In a recent paper by Ajao et al, adopted bottom-up techniques of learning embedded system and microcontroller-based related courses were achieved by making apparent practicality and exhibiting the teaching approach “learn-while doing” on the embedded system projects, which helps student connect their theoretical and practical knowledge, reasoning with embedded system design and other related lessons. Such increases designed efficiency, understanding and clearly highlights the potential for rapid system development from simple to high complex intensive circuit design using computer aided design or engineering simulation tools for the logic circuit, electronics circuit or others system of microcontroller-based developments.
“Bottom-up techniques and hands-on laboratory of such model can greatly facilitate the skills of researchers, engineers, technologist, technician and students by performing efficient and time-saving in design experiments that have the potential to handle any project without the need for the use of costly resources associated with pre-engineer designed presented in the paper ajao et al”.
Ajao et al shows how embedded system can be learned practically, understand and developed from the simple circuit designed and simulation stages, breadboarding, and soldering before ever embarking on the final packaging by frequent hands-on laboratory using bottom-up design techniques. In virtual circuit design and simulation, all the electronics components entail in the design were assembled into the schematic editing window of PVSM with the aid of virtual electrical path way, and loaded the .hex file to the microcontroller chip for the simulation. In this way, explicit modular programming can be thought of in terms of being logically execution for such design and simulation techniques.
The author, suggested that “Advancement in embedded system design and microcontroller-based circuit simulation and development can be motivate by the researcher in the academic and industry to fully engaged and concentrate in hands-on laboratory practiced. Since it is multi-disciplinary field in engineering, and is finding as most difficult course to the learners and the developers. Also, it will enhance learner skills and the technological approaches in embedded system designed and development.
The design, programming and simulation is often seen as a first steps towards the development of more complex models of later stage embedded system improvement like mobile phone, robotic system, automation teller machines (ATMs), global positioning system (GPS), digital video cameras and aerospace systems. Mathematical, programming and computational modeling is playing an increasingly important role in helping engineers, and researcher in understanding the different aspects of microcontroller-based system lively. Microcontroller-based experiments and simulations, such as those performed in the paper of ajao et al, gives researchers, engineers, and learners the tools and opportunity to observe different effects of embedded system design in both virtual and realistic life scenario. This will inevitably lead to more rapid improvements in effectual engineering design strategies as well as aiding in the discovery of new forms of high-tech embedded system development.
Established equipped and standard embedded system laboratories within the tertiary institution and industries could be used greatly in various kinds of system planning and design, which personalized to improve dynamics or optimal on the complex design of embedded system through practiced of advanced computer simulation. The ability to use advanced computational and designed methods to simulate the virtual stage of pre-engineering design greatly reduces time to market and use of moderate laboratory resources, as well as diminish financial costs involved.
