The Need For Model-Based Design In Embedded Systems
It is difficult to imagine a world without technological enabled devices, and in recent times our dependency on these devices has increased multifold. We have integrated our devices in a way that most of our waking lives are spent using technology. Along with an increased demand for technology, the demand for systems that can be easily maintained, tailored for specific user needs, compact and durable models are also in high demand.
Embedded systems were traditionally designed to ensure a good processor system and a simplistic design that was dependable, met stringent cost needs and thermal performance requirements. This meant a wide use of multicore processors was not widespread yet. Modern-day market demands require that embedded products should be recyclable, durable, and highly customizable along with not following any traditional models of the design process.
To keep up with the growing demand for compact devices, the size of processors and microchips have been decreased. This has required the development of complex control systems. Embedded systems are the distinguishing factor between products in terms of features and capabilities. This advantage, however, comes at a cost. An embedded product goes through a number of processes, including designing its structure, constructing the product with programming languages and tools, peripherals, integrating processors, and software, and finally testing compliance and functionality.
To optimize the overall system design, the entire embedded control system and application design processes must be monitored.
In this case, the model-based device design approach would be an effective and efficient method of comprehending product components such as commercial microcontrollers and processors, as well as algorithms and code for the operation of both. Through visual prototyping and model simulation, model-based design in embedded systems assists in addressing various difficulties and complexities that arise during the lifecycle of embedded application software.
Traditional design processes typically transfer and handle design information in the form of text-based documents. These could be difficult to understand and open to interpretation prejudice. Engineers manually create embedded code and data from text-based documents, which is a time-consuming and error-prone process. There is also little control over whether changes will be implemented correctly.
Model-based design in embedded systems is a significant advancement in the development of embedded systems. When MBD in embedded systems is used effectively, it can provide a multipurpose design platform for optimizing the overall system design. It enables embedded software developers to distinguish between simulators and software development tools to create simulated models and test whether the algorithms work before writing any embedded code. System engineers can effortlessly note whether the entire system inclusive of all its components – mechanical, electrical, and embedded software will function as designed using virtual prototyping, even before the hardware is manufactured and ready for testing.
Model-based design in embedded systems is suggested to hardware design companies because of the following advantages:
- Teams are allowed to test the overall system design specification in a shared simulation environment.
- Controller design positioning on PLC hardware is made easier and manageable.
- Low-power controller products gain new engineering and manufacturing opportunities.
The size range of embedded systems is broad – From devices used in infrastructure to portable personal devices like smartwatches and music players, and even larger devices such as medical mapping systems. All of them require complex processors, microchips, and microcontrollers to be embedded in their systems. The model-based design system is imperative in the validation and verification of the seamless functioning of these embedded systems across various environments. Simulation can aid engineers in solving complex design problems through model-based design software in embedded systems during their product development projects.
