As a electronics product, digital encrypted lock has more advantages over traditional lock in our daily use. Meanwhile, the development of EDA technology takes a breakthrough to the performance of electronicsproducts, which saves the resources and enhances the reliability. In this paper, through analysis of the digital encrypted lock’s function, we divided the whole system into several modules. Then, we described each module by VHDL (Very High-Speed Integrated Circuit Hardware Description Language) and drew the graphic files. We simulated the files and finally got the results. When you input correctcodes, the door opens and the light is green. When ...
