vivado交通燈設(shè)計(jì)verilog代碼ego1板紅綠燈時(shí)間可修改

名稱：vivado交通燈設(shè)計(jì)verilog代碼ego1板紅綠燈時(shí)間可修改（代碼在文末下載）

軟件：VIVADO

語言：Verilog

代碼功能：

十字路口紅綠燈設(shè)計(jì)；

1、每次通行時(shí)間可在0-99秒內(nèi)設(shè)定，可以通過按鍵修改通行時(shí)間。

2、路口四邊均設(shè)紅黃綠三色信號(hào)燈和用于計(jì)時(shí)的兩位數(shù)碼管顯示時(shí)間(十進(jìn)制數(shù))。

3、黃燈亮?xí)r，要求每秒閃亮一次。
