Rapita Verification Suite: On-target software verification for critical embedded systems
Why choose Rapita Verification Suite?
Run requirements-based tests on your code
RVS’s unit, integration and system testing solution, RapiTest, helps you write and run requirements-based tests easily on host or target.
With easy-to-write and easy-to-review yet feature-rich test formats and the ability to create multithreaded tests and test code elements such as generics and private types (without having to write source code), RapiTest cuts the cost of requirements-based testing.
Produce coverage evidence including MC/DC from tests
RVS’s structural coverage analysis solution, RapiCover, automatically instruments your code for structural coverage analysis (up to MC/DC) and collects results while it runs on host or on target.
With an efficient verification workflow, flexible integration strategies and extremely low target overheads, RapiCover has helped customers like Collins Aerospace and OHB Sweden cut their testing effort by up to 40%.
Analyze execution time including worst-case timing on-target
RVS’s execution time analysis solution, RapiTime, automatically instruments your code to measure timing behavior and collects timing results while your application runs on your target hardware.
RapiTime’s hybrid worst-case execution time (WCET) calculation leverages the benefits of static analysis and measurement-based approaches to produce WCET results that represent behavior on the real system and provide a safe upper bound on WCET while minimizing pessimism.
Understand program scheduling behavior
RVS’s scheduling visualization solution, RapiTask, collects task-level timing results during program execution and lets you view these graphically so you can understand your system’s scheduling behavior.
Using RapiTask, it’s easy to locate rare timing events in your system and identify system bottlenecks, and as RapiTask is platform-agnostic, you’ll only have one tool to learn no matter which RTOS you’re working on.
Produce evidence for DO-178 and ISO 26262 certification
Get ready for DO-178C and ISO 26262 certification with our qualification kits. Our off-the-shelf qualification kits and qualified target integration service helps you on the road to qualifying your use of RVS.
Many features of RVS are qualified, including our instrumentation and coverage merging, which has saved customers like Collins Aerospace a huge amount of manual effort.
The Rapita Verification Suite (RVS) has been used in the critical embedded industry for over 15 years and supported a number of avionics projects globally. Qualification kits for qualified RVS products have supported more than 20 DO-178B and C certification projects up to and including DAL A.

Zero-footprint tools compatibility
To support zero-footprint analysis, a platform must have certain properties, and a Platform Support Package must be available for the platform.
The required properties for zero-footprint analysis include the compiler, instruction set, and real-time operating system. The platform must also be capable of generating branch traces from which program execution behavior can be understood.
Zero-footprint RVS tools support the analysis of code written in any language that targets machine code.
For more information on the compatibility requirements of a specific zero-footprint RVS tool, select it from the Solutions menu and navigate to the Compatibility tab.
Requirements
Software analysis by zero-footprint RVS tools has the following requirements:
- The platform (target and any external devices e.g. debuggers) must be capable of producing a branch trace without gaps to ensure that the full program trace can be reconstructed.
- The OS needs to make context switches observable. For some systems, supporting this may require modifications to be made to the OS.
- A Platform Support Package (PSP) is needed for RVS to interface with the development environment, including the target hardware and trace capture mechanisms, in order to convert the branch trace into a format that the RVS tool understands and disassemble the executable and parse the resulting object code.
PSPs are developed to be compatible with the following:
For a list of components that are already supported, see below. Note that we can add support for some components not listed below.
For detailed information on the requirements for zero-footprint tracing, see our Technical note.
For more information, contact info@rapitasystems.com.
Compilers
Platform Support Packages (PSPs) must be able to disassemble executables for further analysis. Typically, tools required for this are supplied as part of a toolchain unique to each compiler. The compilers PSPs already support are listed below:
- Arm Compiler
- CC-RH850
- Clang
- GCC
We can develop support for other compilers. For more information, contact us at info@rapitasystems.com.
Instruction sets
When code has been disassembled, Platform Support Packages (PSPs) must be able to understand the instruction set of the object code so they can parse it before it is used for subsequent analysis by zero-footprint RVS tools. The instruction sets PSPs already support are listed below:
- 68k
- AArch64
- ARM
- PowerPC
- RH850
- VISIUM
- x86
We can develop support for other instruction sets. For more information, contact us at info@rapitasystems.com.
Branch traces
For it to be possible to analyze executables generated by a platform by zero-footprint RVS tools, it must be possible to collect a branch trace from the platform*. Some targets generate branch traces by default, for example:
- Boards that have been developed to meet at least Class 2 of the Nexus message-based trace protocol
- ARM boards including an ARM ETM component
- Custom boards developed to produce branch traces
A debugger may be used to collect these branch traces from the target. Simulators may generate branch traces, or it may be possible to modify them to do so. Each Platform Support Package (PSP) is designed to support branch traces collected by a specific debugger or from a specific simulator. The debuggers and simulators PSPs already support are listed below:
|
Debuggers |
Simulators |
|---|---|
|
Lauterbach TRACE32 |
QEMU † |
|
PARTNER-Jet2 |
We can develop support for other debuggers and simulators. For more information, contact us at info@rapitasystems.com.
*In some cases, other approaches may be possible, such as using a branch map.
Real-time operating systems
For it to be possible to analyze executables generated by a platform by zero-footprint RVS tools, it must be possible to collect information on context switches made during software execution. Whether this is possible or not depends on the real-time operating system (RTOS) used and its configuration. Platform Support Packages must be able to understand context switch information to support further analysis of an executable by zero-footprint RVS tools. The RTOSs PSPs already support are listed below:
- eMCOS for AUTOSAR Adaptive Platform
- eMCOS for AUTOSAR Classic Platform (RV850)
- FreeRTOS
- SafeRTOS
- SYSGO PikeOS®
- Bare Metal (no OS)
We can develop support for other real-time operating systems. For more information, contact us at info@rapitasystems.com.

