Abstract

To improve the teaching quality of sequential logic circuits in the Digital Electronic Technology course and meet the requirements for cultivating college students' innovation ability under the background of New Engineering, this paper takes the design and simulation of an N-base counter as a teaching case and explores a teaching mode that combines theoretical teaching with simulation practice. In view of the shortcomings in current experimental teaching, the paper proposes a systematic teaching method of analysis first and simulation verification afterward. First, theoretical analysis is carried out for the three core functional modules of counting, decoding, and display. Second, Multisim software is used to conduct simulation verification of typical counters such as septenary, sexagesimal, and twenty-four-base counters. Different-base counters are formed by changing the connections between chips and peripheral circuits, so that the simulation results are consistent with the theoretical analysis. This teaching method can effectively stimulate students' learning interest and deepen their understanding and mastery of the analysis and design of arbitrary-base counters. By transforming abstract theoretical knowledge into intuitive simulation results, the teaching effect and quality are significantly improved.
