TASKING and WITTENSTEIN high integrity systems Partner to Simplify Timing Analysis

TASKING and WITTENSTEIN high integrity systems (WHIS) have announced a collaboration to enable software-based timing analysis for embedded systems. The partnership integrates TASKING SWAT with SAFERTOS, allowing developers to verify timing constraints without relying on hardware-based trace tools.

This integration utilizes TASKING SWAT, a software-based tracing solution designed for real-time profiling. By combining this tool with SAFERTOS, developers gain direct visibility into runtime behavior and scheduling analysis. This approach enables the monitoring of execution timing and task deadlines through software, bypassing the physical trace hardware typically required to capture such data accurately.

The Challenge of Timing Verification

In the development of safety-critical systems, timing analysis is a non-negotiable requirement. Engineers must prove that every critical task meets its deadline to prevent system failure in high-stakes environments. Traditionally, achieving this level of precision required expensive, specialized hardware trace tools that could monitor the processor's internal state without interfering with the software's execution. While accurate, these tools add significant cost and complexity to the development environment.

Impact on Safety-Critical Development

Removing the dependency on hardware-based trace reduces the financial and technical barriers in the development cycle of safety-critical software. By shifting the profiling capability into the software layer via TASKING SWAT, companies can streamline their verification workflows. This shift is particularly relevant for the automotive and industrial sectors, where the complexity of embedded software is increasing and the pressure to reduce time-to-market is intensifying.

Future Outlook

As embedded systems grow more complex, the move toward software-defined verification tools suggests a broader trend of reducing hardware overhead in the QA process. Industry observers will be watching to see if this software-based approach becomes the standard for certification in highly regulated environments. While the core functionality of scheduling analysis and real-time profiling is confirmed, the long-term adoption rate will depend on how these software tools perform across different processor architectures. This transition toward software-centric profiling could fundamentally change how engineers approach the validation of real-time operating systems, potentially democratizing high-integrity development for smaller firms that previously lacked the budget for high-end hardware trace infrastructure.
