基于FPGA的电子密码锁设计

The FPGA-Based Design of Electronic Combination Locks

基于FPGA设计的电子密码锁,运用EDA技术自顶向下的方法,采用硬件描述语言VHDL实现了密码锁的解锁、密码修改、报警提示及液晶显示功能。硬件测试结果表明,密码锁功能丰富、操作简单、安全性高、易于维护和升级。

Based on FPGA,the author of this paper has designed a kind of digital combination lock with the top-down design EDA method and VHDL to unlock the combination lock,sett the password,warn failures and display with LCD.The results show that the combination lock has the advantages of rich functions,easy operation,high security,great reliability,and effortless maintenance and upgrade.
