The Importance of Model-Based Design in Embedded Systems
What is model-based design?
Model-based design helps integrate testing with design to identify and fix errors encountered during the process. As per current market expectations, the systems and devices are preferred to be customizable, compact, easily maintainable, and durable. To meet such market demands embedding complex microchips, microcontrollers and processors inside these systems is required. A model-based design approach is vital to verify and validate the working of the embedded systems as per the design and requirements.
In modern days it is difficult to find a smart device without the inclusion of an embedded computer system in it. Undoubtedly, embedded systems are necessary to differentiate products in terms of functionalities and features. An ideal embedded product goes through several processes such as integrating peripherals, processors, and software with functioning and testing compliance, developing the required platform with necessary programming tools, and languages designing the architecture. Model-based design is mostly used in industrial equipment, automotive, motion control, and aerospace applications.
Globally, there is a tremendous increase in the usage of compact devices and the sizes of microchips and processors keep shrinking, which requires the development of more sophisticated control systems. It is important to monitor application design processes and entire embedded control systems for the purpose of optimizing the overall system design. In this context, the model-based design approach is an efficient and effective means of understanding the parts of the products such as processors and commercial microcontrollers. Further, it helps to address complexities and difficulties that arise during the entire lifecycle of embedded application software through simulation of models and visual prototyping. MBD (Model-based design) covers optimization regarding cost, performance and functional behavior to deploy a product, from the concept of design to validation and testing.
Benefits of model-based design:
Model-based design helps in eliminating human errors and enables the reusability of the code. When opting model-based design gradually, enterprises have successfully achieved immediate results such as:
- Benefit 1: Faster time to demonstration and time to market with a quality product
- Benefit 2: Faster iteration without any need for major hardware changes
- Benefit 3: Handling sophisticated embedded systems with expanded capacity
- Benefit 4: Reusable models that can help in reducing development time and cost
- Benefit 5: Controlled design, analysis, and constant testing for improvement
- Benefit 6: Reduced number of prototypes, leading to higher ROI
By the use of MBD tools, engineers can
- Decrease development time
- Fast track product development
- By using fewer prototypes, resolve design problems if any
- Streamline workflows of testing and verification
