The hidden flaw in real-time systems teaching

May 18, 2026

Florent Goutailler, Associate Professor at Télécom Saint-Etienne, describes how adding a runtime visualisation tool to his FreeRTOS course closed that gap – and transformed the way his students approach engineering problems.

“For many years, I observed the same pattern: students could write code that compiled and ran, but when something didn’t behave as expected, they struggled to understand why.”

SOFTWARE ASSURANCE, OSSERVABILITÀ RUNTIME

May 5, 2026

Oltre la verifica statica: l’importanza del monitoraggio runtime nei sistemi edge critici per garantire sicurezza, resilienza informatica e successo operativo attraverso l’osservabilità continua. Read (In Italian) the Elettronica Oggi article on Percepio’s Continuous Observability.

Detecting silent failures and improving runtime security

May 5, 2026

Why are non-crashing failures becoming more common in modern embedded designs?
Embedded systems have become far more complex over the last decade. We now see multicore processors, RTOS-based concurrency, third-party middleware, connectivity stacks, and increasingly AI or data-driven workloads running alongside traditional control software.

Percepio Tracealyzer provided the scalability and modularity as key enablers for BMW engineers

May 5, 2026

“We do embedded software traces for automotive and other industrial software applications,” said Andreas Lifvendahl, CEO of Percepio. “We make sure the software behaves.” Tracealyzer provided insight into software runtime performance, helping engineers monitor execution behaviour during development and testing in BMW’s work on software-defined vehicles (SDVs).

Verifying multi-threaded embedded systems with software tracing

Apr 3, 2026

Embedded software often also needs to meet real-time requirements. For example, a control system might have a requirement to output control signals to a motor controller every 5 milliseconds, where any additional delay is considered a failure. Such requirements are not only affected by the execution time of the specific thread, but also by dependencies on other threads. Thus, verifying real-time requirements is about more than measuring timing metrics. It is also about identifying potential risks from thread interactions that may affect the timing requirements.

So, how do you verify that a design is good from a multi-threading perspective?

Elektor TV – Percepio’s founder Johan Kraft on edge observability, RTOSes, Percepio Detect and more

Apr 2, 2026

Stuart Cording at Elektor Magazine interviews Percepio’s Johan Kraft at Embedded World in Nuremberg 2026. Covring topics like Tracealyzer, Percepio Detect, and RTOS runtime debugging and wider edge observability challenges. The discussion reinforces a familiar challenge in embedded development: many of the hardest bugs are not easy to reproduce in a halted debugger. Better runtime observability helps teams see what the system was actually doing, when it mattered most.

A practical look at how WITTENSTEIN high integrity systems uses runtime visualization to improve reliability in safety-critical RTOS applications.

From code to behavior – Software assurance in safety- and mission-critical edge systems

Jan 15, 2026

Percepio’s CEO Andreas Lifvendahl appears as guest blogger in Military Embedded Systems. “In today’s defense and aerospace systems, the software stack is rapidly becoming as complex and as critical as the hardware it runs on. Modern edge platforms increasingly support multithreaded real-time applications, machine learning (ML) inference, over-the-air (OTA) updates, and third-party integrations.

Consider a defense avionics application running on a partitioned embedded platform with mixed-criticality workloads. In the lab, the system passes all static checks and unit tests. However, during field trials, a subtle race condition causes periodic latency spikes in a mission-critical control loop – an issue never observed in simulation or test environments.”

From Bottlenecks To Breakthroughs

Dec 22, 2025

With the rising complexity of embedded systems and the difficulty in finding hidden bugs, observability tools seem to be the new alternative for developers. It shows what is happening in real time. What do the innovators say?

A Holiday Farewell: Reflecting on 40 Years in Embedded

Dec 22, 2025

The holidays are a time to slow down, take a deep breath, and prepare for the year ahead — and sometimes, for change. To that end, I’ve decided that after 40 years, it’s time for me to say goodbye to the embedded industry at the end of December. In 1983, I dropped out...

Continuous Observability in Automotive Development

Dec 8, 2025

As the automotive industry advances toward increasingly software-defined vehicles, the complexity of embedded systems is rising dramatically. From electrified powertrains to autonomous features and over-the-air updates, modern vehicles now function as distributed computing platforms with strict real-time constraints and safety-critical responsibilities.

In this landscape, ensuring software correctness, reliability, and traceability is no longer a late-stage testing concern, it must be a continuous effort. This is where the concept of continuous observability becomes essential.
