Motor vehicles drive the modern world, and have crucial roles in commerce, logistics, and recreation. With an estimated almost 1.5 billion cars on the planet1, and tens of millions of new vehicles being produced every year2, the importance of motor vehicles is only increasing with time.
Modern cars include many embedded systems to improve the safety and comfort of drivers and passengers by providing functions such as adaptive cruise control and tyre-pressure monitoring.
Many of the embedded systems used in modern cars are safety-critical. For these systems, it is essential that the software is checked to ensure that it functions correctly, as even slight faults could result in serious injury. The world over, automotive software is tested to the ISO 26262 standard to ensure functional safety.
Verification requirements for automotive software
Software verification is crucial to demonstrate that automotive software meets its functional and nonfunctional requirements. A range of activities support meeting verification requirements for automotive software, including the following.
Structural coverage analysis (code coverage analysis) for automotive software ensures that requirements-based testing has sufficiently tested the code structure. Structural coverage analysis is required to meet ISO 26262 requirements, and the required level of coverage depends on the criticality (ASIL) of the software being verified.
Multicore processing for real-time software makes systems less deterministic, as program behavior can be influenced by interference from software running on different processors. The use of multicore processing for automotive applications requires additional analysis and testing to demonstrate that software meets its timing deadlines in the context of multicore interference.
“We have been really impressed with Rapita throughout our relationship. RVS provides an extremely efficient and robust verification solution, and Rapita has worked together with us to support our preferred testing approach using test scripts. Based on the success we’ve had with RapiTest and RapiCover already, we’re looking forward to start using RapiTime to complete our rigorous testing for safety ”

Benefits of working with Rapita
Efficient testing & verification
Meeting project budgets is a top priority, which is why we focus heavily on making software testing and verification efficient.
We provide training and consultancy on making your testing and verification process more efficient, and our software includes key effort-saving features such as merging of results from different test runs and migration of coverage justifications.
At Rapita, we know that on-target testing is the gold standard, and our verification solutions are designed with this in mind.
With flexible integration strategies, RVS can integrate with almost any embedded target or simulator, regardless of available memory, bandwidth, or code size, and has been used for on-target verification of LEON and ARM processors.
RVS’s instrumentation is the lowest on the market, meaning fewer test runs are needed to collect results to verify your system.
Verification, your way
Every project and organization is different, and an efficient verification approach must align with your processes and development environment.
RVS integrates into your existing development environment, including build system, requirements management and application life cycle management tooling.
Using too many independent pieces of software slows projects down and causes a management headache.
Rapita and RVS provide solutions for all of the key verification activities you’ll need to perform that require dynamic analysis, meaning you can simplify both your verification strategy and your procurement.
A trusted partner
When you work with us, we do our best to support your needs, every time.
We regularly develop custom tools and solutions to meet specific verification needs.
Support is a cornerstone of our business, and our support team regularly exceeds our high service objectives. Check out some of our support testimonials to see we aren’t exaggerating.
