数字密码锁的设计与实现



一．实验目的

1. 学习VHDL的综合设计应用

2. 学习数字密码锁的设计



二．实验内容

　　设计一个数字密码锁，对其编译，仿真，下载。

数字密码锁具体要求如下：　　

1.系统具有预置的初始密码“00000001”。

2.输入密码与预存密码相同时，开锁成功，显示绿灯，否则开锁失败，显示红灯。

3.具有修改密码功能。修改密码时，先开锁，开锁成功才可以修改。

4.系统同时具有关锁功能。关锁后，显示红灯。

5.密码由拔码开关表示，开锁由按键表示。

6具有一个复位按键。按键后，回到初始状态。

-VHDL Digital Design and Implementation of lock

1. Purpose of the experiment

1. VHDL Integrated Design and Application of Learning

2. Learning digital code lock design



2. Experimental content

Design a digital lock on their compilation, simulation, download.

Digital code lock specific requirements are as follows:

1. System has preset the initial password "00000001."

2. Enter the same password with the stored password, unlock successful, a green light, or unlock failed to show a red light.

3. With the change password function. Modify password, the first lock, unlock success can modify.

4. The system also has off lock. Shut up after the red light.

5. The password code from the pull switch that unlock the keys, said.

6 has a reset button. Button, the return to initial state.
