資源簡(jiǎn)介
1.在圖形編輯器中設(shè)計(jì)一個(gè)3位的十進(jìn)制加法計(jì)數(shù)器，以xxxcnt3.gdf命名保存(‘xxx’為您的姓名拼音首字母)。器件設(shè)定為EPM7128LC84-6。要求能夠從0計(jì)數(shù)到999。從999歸零時(shí)產(chǎn)生一個(gè)高電平的報(bào)警信號(hào)。進(jìn)行波形仿真，驗(yàn)證功能正確。分析此電路的最高計(jì)數(shù)頻率。
2.修改這個(gè)計(jì)數(shù)器的歸零值，使其計(jì)數(shù)到119就歸零，增加異步清零功能，加法計(jì)數(shù)/減法計(jì)數(shù)控制功能。
3.在文本編輯器中使用VHDL語言設(shè)計(jì)一個(gè)D觸發(fā)器,具有反向輸出端。命名為xxxdff.vhd，仿真驗(yàn)證。
