基于FPGA的按键消抖实验Verilog逻辑源码Quartus工程文件+文档说明，程序实现按键按下后数字加 1，并在数码管上显示出来，FPGA型号Cyclone4E系列中的EP4CE6F17C8，Quartus版本17.1。 module key_debounce( input clk, input rst_n, input key1, output [5:0] seg_sel, output [7:0] seg_data ); wire button_negedge; //Key falling edge ax_debounce ax_debounce_m0 ( .clk (clk), .rst (~rst_n), .button_in (key1), .button_posedge (), .button_negedge (button_negedge), .button_out () ); wire[3:0] count; wire t0; count_m10 count10_m0( .clk (clk), .rst_n (rst_n), .en (button_negedge), .clr (1'b0), .data (count), .t (t0) ); wire[3:0] count1; wire t1; count_m10 count10_m1( .clk (clk), .rst_n (rst_n), .en (t0), .clr (1'b0), .data (count1), .t (t1) ); //Count decoding wire[6:0] seg_data_0; seg_decoder seg_decoder_m0( .bin_data (count), .seg_data (seg_data_0) ); wire[6:0] seg_data_1; seg_decoder seg_decoder_m1( .bin_data (count1), .seg_data (seg_data_1) ); seg_scan seg_scan_m0( .clk (clk), .rst_n (rst_n), .seg_sel (seg_sel), .seg_data (seg_data), .seg_data_0 ({1'b1,7'b1111_111}), .seg_data_1 ({1'b1,7'b1111_111}), .seg_data_2 ({1'b1,7'b1111_111}), .seg_data_3 ({1'b1,7'b1111_111}), .seg_data_4 ({1'b1,seg_data_1}), .seg_data_5 ({1'b1,seg_data_0}) ); endmodule
