為了實現(xiàn)以上四點設計要求，把總方案分成頂層（top）模塊、液晶顯示（lcd）模塊、液晶控制（lcdcontroller）模塊、倒計時（discount）模塊、計分（jifen）模塊共五個模塊。其中倒計時模塊和計分模塊融合在頂層模塊里。

頂層（Top）模塊用于對整個電路的邏輯設計和各個狀態(tài)的轉換以及對子模塊的調用。

液晶顯示（Lcd）模塊則用于顯示相關字符。需要先把要顯示的字符寫在程序中備用，并編碼。采用譯碼器的方式調用某串字符。故該模塊的輸入為需要調用的字符的編碼、競賽進行到第幾個問題（共五個）的編碼以及時鐘等。

倒計時（discount）模塊用于比賽中的計時。先把50M的頻率分成1HZ的頻率進行記秒。采用譯碼器的原理把倒計時顯示在對應的數(shù)碼管上。

計分模塊用于實時顯示選手的得分。同樣采用譯碼器原理進行數(shù)碼管的顯示。輸入為選手的得分。

復制代碼

結論以及結果說明
系統(tǒng)運行在Cyclone II開發(fā)板上，程序代碼運行在Quartus II6.0上。該設計中搶答時間和回答時間可以根據(jù)具體情況進行調整。在計時分頻環(huán)節(jié)把50M的頻率分成1HZ的頻率時通對需要計數(shù)的值進行判定。同樣的在LCD顯示模塊里為了讓模塊可以正常工作，并且簡化顯示流程，對比LCD1602的參考手冊采用把時鐘分成約100HZ 讓LCD只需不斷地寫入指令或數(shù)據(jù)即可。運行結果可以達到設計效果。
