基于FPGA的电子密码锁设计

湖南人文科技学院本科生毕业设计说明书The FPGA-Based Design of Electronic Combination LocksAbstract:For FPGA-based cipher locks,EDA technology should be used in turn,with a series ofchanges,unlocking and display in VHDL language.In fact,VHDL can be put into use as aprogramming logic device,which mainly includes large-capacity CPLD and FPGA practicalapplications.If you use the previous Boolean equations or port-level description techniques,itis difficult to implement them quickly and efficiently.VHDL is easy to design for largecircuits,and very quickly,it is a scale language whose design description can be supported byvarious tools and can be implemented in different configurations.In this paper,the design ofthe password lock is the same,through the use of VHDL from the top down,the detaileddesign.The password lock thus designed is usually small in size and high in energy efficiency,and can effectively reduce the actual power loss and the maintenance is relatively simplewithout requiring relatively high production cost.Key Words:Password lock;FPGA;VHDL;EDA technology.第2页共13可
