名稱(chēng)：十字路口交通燈控制器VHDL代碼Quartus仿真

軟件：Quartus

語(yǔ)言：VHDL

代碼功能：

十字路口交通燈控制器的VHDL設(shè)計(jì)(每班21號(hào)以后的單號(hào))

設(shè)計(jì)要求:利用硬件描述語(yǔ)言和FPGA器件,設(shè)計(jì)實(shí)現(xiàn)一個(gè)由一條主干道和一條支干道的匯合點(diǎn)形成的十字交叉路口的交通燈控制器,具體要求如下：

(1)主、支干道各設(shè)有一個(gè)綠、黃、紅指示燈,兩個(gè)顯示數(shù)碼管。

(2)在主干道和支干道的兩個(gè)方向上各設(shè)有一組綠、黃、紅交通燈,其中一個(gè)方向是綠燈、黃燈、紅燈,另一個(gè)方向是紅燈、綠燈、黃燈。

(3)數(shù)碼管以倒計(jì)時(shí)的方式顯示允許通行或禁止通行的時(shí)間,主干道每次放行40s60s70s,支干道每次放行20s30s40s50s,在每次由亮綠燈變成亮紅燈的轉(zhuǎn)換過(guò)程中要亮5s的黃燈作為過(guò)渡,并進(jìn)行減計(jì)時(shí)顯示,時(shí)鐘信號(hào)由實(shí)驗(yàn)箱上50MHz分頻得到1H。

(4)設(shè)置交主干道優(yōu)先通行電路(選做

各放行定時(shí)器的實(shí)體名為:XXX放行時(shí)間,XXX為自己姓名的首字母。

任務(wù)學(xué)號(hào)對(duì)應(yīng):21、23、25號(hào)選(70150);27、29、31選(60140)33、35、37-選(5030);39、41、43選(40120)。
