我是穆罕默德，我正在尝试编写一个带有异步复位的BCD计数器，该计数器连接到一个按钮。它也可以获得8位输入。 我的所有代码和模块都工作正常，除了Debouncer，我用它来去除按钮。模块本身工作正常，但当我实例化它时 ＆＃34;分块块在块中未连接。 它将从设计中删除。＆＃34; 出现！ 这是我的主要代码：
module BCD_main(
input clk,
input reset,
input [7:0] inp,
output wire [6:0] main_out0,
output wire [6:0] main_out1
);
reg [7:0] in ;
reg [7:0] count ;
reg [3:0] out0 ;
reg [3:0] out1 ;
wire clk_main ;
wire reset_in ;
assign reset_in = reset ;
wire reset_out ;
wire clk_en ;
assign clk_main = clk ;
initial begin
out0 <= 0 ;
in <= 0 ;
count <= 0 ;
out1 <= 0 ;
end
Enable count_enable (
.En_clk(clk_main),
.CE(clk_en)
);
Debouncer debounce (
.clk(clk),
.pb_in(reset_in),
.pb_out(reset_out)
);
always @(inp) count <= 0 ;
always @(posedge clk or negedge reset_out)
begin
if (~reset_out) begin
out1 <= 0 ;
out0 <= 0 ;
in <= 0 ;
end
else if (clk_en) begin
count <= count + 1 ;
in <= inp + count ;
if ( in <= 9) begin
out1 <= 0 ;
out0 <= in ;
end
else if(in > 9 && in <= 19) begin
out1 <= 1 ;
out0 <= in - 10 ;
end
else if( in > 19 && in <= 29) begin
out1 <= 2 ;
out0 <= in - 20 ;
end
else if( in > 29 && in <= 39) begin
out1 <= 3 ;
out0 <= in - 30 ;
end
else if( in > 39 && in <= 49) begin
out1 <= 4 ;
out0 <= in - 40 ;
end
else if( in > 49 && in <= 59) begin
out1 <= 5 ;
out0 <= in - 50 ;
end
else if( in > 59 && in <= 69) begin
out1 <= 6 ;
out0 <= in - 60 ;
end
else if( in > 69 && in <= 79) begin
out1 <= 7 ;
out0 <= in - 70 ;
end
else if( in > 79 && in <= 89) begin
out1 <= 8 ;
out0 <= in - 80 ;
end
else if( in > 89 && in <= 99) begin
out1 <= 9 ;
out0 <= in - 90 ;
end
else if ( in > 99) begin
out1 <= 0 ;
out0 <= 0 ;
end
end
end
DipSWtoSS SevSegDec(
.DpSw_1(out0),
.DpSw_2(out1),
.SevSeg_1(main_out0),
.SevSeg_2(main_out1)
);
endmodule
这是debouncer模块：
module Debouncer(
input clk ,
input pb_in,
output reg pb_out
);
reg [12:0] count13 ;
initial begin
pb_out <= 1 ;
count13 <= 0 ;
end
always @(pb_in) count13 <= 0 ;
always @(posedge clk) begin
count13 <= count13 + 1 ;
if (count13 == 13'd8000)
pb_out <= pb_in ;
else
pb_out <= 1 ;
end
endmodule
