Circuit Design Education by Introducing Circuit Diagram‐Based CPU Design

Abstract

SUMMARYThere are many subjects that relate to electrical and electronics circuits. Practical education for those subjects usually introduce hardware description languages such as VHDL and Verilog HDL, but it is not easy to understand the relation to basic logic circuits drawn as circuit diagrams. In this paper, we introduce practical education in which basic digital circuits are drawn, simulated, and executed on an experiment board with a programmable logic device, and then newly designed 2‐bit CPUs which use those basic digital circuits are drawn, simulated, and executed on the experiment board. Students can learn basic digital circuits themselves, and their operations which relate to each other in the newly designed 2‐bit CPU. The effectiveness of the newly introduced practical education is confirmed by tests and a questionnaire survey.
