EDA課程設(shè)計拔河游戲機

實驗要求拔河游戲機（1）、設(shè)計要求設(shè)計一個能進行拔河游戲的電路。電路使用15個(或9個)發(fā)光二極管表示拔河的“電子繩”，開機后只有中間一個發(fā)亮，此即拔河的中心點。游戲雙方各持一個按鈕，迅速地、不斷地按動，產(chǎn)生脈沖，誰按得快，亮點就向誰的方向移動，每按一次，亮點移動一次。亮點移到任一方終端二極管時，這一方就獲勝，此時雙方按鈕均無作用，輸出保持，只有復(fù)位后才使亮點恢復(fù)到中心。由裁判下達比賽開始命令后，甲乙雙方才能輸入信號，否則，輸入信號無效。用數(shù)碼管顯示獲勝者的盤數(shù)，每次比賽結(jié)束自動給獲勝方加分。（2）、設(shè)計提示加/減計數(shù)器譯碼器得分計數(shù)顯示電路

2設(shè)計原理及總體框圖基本原理：由設(shè)計內(nèi)容可知，需要一個十進制的計數(shù)器，用于對雙方按鈕的次數(shù)計數(shù)。當led燈移動到一端時，那邊的選手得1分，通過比較模塊比較兩位選手的勝利的得分，并通過譯碼器顯示在數(shù)碼管上。設(shè)計要求用1MHz的頻率，而設(shè)計用到的是100Hz、5Hz和1Hz的頻率，所以要設(shè)計一個程序進行分頻。顯視控制部分設(shè)計要求在發(fā)光二極管上顯示游戲狀態(tài)，雙方每按十次，亮點向先按十次移動一次，對脈沖進行計數(shù)，每十次移一位。需接入一個清零端，用于復(fù)位。將以上程序組裝起來。當兩位選手其中一位選手先得到3分時，比賽結(jié)束，音樂響起，所以有一個音樂模塊。音樂music總體框圖：音樂music分頻器division防抖fangdou計數(shù)count比賽compete譯碼decodePlayer1Player2圖1總體框圖3程序設(shè)計總體設(shè)計電路圖2總體設(shè)計圖模塊設(shè)計和相應(yīng)模塊程序分頻器libraryIEEE;useIEEE.std_logic_1164.all;useIEEE.std_logic_unsigned.all;entitydivisionis port(clk:instd_logic; clk_100,clk_4,clk_1:outstd_logic);enddivision;architecturedivision_bodyofdivisionis signalcount1:integerrange0to4999; --signalcount1:integerrange0to1; signalcount2:integerrange0to124999; signalcount3:integerrange0to49; --signalcount3:integerrange0to1; signalclk1,clk2,clk3:std_logic; begin --得到100HZ的頻率 process(clk) begin if(clk'eventandclk='1')then if(count1=4999)then count1<=0; clk1<=notclk1; elsecount1<=count1+1; endif; endif; endprocess; --得到4HZ的頻率 process(clk) begin圖3分頻器 if(clk'eventandclk='1')then圖3分頻器 if(count2=124999)then count2<=0; clk2<=notclk2; elsecount2<=count2+1; endif; endif; endprocess; --得到1HZ的頻率 process(clk1) begin if(clk1'eventandclk1='1')then if(count3=49)then count3<=0; clk3<=notclk3; elsecount3<=count3+1; endif; endif; endprocess; clk_100<=clk1; clk_4<=clk2;clk_1<=clk3;enddivision_body;防抖模塊libraryIEEE;useIEEE.std_logic_1164.all;useIEEE.std_logic_unsigned.all;entityfangdou_player1is port(clk_100:instd_logic; player1_b:instd_logic; player1:outstd_logic圖4防抖1 );圖4防抖1endfangdou_player1;architecturefangdou_player1_bodyoffangdou_player1is signalmp1,mp2:std_logic; begin process(clk_100) begin if(clk_100='0')then mp2<=mp1; mp1<=player1_b; endif; endprocess;player1<=clk_100andmp1and(notmp2);endfangdou_player1_body;libraryIEEE;useIEEE.std_logic_1164.all;useIEEE.std_logic_unsigned.all;entityfangdou_player2is port(clk_100:instd_logic; player2_b:instd_logic; player2:outstd_logic );圖5防抖2endfangdou_player2;圖5防抖2architecturefangdou_player2_bodyoffangdou_player2is