Concept Definition

In this section a concept for the implementation will be discussed. Inputs for this concepts are both the requirements of ISO26262 Part-6 Chapter 8+9 and ASPICE SWE 3+4.

Detailed Design#

In this step, the components are broken down into smaller, independent units that can be tested separately during the unit testing phase. The basis for this decomposition are the Component Requirements and the Component Architecture. The decomposition shall support the implementation and testing of the component’s requirements while adhering to the design principles and patterns established in the architecture.

Following the Detailed Design Template Detailed Design Templates, we must document the design decisions and constraints that guide the decomposition of the component into multiple units. These decisions should be made based on the following ideas:

  • Design principles

  • Design patterns

  • Testability strategies

The goal is to ensure that the decomposition supports reusability, maintainability, scalability, extensibility and ease of testing.

The detailed design and implementation should follow an iterative approach, allowing for continuous improvements in quality through multiple cycles of refinement.

The implementation concept intentionally stays at a high level. Practical guidance for unit decomposition, source-code documentation, optional diagrams and naming consistency for traceability is defined in Implementation Guideline.
