We create efficient and cost-effective tools for software developers working on high-integrity aerospace applications at civil and military aerospace manufacturers around the world. Their need for accurate verification tools has never been higher.
RVS Aero helps engineers meet the demanding verification requirements associated with DO-178B/C or equivalent military standards in systems ranging in complexity from simple cyclic systems up to ARINC-653 partitioned operating systems.
Aerospace applications are typically designed to satisfy DO-178B/C guidance and many are built to an IMA architecture using ARINC-653 systems powered by the most advanced microprocessors available. While weight reductions and maintenance savings are a key objective of complex software architectures, these technology trends make the timing behaviour of already complex aerospace systems more difficult to analyze.
As a consequence, interest in engineering approaches and tools that can aid quick detection and analysis of potential timing problems during development is on the increase. At the same time, the increasing complexity of avionic systems leads to an increasing demand for low overhead solutions for measuring coverage on-target.
RVS Aero tools increase the efficiency of testing processes, aid identification of performance bottlenecks, and are designed for the typical resource constrained embedded environment.
RapiTestAero is a testing framework designed for unit and integration testing. RapiTestAero reduces the effort needed to apply requirements-based tests to your code by automating test harness generation, execution, and results collection.
With its powerful test formats, RapiTestAero reduces the time it takes to write test cases. RapiTestAero lets you run tests as part of a continuous build environment on either a host computer or your test rig, so office hours don’t delay your project.
Off-the-shelf qualification kits and a qualified target integration service will help you on the road to qualifying your use of RapiTestAero in DO-178/ED-12C projects.
RapiCover Aero is specifically designed to meet the challenges of verifying aerospace software written in Ada, C and C++ for critical embedded systems. The tool collects structural coverage measurements from software tests run on host computers, simulators or the embedded target itself.
By integrating seamlessly with your native build system, RapiCoverAero lets you collect verification data automatically, for example in continuous build environments. Compared to similar tools on the market, RapiCoverAero has extremely low overheads, so coverage data can be collected in fewer test runs.
RapiCoverAero meets the needs of DO-178C/ED-12C certification by collecting statement, decision and modified condition/decision coverage data; see the table below. RapiCoverAero analysis supports both interpretations of "decision" defined by CAST-10. The high-quality qualification kits available for RapiCoverAero provide the evidence needed to qualify the tool for DO-178C/ED-12C projects.
RapiTime Aero is designed to meet the challenges of verifying aerospace software written in Ada, C and C++ for critical embedded systems. The tool collects execution time measurements from software tests run on host computers, simulators or the embedded target itself and reduces the cost and effort needed to analyze execution time behavior, optimize software and update legacy systems.
By integrating seamlessly with your native build system, RapiTimeAero lets you collect verification data automatically, for example in continuous build environments. Compared to similar tools on the market, RapiTimeAero has extremely low overheads, so you can collect verification data in fewer test runs.
RapiTimeAero's qualification kits provide evidence needed to qualify the tool for use in DO-178C/ED-12C projects.
RapiTaskAero helps embedded aerospace engineers understand the scheduling behavior of their Ada, C and C++ software. The tool collects data on task-level scheduling behavior when software tests are run on host computers, simulators or the embedded target itself, and provides a variety of displays, charts and graphs to help you analyze the data.
By integrating seamlessly with your native build system, RapiTaskAero lets you collect task-level scheduling data automatically, for example in continuous build environments.
RapiTaskAero can be used to demonstrate scheduling behavior of complex applications used in aerospace electronics, for example those using an ARINC-653-compatible RTOS.
The information reported by RapiTaskAero provides evidence to support DO-178C certification, for example items:
6.3.2c: Compatibility with the target computer:"... especially the use of resources such as … system response times."6.3.3c: Compatibility with the target computer:"... asynchronous operation, synchronization, and interrupts…"6.4.2.2e:"A check should be made to ensure that protection mechanisms for exceeded frame times respond correctly."