signalmp1,mp2:std_logic; begin process(clk_100) begin if(clk_100='0')then mp2<=mp1; mp1<=player2_b; endif; endprocess;player2<=clk_100andmp1and(notmp2);endfangdou_player2_body;計數(shù)器libraryIEEE;useIEEE.std_logic_1164.all;useIEEE.std_logic_unsigned.all;entitycountis port(clk_1:instd_logic; switch:instd_logic; player1,player2:instd_logic;圖6計數(shù)器 sum1,sum2:outintegerrange0to10圖6計數(shù)器 );endcount;architecturecount_bodyofcountis signalp1,p2:integerrange0to10; begin sum1<=p1; sum2<=p2; process(player1,player2,switch,clk_1) beginif(switch='1')thenif(clk_1='0')then--p1<=0;--p2<=0;if(player1='1')thenp1<=p1+1;endif;if(player2='1')thenp2<=p2+1;endif;elsep1<=0;p2<=0;endif;elsep1<=0;p2<=0;endif; endprocess;endcount_body;譯碼器libraryIEEE;useIEEE.std_logic_1164.all;圖7譯碼器useIEEE.std_logic_unsigned.all;圖7譯碼器entitydevodeis port(clk_1:instd_logic; clk:instd_logic; nixie_state1,nixie_state2:instd_logic_vector(1downto0); leds_state:instd_logic_vector(2downto0); nixie1:outstd_logic_vector(6downto0); nixie2:outstd_logic_vector(6downto0); leds:outstd_logic_vector(6downto0) );enddevode;architecturedevode_bodyofdevodeissignaltmp_leds:std_logic_vector(6downto0);signaltmp_nixie1:std_logic_vector(6downto0);signaltmp_nixie2:std_logic_vector(6downto0);signaltmp_nixiea:std_logic_vector(6downto0);signaltmp_nixieb:std_logic_vector(6downto0);beginleds<=tmp_leds;process(clk_1,leds_state,nixie_state1,nixie_state2)beginif(clk_1'eventandclk_1='0')thencaseleds_stateis when"100"=>tmp_leds<="0001000"; when"011"=>tmp_leds<="0010000"; when"010"=>tmp_leds<="0100000"; when"001"=>tmp_leds<="1000000"; when"101"=>tmp_leds<="0000100"; when"110"=>tmp_leds<="0000010"; when"111"=>tmp_leds<="0000001"; whenothers=>tmp_leds<="0001000"; endcase; endif; if(clk_1'eventandclk_1='0')then casenixie_state1is when"00"=>tmp_nixie1<="1111110"; when"01"=>tmp_nixie1<="0110000"; when"10"=>tmp_nixie1<="1101101"; when"11"=>tmp_nixie1<="1111001"; endcase; endif; if(clk_1'eventandclk_1='0')then casenixie_state2is when"00"=>tmp_nixie2<="1111110"; when"01"=>tmp_nixie2<="0110000"; when"10"=>tmp_nixie2<="1101101"; when"11"=>tmp_nixie2<="1111001"; endcase; endif; endprocess;nixie1<=tmp_nixiea;nixie2<=tmp_nixieb;process(clk_1,tmp_nixie1,tmp_nixie2,tmp_nixiea,tmp_nixieb)begin if(clk_1='1')then tmp_nixiea<=tmp_nixie1; else tmp_nixieb<=tmp_nixie2; endif;endprocess;enddevode_body;4引腳鎖定圖9引腳鎖定圖5硬件調(diào)試與結(jié)果分析編程下載及配置，選擇tool—programmer如下圖,重編譯，并進
