FPGAs for Learning Digital Electronics Concepts

Abstract

This article discusses the transformation of digital electronics education following the Covid-19 pandemic, highlighting the shift toward technology-based learning methods and active pedagogical approaches. As the pandemic has accelerated the adoption of online teaching systems, universities have invested in upgrading these systems to optimize resources. Digital electronics teaching has evolved to a more interactive and hands-on model, focused on collaborative and project-based learning, combined with simulators and digital design tools. It highlights the importance of preparing students for a technologically advanced working world, especially in the field of the Internet of Things, which has boosted the demand for skilled professionals in digital electronics. The article presents a detailed analysis of the methodology and results of teaching digital electronics in a subject taught in the third year of Industrial Electronics Engineering at the University of Almeria, incorporating sensors, actuators, and FPGA programming. Development projects are proposed using two platforms, one based on embedded systems with microprocessors like Arduino and the other on FPGA. Students select a platform and sensor to work with, allowing them to learn to program on platforms with substantial differences. According to statistics for the last six years, student performance improved with the transition from the traditional to the hybrid teaching mode, with a maximum success rate of 100% observed with the hybrid method in the 2022-23 academic year. The failure rate decreased, while absenteeism rates varied over the years. While there were initial challenges, including the timeconsuming nature of converting courses to online formats and the significant efforts instructors require to adapt to available tools, the trend favors distance education to ensure continuity in disaster situations. However, approaches that integrate hands-on learning are needed. Digital electronics students must acquire key skills to become successful engineers, and educators employ interactive methods to enhance their knowledge and future job competitiveness. Despite the challenge, students support systems that reflect real labor market conditions.
