14 Comprehensive Chapters
Each chapter builds your verification & validation expertise systematically from foundations to advanced application.
V&V Fundamentals
Establish the distinction between verification and validation in ISO 26262 context. Understand verification aims, confirmation measures, and how V&V activities are distributed across Parts 4, 5, 6, and 8.
V-Model Overview
Navigate the ISO 26262 V-Model from concept through system integration, understanding how each right-side verification activity corresponds to a left-side development activity and what verification criteria are required at each level.
Unit Testing
Design and execute unit tests per ISO 26262-6 requirements. Covers test case derivation methods, boundary value analysis, equivalence class partitioning, and structural coverage requirements per ASIL level.
Integration Testing
Plan and execute software and hardware-software integration testing. Learn integration test strategies, interface testing, stub and driver design, and coverage requirements for integration test levels.
System Testing
Validate the complete item against system-level requirements. Covers functional testing, safety mechanism activation testing, boundary testing at system level, and regression testing strategies for system integration.
Vehicle Testing
Conduct vehicle-level validation including driving tests, fault injection scenarios, boundary condition evaluation, and safety goal verification on real vehicles or proving grounds.
Coverage Requirements (MC/DC)
Master structural coverage criteria from statement coverage through MC/DC (Modified Condition/Decision Coverage). Understand ASIL-specific requirements, how to achieve MC/DC, and tool support for coverage measurement.
Independence Requirements
Understand and implement independence requirements for verification activities per ISO 26262. Learn the difference between I1, I2, and I3 independence levels and how to demonstrate independence in project organization.
Test Case Derivation
Derive test cases from multiple sources including requirements, risk analysis, design, and fault models. Learn systematic derivation methods for both black-box and white-box testing with traceability to test coverage goals.
Back-to-Back Testing
Apply back-to-back testing for model-based development and for comparing production code against reference implementations. Understand when back-to-back testing is required, how to set it up, and what coverage it provides.
HIL/SIL/MIL
Design and execute Model-in-the-Loop, Software-in-the-Loop, and Hardware-in-the-Loop test environments for automotive functional safety verification. Covers environment modeling, fault injection capability, and equivalence arguments.
Fault Injection
Apply fault injection testing to verify safety mechanism effectiveness. Covers software fault injection, hardware fault injection via HIL, and fault injection methodology for achieving diagnostic coverage demonstration.
Review & Inspection
Apply formal review and inspection methods including walk-throughs, technical reviews, and inspections per ISO 26262. Learn checklist design, review records, and how to demonstrate review independence for ASIL-C and D.
Evidence Capture
Systematically capture and organize V&V evidence for the safety case. Learn test report requirements, coverage evidence formats, review records, and how to assemble assessment-ready V&V documentation packages.
