PowerTrace III


High-Performance Parallel Trace Extension

Our high-performance PowerTrace III trace module is the best trace tool available for parallel trace ports, letting you get the maximum data throughput out of your device. With its high speed, large memory buffer, and support of almost any CPU, you are able to record system behavior in real time without influencing the system operation. PowerTrace III uses the PodBus Express port of your existing PowerDebug X50 to expand your system capabilities. Migration to a new architecture requires minimal change due to the modular design of preprocessors and connectors.


Win the Race with Trace

Real-time trace dramatically improves your ability to debug and analyze your embedded system. Embedded projects benefit from measuring execution performance, analyzing race conditions, or proving code coverage. By using PowerTrace III for parallel trace, you will quickly locate and fix bugs to keep up with the ever-hastening development cycle pace. It captures the comprehensive run-time behavior of your embedded system to find glitches even if they only appear in real time.

Keep Up with Modern Multi-Core Devices

Store data from multiple cores simultaneously in the large high-speed buffer (up to 8 GB) of the PowerTrace III. With its maximum recording speed of 19.2 Gbit/s, PowerTrace III is suitable for state-of-the-art and future processor speeds.

Use Any Available Trace Protocol

PowerTrace III can handle a wide range of standard and proprietary trace protocols for both system-level and program flow traces. These include ETM, PTM, Nexus, MCDC, SWV, TWP, STP and more.

Ultra-Long Trace Lets You Capture Everything

Capture extremely long-term trace recordings by streaming trace data to your host PC for later analysis. An average streaming rate of 400 MB/s ensures reliable transfer without data loss. Even higher trace rates may be achieved and are handled reliably by the PowerTrace III internal high-speed memory buffer.

Trace Outside The Box

PowerTrace III provides a complete view of your embedded system beyond the confines of your SoC core. The Mixed-Signal Probe augments your PowerTrace III by recording external digital and analog signals and correlating them exactly to the traced program execution. This provides crucial insight into any external, real-time behavior that affects your code execution.

1The average streaming rate defines the amount of data which can be transferred on the fly to the PC per second. If the trace-port rate is below that streaming rate in average, a practically infinite recording time is possible. The peak-rate is possible temporarily and is compensated by the internal memory of the PowerTrace extension.

2We specify here the speed of the serial link. The maximum speed for the transferred payload is usually smaller due to line encoding, e.g. 80 % with 8b/10b encoding.

3 Requires serial preprocessor. For serial tracing we recommend PowerTrace Serial.

4The streaming rate defines the amount of data which can be transferred on the fly to the PC per second. If the trace-port rate is below the streaming rate in average, a practically infinite recording time is possible.

Maximize Bandwidth with Autofocus Technology

To connect your target’s trace port to the PowerTrace III, you need a platform-specific trace probe, because trace ports come in all shapes and sizes. Depending on your use case, a trace probe for the PowerTrace III is called a Preprocessor or Nexus Adapter.

Our Preprocessor’s AutoFocus technology automatically adjusts the sampling point for every signal of your parallel trace port independently from one another. This results in more reliable trace capture with less concern about board routing and length matching.
