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

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

If you’re interested in RapiTask in academia, you can search for it in the academic press.

RapiTask is the leading tool for task-level scheduling analysis of critical software.

Used globally in the aerospace and automotive industries, it reduces the cost of understanding software scheduling behavior and troubleshooting scheduling issues.

As part of the RVS toolsuite, it forms part of a software verification solution that also includes tools for functional testing, structural coverage analysis and worst-case execution time analysis. 

RapiTask provides an RTOS-independent tool for visualization and exploring the scheduling behavior of embedded systems, and rapidly diagnosing and identifying potential problems.

It lets you visualize scheduling behavior across threads and processor cores, and reports response times from your system.

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.

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.

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

RapiTask displays results in two applications, the RVS Project Manager that is shared with all RVS tools, and an application specifically designed to display task scheduling information. You can synchronize the two applications to ensure that you can easily identify specific timing events in your system. 

RapiTask's Invocation Timeline Chart helps you to understand the high-level scheduling behavior of your system at a glance. 

As with all RVS tools, RapiTask supports data collection on multicore architectures. 

RapiTask is a component of Rapita's MACH¹⁷⁸ solution and Multicore Timing Solution, which analyze the timing behavior of multicore systems.

RapiTask is OS-agnostic so you can keep the same visualization and metrics if you change OS, and you can use RapiTask results as a point of reference to compare operating systems.

Additionally, you can capture and display custom events not related to the operating system (for example ARINC 429 messages) and display them in the trace.

You can use RapiTask as a standalone tool with either automatic or manual instrumentation.

RapiTime abstracts away from the OS tasking model and only reports the execution time of a task as if it were the only thing running on the CPU. If you are interested in the response time of your code, or the interaction between tasks and your OS, you'll need RapiTask.

RapiTask is OS-agnostic; as with all Rapita tools the integration with the operating environment needs to be customized. If we can get information about items of interest from the OS we can add ‘user events’ to a RapiTask trace.

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. 

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.
