Trusted by the best, globally
Why use RapiTime?
RapiTime helps teams working on embedded and safety-critical systems gain deep insight into timing behavior, optimize performance, and meet certification goals with confidence.
- Supports compliance with DO-178C (including DAL-A) and ISO 26262, making it suitable for high-assurance software development.
- Automatically analyzes key timing metrics, including worst-case execution time (WCET), on-host and on-target for C, C++, and Ada code.
- Streamlines timing verification by automating instrumentation and metric collection, reducing manual effort and improving accuracy.
- Offers flexible integration strategies to suit your hardware and development environment.
- Includes advanced features to pinpoint optimization opportunities and investigate rare timing events, with qualified instrumentation that has saved customers like Collins Aerospace significant engineering time.
Success Story
Automating WCET Analysis for Flight Control Software on the M-346
"With RapiTime, we discovered the possibility to reduce by 10% the time spent by a Computer Software Configuration Item"
Alenia Aermacchi
Success Story
WCET and worst-case stack usage analysis on Embraer's DO-178B Level A flight control system
"We have successfully shown the viability of using RapiTime to measure WCET. It was able to support our hardware platform and once the system was set up, the analysis method could be repeated with relative ease.”
Embraer
Success Story
Worst-case execution time optimization on the Hawk Mission Computer with RapiTime
"We are delighted with the schedule reductions achieved in phase 1. The integration team are now looking at how RapiTime can be used as an integral part of the software development process for future Hawk developments.”