Zero-footprint RVS tools can be used to analyze software from multicore systems.
Suitable branch trace(s) can be collected in one of two ways:
- Collecting a separate branch trace from each core
- Collecting a branch trace that includes results from all cores, where it’s possible to derive the core from which each branch was taken
Frequently asked questions
-
What is RVS?
RVS is the leading toolsuite for the verification of critical software.
Used globally in the aerospace and automotive industries, it includes tools for functional and requirements-based testing, timing analysis including worst-case execution time analysis, and structural code coverage analysis.
-
How does RVS work?
RVS works by combining static and dynamic analyses of software execution to gain an understanding of the software architecture. Using this understanding, RVS injects and/or instruments code to perform a variety of functions including generating and running functional test harnesses, analyzing the structural coverage achieved during functional testing, and analyzing the timing behavior of code being executed.
By integrating into the existing development environment and continuous build servers, RVS reduces the cost of software verification. The flexible nature of RVS integrations and its extremely low instrumentation overheads support its use on even the most complex systems, including multicore systems.
-
Which industries use RVS?
We have been providing state-of-the-art verification solutions to companies in the aerospace, automotive, and space software industries since 2004, as demonstrated by our case studies.

-
Can I use RVS on my target, which has limited RAM and/or ROM?
The instrumentation overheads for RVS tools are the lowest in the market, and the tools can support zero-instrumentation overhead in some cases. Because of this, RVS can generate verification data from your source code in fewer builds than possible using other tools. For example, in a recent customer evaluation, RapiCover instrumentation overhead was 4 to 5 times lower than competitor tools, leading to a 92% reduction in the number of builds necessary to test the code base. If necessary, you can configure RVS tools to instrument your code in multiple builds and compile collected data into a single report.
-
Which host operating systems can RVS be used on?
RVS tools can be run on the following x86-64 operating systems:
- Windows 10 and 11
- Windows Server 2019+

