Modelling and Specification - A Deep Dive into Embedded System Abstraction
Modeling and specification are crucial phases in embedded system design, helping manage complexity and ensuring correctness. This chapter covers various levels and types of modeling, the use of UML diagrams, formal methods for verification, and techniques for specifying requirements. A systematic approach to these methodologies enhances communication, error detection, and overall product reliability in embedded systems.

What we have learnt
- Modeling is essential for managing complexity in embedded systems.
- There are different levels and types of system modeling including functional, architectural, and behavioral modeling.
- Formal methods provide rigorous, mathematical approaches for verifying system behavior.
Key Concepts
- -- Modeling
- An abstraction of a system that represents its properties and behaviors without building the actual system.
- -- UML (Unified Modeling Language)
- A standardized visual modeling language used to specify, visualize, construct, and document the artifacts of a software-intensive system.
- -- Formal Methods
- Mathematical techniques used for specifying, designing, and verifying software and hardware systems to ensure correctness and consistency.
- -- Functional Requirements
- Specifications that define what the system must do or the functions it must perform.
- -- NonFunctional Requirements
- Specifications that define how well the system performs its functions and the qualities it must possess.
- -- Data Flow Diagrams (DFDs)
- Graphical representations that illustrate how data flows through a system, showing processes and data stores.
