Verifying multi-threaded embedded systems with software tracing

Verifying multi-threaded embedded systems with software tracing

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

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.

Seeing Inside the Scheduler

RTOS applications rarely fail because a single task is misbehaving. Instead, problems emerge from interactions that are often invisible at the code level.

Max Maxfield – “Well, Fork Me with a Dining Philosophers Problem”

One question I’m often asked—and one I often ask myself—is, “How many people are currently involved in developing embedded systems?” Counting engineers is a slippery problem (especially mechanical engineers, because they are often dripping in oil). I’d hazard a guess that there are probably between 2 and 4 million embedded professionals globally (depending on how we define ‘embedded’ and ‘professionals’), including both hardware designers and software/firmware developers.

Now I have another question for you. How many embedded system development teams around the world are using the tools from Percepio? The answer to this one is easy: “Not as many as there should be!”

Percepio Detect 2025.2 Makes Firmware Freezes Visible

Percepio Detect 2025.2 Makes Firmware Freezes Visible

New Percepio Detect 2025.2 release delivers faster debugging, smaller core dumps, expanded IAR Embedded Workbench® and Arm support, and TaskMonitor for automatic anomaly detection. Percepio Detect builds on Percepio’s self-hosted observability platform, offering unlimited on-device monitoring with “security-camera-style” trace capture that records only when unusual events occur.
