軟件：Quartus

語(yǔ)言：VHDL

代碼功能：

數(shù)字顯示自動(dòng)記分器

1.設(shè)計(jì)一個(gè)射擊用的數(shù)字顯示自動(dòng)計(jì)分器,電路共設(shè)18個(gè)模擬開關(guān),K1~K18,分別代表射擊者射中的目標(biāo),射中K1~K9分別得1~9分,射中K10~K18分別得10~90分;

2.要求每射中一次(K1~K18開關(guān)拔動(dòng)一次)單發(fā)計(jì)數(shù)顯示器能自動(dòng)顯示得分?jǐn)?shù),顯示2秒后自動(dòng)消失；

3.每射中一次均應(yīng)將射擊的得分?jǐn)?shù)累計(jì)并顯示;

4.電路應(yīng)具有復(fù)位功能,即每局結(jié)束后,應(yīng)將各計(jì)數(shù)器自動(dòng)清0,為下一次記分作好準(zhǔn)備(手動(dòng)復(fù)位)；

5.單發(fā)計(jì)數(shù)顯示和累加計(jì)數(shù)顯示應(yīng)分開;

6.脈神信號(hào)源(自行設(shè)計(jì))為1KHz頻率。
