In order to make electronic locks now more intelligent management, so that people more convenient to use, let it have a higher level of security and economy, the inadequacy of microcontroller based electronic locks for, we use EDA technology by QuartusⅡ work platform hardware description language design an electronic lock, and through an FPGA chip. Methods of VHDL using a top-down system are described and implemented in the FPGA chip CycloneⅡ. Designed to take full advantage of the resources of FPGA programmable features, high efficiency of the system can be upgraded and improved. Design can set any password lock, password lock than the average of four has higher safety and reliability, therefore, the use of FPGA development of digital systems, not only has high reliability, it is also extremely easy to upgrade and improvement, prospects are very good.
