摘要
用硬件描述语言实现了一种新的用于EDA实验教学的电子密码锁设计。该设计能把串行的按键输入转换为逻辑矢量,当此矢量与预置的相等时锁便可以打开,不正确密码输入后的确认高电平将使设计发出警报;输入两组相同的8位数据和确认高电平就可以在锁被打开的状态下修改密码,而且整个设计的工作无需外部时钟。仿真结果和硬件验证表明该设计性能稳定可靠,具有较高的教学应用价值。
By using Hardware Description Language Achieved the new designed of Digital - Password - Lock that can applied in experimental Teaching of EDA. The design can convert serial key input into std_ logoe_ vector, the lock can be opened when the voctor is same to the preset, incorrect password input and high level of enter will make the sound of alarm. Two sets of the same data input and high level of enter will change the password, the design needn＇ t external clock. The timing simulation and hardware verification show that the performance of the Digital - Password - Lock is reliable and the design have high value of application in teaching.
