chronVAL
Worst-Case Timing Analysis

Model-based worst-case timing analysis of safety-critical embedded systems. Verification of system and software architectural design.

For software architects and functional safety engineers.

 

Detect Timing Bottlenecks and Violations Earlier

chronVAL allows you to analyze the real-time capability of safety-critical embedded systems using formal verification methods. Using an integrated software and hardware model, chronVAL calculates best and worst-case response times, preemption times, end-to-end latencies, and resource utilization.

Sensitivity analysis detects timing bottlenecks and sporadic violations, reducing the overhead of time-consuming implementations, integrations, and testing. Thus, for engineers and architects, chronVAL is a critical tool for assessing and optimizing design robustness and scalability.
