
    D_flipflop dev2 (slow_clock,Q1,Q2);
    
    assign pulse = Q1;
endmodule

module D_flipflop(
    input CLOCK,input D,output reg Q,input NRESET
    );
    
    always @ (posedge CLOCK or negedge NRESET) begin
        if (! NRESET)
            Q <= 0;
        else
            Q <= D;
     end
endmodule

module Clock_0p168(
input CLOCK,input [23:0] SET_COUNT,//number of bits must change accordingly    
output reg set_freq = 0
);
reg [23:0] COUNT = 0;
always @( posedge CLOCK ) begin
COUNT = COUNT + 1;
set_freq <= ( COUNT == SET_COUNT )? ~set_freq: set_freq;
COUNT <= ( COUNT == SET_COUNT )? 0: COUNT;
end
endmodule

module clock_singlepulse(
input CLOCK,input [25:0] SET_COUNT,//number of bits must change accordingly    
output reg set_freq = 0
);
reg [25:0] COUNT = 0;
always @( posedge CLOCK ) begin
COUNT = COUNT + 1;
set_freq <= ( COUNT == SET_COUNT )? ~set_freq: set_freq;
COUNT <= ( COUNT == SET_COUNT )? 0: COUNT;
end
endmodule

以上是我使用的代码和模块，任何帮助将不胜感激！！ 当我尝试将它运行到 basys 3 板时，我所有的 LED 都亮了，而我没有触摸任何按钮 我正在考虑使用修改后的去抖动单脉冲信号作为输入，这样做是为了消除按下按钮时产生的任何“噪音”。接下来使用分频器，我控制每个 LED 点亮所需的时间为 0.168 秒。所以我希望它会起作用，但它不会。
