Embedded Software V&V
A3i Systems specializes in rigorous Software Verification and Validation (V&V), ensuring embedded systems meet the highest standards for safety, reliability, and compliance, particularly within the aerospace and automotive sectors. Our V&V process is meticulous, covering every aspect of the software lifecycle.
Core V&V Services and Compliance
We provide full-lifecycle V&V services for both software and hardware-related code
Aerospace V&V
Complete V&V development for embedded software under DO-178C and for FPGA/firmware under DO-254, covering all Design Assurance Levels (DAL A-C).
Automotive V&V
We conduct verification and validation services that comply with automotive functional safety standard ISO 26262 and cybersecurity standard ISO 21434.
Structural Coverage Analysis
A critical part of our process is demonstrating test coverage, including Statement, Decision, and Modified Condition/Decision Coverage (MCDC), as required for high DALs.
Analysis and Review
We perform Requirements, Design, and Code Reviews and conduct Worst-case Timing/Memory Analysis and Traceability Analysis to ensure every requirement is fully and correctly implemented.
Advanced Testing Methodologies
We utilize a comprehensive range of testing environments to catch defects at every stage of development
On-Target Testing
Hardware-Software Integration Test (HSIT)
We perform On-target Hardware-Software Integration Test and Software Unit Testing (On Target Unit Test) to verify the code's behavior on the actual target hardware.
Simulation and Emulation
Model-in-the-Loop (MIL)
Testing the software model in a simulated environment.
Software-in-the-Loop (SIL)
Testing the compiled code in a simulated environment on a host.
Processor-in-the-Loop (PIL)
Executing compiled code on a development board to mimic the target processor environment.
Hardware-in-the-Loop (HIL)
Final high-fidelity testing where the unit is connected to simulated sensors and actuators.
Certification Support & Tool Qualification
Our V&V capabilities directly support the certification process
Tool Qualification
We handle Tool Qualification activities as per DO-330 to ensure all development and verification tools used are reliable for safety-critical development.
Compiler Validation
We perform Compiler Validation as per CAST-12 to verify the object code is traceable to the source code and that the compiler behaves correctly on the target hardware.
Artifact Generation
We generate all necessary V&V artifacts required for the final Software Accomplishment Summary (SAS) package.
Tool Expertise
We are proficient with verification tools like LDRA and RTRT, as well as simulation tools like MATLAB Simulink, Model Sim, and LABVIEW.
