Partnership - GLIWA
ETAS & GLIWA optimize AUTOSAR Classic ECU performance
The ETAS and GLIWA partnership makes ECU runtime behavior measurable and optimizable. By combining our AUTOSAR Classic platform RTA-CAR with the GLIWA T1 Analysis Suite, engineers gain evidence-based optimization through tracing and analysis integrated directly into the AUTOSAR Classic toolchain.

Your challenges
Unreliable timing
Ensuring compliance for overall CPU load, deadlines, interrupt latencies, and scheduling effects (e.g., jitter) in AUTOSAR Classic projects is complex.
Hidden issues
Suboptimal configuration choices often remain undetected until late in the integration and testing process, leading to costly missed deadlines and hardware upgrades.
Resource overload
Managing memory efficiency (stack/heap, leaks, allocation patterns) and MPU configuration/issues is critical for runtime robustness.
ETAS & GLIWA: Integrated tracing and analysis workflow
ETAS and GLIWA deliver a robust, integrated, tracing and analysis workflow to tackle your timing and resource challenges head-on. Our seamless integration of RTA-CAR and T1 empowers engineers to move from guesswork to evidence-based optimization:
- Automated integration: GLIWA T1 tracing is highly automated through a guided setup process, dramatically cutting down manual scripting and configuration.
- Comprehensive runtime transparency: Visualize task switching, interrupt latencies, and scheduling details to pinpoint bottlenecks and timing violations effectively.
Your benefits
Precise analysis
Precisely visualize task switching, interrupt latencies, and scheduling details of your AUTOSAR applications.
Deep memory insight
Monitor stack and heap consumption in real-time. Identify memory leaks, avoid MPU exceptions, and optimize allocation - before they become critical issues.
Immediate bottleneck detection
Thanks to detailed trace information, instantly see which code sections are slowing down your ECU for targeted optimization.
Reduced hardware costs
Achieve a considerable reduction in stack consumption by identifying cooperative multitasking, potentially avoiding expensive hardware upgrades.
Features and functionalities
GLIWA T1 tracing is highly automated through a guided setup process, dramatically cutting down on manual scripting and configuration. This integration into the ETAS RTA-CAR AUTOSAR Classic toolchain is visually represented by the direct connection between the RTA-CAR stack and the T1 component in the architecture diagram.
Provides comprehensive visualization of task switching, interrupt latencies, and intricate scheduling details, enabling engineers to accurately pinpoint performance bottlenecks and critical timing violations within the ECU, facilitated by GLIWA T1's timing measurements and real-time visualization features.
Real-time monitoring of stack and heap consumption, allowing for the immediate detection of memory leaks, avoidance of MPU exceptions at build-time, and optimization of allocation patterns to prevent critical issues and improve resource efficiency.
The combined solution supports analysis beyond development environments, extending to HIL, test vehicles, and production vehicles, leveraging T1’s ISO 26262 ASIL-D certification for critical runtime analysis, with optional cloud connection capabilities. This certification is prominently featured in the provided image.
