Digital and analysis of alarm clock design based on Multisim

With the development of technology and the times, virtual simulation technology represented by Multisim has been widely used, and simulation technology is also an indispensable part of industrial design. This article uses Multisim simulation technology to design and complete a digital electronic clock based on a 74ls160 counter, composed of a decoder, a display, a numerical comparator, and an alarm clock. In this design, digital circuits are used to display and adjust "time", "minute", and "second". By using various integrated digital chips to build circuits to achieve corresponding functions. It successfully realizes the functions of calibrating the time, reporting the time on the hour, and alarming the clock. Compared with traditional electronic clocks, it has the characteristics of accurate travel, intuitive display, and no mechanical transmission, The research in this paper will contribute to the further application of virtual simulation software in the design of small devices, and will not lay a foundation for the future industrial design process.
