Worst-case Validator

chronVAL is a worst-case analysis tool. It enables users to analyze, optimize and validate single-core, multi-core, multi-processor and distributed embedded systems with regard to worst-case scenarios. The integrated design, diagnosis and test abilities allows architects to analyze the worst-case behavior of embedded systems and bus communication. Due to state of the art algorithms, chronVAL delivers precise, meaningful results very fast. With increasing complexity of modern systems, chronVAL brings significant time and detail advantages in comparison with existing tools.

Are you sure your system works correctly under worst-case conditions?

Figure it out with chronVAL

Select your view: single-core, multi-core, multi-processor, buses or distributed systems with several processors
Identify timing bottlenecks
Determine worst-case: end-to-end timings, task suspension times, bus and CPU loads
Analyze worst-case latencies of event chains (end-to-end timing from sensor to actuator)
Determine worst-case bursts on buses (e.g. Ethernet, CAN, FlexRay dynamic part)

chronVAL the essential and vital tool for

System and software architects of real-time critical systems
Safety engineers
Timing engineers
Test engineers

chronVAL the best tool to

Design robust, scalable and efficient dynamic system and software architectures for worst-case conditions
Ensure the worst-case for safety critical systems (e.g. IEC61508, ISO26262, DO-178B)
Validate the real-time compliance with cutting-edge mathematical algorithms
Specify and validate best-case and worst-case time budgets of tasks, ISRs, software components, functions, inter core and inter processor communication
Safeguard end-to-end timing protection under worst-case conditions
Consider best-case and worst-case interrupt rates caused by sensors, peripherals or buses
Validate the worst-case behavior based on measurement traces
Design safety margin to avoid butterfly effects
Reduce the risk to fail already at the beginning
Make feasibility studies for new features/software components after change requests fast and easy

In a nutshell; save time, save money and relax. Worst-case will work!

chronVAL key features

Mathematical analysis of the real-time behavior
Verification of application deadlines
Validation of maximum message latencies
Evaluation of system performance
Graphical visualization of results
Abstract modeling of systems at task level
Validation of single and multi processor systems
Modeling of hierarchical scheduling methods (e.g. ARINC653)