RapiTest, RapiCover and RapiTime (including zero-footprint versions) include custom plugins to integrate with Jenkins and Bamboo. RapiTest and RapiCover results can also be displayed in a range of other continuous integration tools through the JUnit and Cobertura plugins, which are compatible with most continuous integration software.
-
How does RVS support multicore timing analysis?
RVS, Rapita's verification toolsuite, supports multicore timing analysis by letting you create and run multicore timing tests, automatically capture verification results as these tests run on your multicore platform, efficiently analyze collected results, and generate compliance evidence when your analysis is complete.
RVS includes a range of features that support multicore timing analysis, including:
- RVS supports the collection of a range of metrics during testing, including execution time results and values from hardware event monitors on your platform, such as the number of cache hits and cache misses.
- RVS makes it easy to view and analyze multicore timing results by letting you filter your results on the performance metrics and tests you want to see and letting you select a baseline against which to compare your results.
- RVS lets you generate custom exports to provide compliance evidence. Custom exports reduce your documentation effort by automatically pulling in results from your reports and automatically reporting pass/fail status based on your success criteria.
- RapiTime lets you automatically merge timing results collected during multicore timing analysis into a single report. This lets you collect and analyze results from multiple test runs, multiple builds and multiple time points, and supports running results on multiple test rigs.
-
How long has RVS been used for software verification?
The Rapita Verification Suite (RVS) has been used in the critical embedded industry for over 15 years and supported a number of avionics projects globally. Qualification kits for qualified RVS products have supported more than 20 DO-178B and C certification projects up to and including DAL A.
-
My project includes subcontracting organization(s) and I have confidentiality concerns. Can RVS help me?
To support verification, RVS stores a copy of your source code in your verification results. RVS lets you remove this copy of your source code from your RVS project, so any subcontracting organizations you’re working with can’t see your proprietary information. A subcontracting organization can then verify aspects of your software using the redacted results, and you can later restore the copy of your source code for your internal use by merging your results.
Note that, as running functional tests requires access to the source code under test, this feature is not available for RapiTest.
-
How does RVS support Enterprise licensing?
Floating RVS licenses follow an “Enterprise” model. You can use them across geographical boundaries*, in different projects, with different users, and share them with suppliers working on the same project.
*Some floating licenses may be restricted to use within a specific geographical region. Where this is the case, this is agreed before licenses are issued.
-
Can I create and manage groups for my floating RVS licenses?
Yes, you can create and manage groups of users for your floating RVS licenses. You can restrict each group to only serve licenses to specific hostnames or IP addresses. This allows you to reserve licenses for specific groups or specific purposes such as supporting the use of RVS on a continuous integration server.
Any licenses that you don’t reserve will remain available as floating licenses that can be shared among different users and geographic locations.
-
Can I use RVS to test my SCADE model code on target?
Yes. RapiTest lets you automatically convert your existing SCADE Test tests into RapiTest tests so you can test your code on target.
You can also use RapiTime to support on target worst-case execution time analysis of your model code and any handwritten code you use in your project.
-
Can I use RVS to verify my code that runs on Deos?
Yes. RVS has an out-of-the-box integration with Deos, which makes it possible to generate an RVS project and integration in just 3 clicks from an existing OpenArbor project.
This benefits from the debug capabilities offered by Deos to automatically apply configuration settings needed for your RVS project.
The generated project and integration lets you use RapiCover for on-target structural coverage analysis, RapiTime for on-target worst-case execution time analysis, and RapiTask to let you visualize the scheduling behavior of your code.
-
How does RVS support the analysis of shared code compiled by build systems with multiple executables?
RVS supports the analysis of shared code compiled by build systems with multiple executables by letting you specify the source files that will be compiled in each executable.
If you have functions that are declared in multiple components with the same name but have different definitions, RVS can treat each such function uniquely, for example to provide separate coverage in RapiCover and separate execution time results in RapiTime.

How can RVS help me understand my code base?
RVS analyzes the structure of your code and presents information on your code’s structure, helping you understand your code and its dependencies in a variety of forms such as the following:
- RVS analyzes the McCabe complexity of your code and presents the complexity of each code element, letting you easily identify code with high complexity.
- RVS Treemaps present the hierarchy of your code’s components and source files graphically.
- RVS lets you view and explore the call dependencies in your code.

How does RVS supplement my Simulink model-based development workflow?
RVS can supplement model-based development workflows using MATLAB® Simulink® to support on-target verification of model-based code and verification of handwritten code.
RapiCover supports generating structural coverage metrics for model-based code in SIL, PIL and HIL testing environments, while RapiTime supports execution time analysis including WCET analysis of model-based code from on-target testing in PIL and HIL environments.
RVS can be used to support functional testing, structural coverage analysis and execution time/WCET analysis of additional handwritten code used in projects that use Simulink.
