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. 

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.

We have been providing quality products and customer service to companies primarily in the aerospace and automotive embedded industries since 2004, as demonstrated by our case studies. As our products are designed to meet the stringent requirements for DO-178B/C certification in the aerospace industry, they are well-suited to any safety/mission-critical application such as those in the nuclear, medical, industrial and rail industries.

You can request a trial version of RVS. You can also arrange a demonstration, where a member of our team will work with you to show the benefits RVS can offer you.

The design requirements of all RVS tools include the ability to work alongside your existing development environment. You can configure these tools to generate verification metrics and run tests using custom scripts, and can integrate the tools into your existing version control and continuous build systems. 

All RVS tools support numerous data collection strategies, which are optimized to achieve a minimal instrumentation overhead. You can collect data using debuggers, logic analyzers, directly from the address bus, or using our datalogger, RTBx. By working with you to determine the optimal data collection strategy, we can together ensure that you achieve results with minimal effort.

All our RVS tools are designed to meet the most stringent needs of certification processes, such as the DO-178B/C process used in the aerospace industry and the ISO 26262 process used in the automotive industry. We can provide developer qualification documents, a template integration qualification report and on-site tests to support you in qualifying RVS tools in projects requiring certification.

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. 

RVS tools support Windows 7 or newer, Windows Server 2008 R2 or newer, and a variety of Linux distributions including Ubuntu and Red Hat.

RVS tools can be used on projects with unsupported operating systems by using a clone integration to split the process and delegate parts of it to the unsupported machine.

All RVS tools can be integrated to work with almost any compiler and target hardware. Our integration service promises to deliver a robust integration of RVS into your build system.

RVS tools can be integrated to work with almost any embedded target. Our engineers can work with you to determine the optimal strategy for integrating the tool with your target, even for multi-core architectures. For more information on the hardware architectures we have integrated RVS tools with, see the compatibility information on our RVS product pages.

RVS supports C, C++ and Ada projects, including mixed-language ones.

All RVS tools include a friendly user-interface that presents your results in both tabular and graphical formats. Using this interface, you can filter your results to zoom in on target functions, making it easy to find the information you are looking for.

You can view RapiTest, RapiCover and RapiTime results (and results for zero-footprint versions) in continuous integration software, allowing you to track your verification results over time. 

RVS tools are designed to handle very large code bases. Because of the efficient algorithms used by RVS tools, there is no fundamental limitation to the number of lines of code that RVS can process, and our RVS tools have been used on projects with millions of lines of code.

We offer both “Node-locked” and “Floating” licenses, and a license server to support use of our tools in your specific development environment. 

For more information on our licensing models, see our RVS licensing FAQs.

All RVS licenses include access to our dedicated in-house support team, who will work with you to provide a rapid fix to your issue. This is a critical part of our vision. During 2021, we resolved 63% of our support requests within 7 working days and 93% within 30 working days. We also inform our customers of known issues via our website and email.

We provide an extensive set of RVS documentation with each of our products, and offer training courses guiding you through the most effective use of RVS tools. All our users can benefit from privileged access to our website, which includes downloads for new product releases. 

RVS integrates with a range of continuous integration tools, allowing you to collect unit test, coverage and execution time results with every new build, track your verification progress over time and easily identify anomalies in your software's behavior as they are introduced.

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. 

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.

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.

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.

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.

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.

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.

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.

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.

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.
