13 Comprehensive Chapters
Each chapter builds your software development process expertise systematically from foundations to advanced application.
Getting Started
Orient yourself within ISO 26262-6, understand the scope of software product development, and learn how Part 6 connects to Parts 3, 4, and 5 in the overall functional safety architecture.
V-Cycle Model
Understand the ISO 26262 software V-Cycle from requirements specification through unit design, implementation, and the corresponding test phases. Learn how each left-side activity generates verification criteria for the right side.
SW Safety Requirements
Transform technical safety requirements into software safety requirements. Master the derivation process, completeness criteria, ASIL attribution, and the essential properties of verifiable software requirements.
Architectural Design
Design the software architecture that satisfies safety requirements. Covers hierarchical decomposition, component interfaces, safety mechanisms at architecture level, and ASIL-appropriate design principles.
Unit Design & Implementation
Translate architectural components into detailed unit designs and source code. Learn design principles, defensive programming, modular design rules, and how coding guidelines integrate with the development process.
Integration Testing
Plan and execute software integration testing from module integration through software-hardware integration. Covers test strategies, interface testing, regression testing, and integration test coverage requirements.
Verification
Apply ISO 26262 verification methods including reviews, static analysis, dynamic testing, and formal methods. Understand ASIL-differentiated method applicability and independence requirements for verification activities.
Agile Integration
Integrate Agile development practices with ISO 26262 requirements. Learn sprint-level safety activities, definition of done for safety-relevant stories, risk-based planning, and how to maintain traceability in iterative development.
ASPICE Framework
Align ISO 26262 software development with ASPICE (Automotive SPICE) process capability assessment. Understand the synergies, overlaps, and complementary requirements between the two frameworks.
Bidirectional Traceability
Establish and maintain bidirectional traceability from safety goals through requirements, architecture, implementation, and test cases. Learn traceability tools, matrix structures, and automated traceability techniques.
Toolchain Qualification
Qualify development tools including compilers, static analyzers, code generators, and test frameworks per ISO 26262-8 Clause 11. Understand tool confidence levels and qualification methods.
CI/CD Practices
Implement continuous integration and continuous delivery pipelines that maintain ISO 26262 compliance. Covers automated safety checks, regression gates, change impact analysis, and release management.
Case Studies
Apply the complete ISO 26262-6 software development process to real automotive systems including EPS software, brake control firmware, and an ADAS perception pipeline with ASIL decomposition.
