OVERVIEW

Cost-Effective Parallel Trace Extension

Our cost-effective PowerTrace II Lite trace module is well suited for mid- and low-speed cores implementing parallel trace ports and lets you record system behavior in real-time without influencing the system operation. PowerTrace II Lite uses the PodBus Express port of your existing Power Debug X50 to expand your system capabilities. Migration to a new architecture involves minimal changes due to the modular design of our preprocessors.

BENEFITS

Every Project Can Benefit from Real-Time Trace

Real-time trace dramatically widens the capabilities to debug and analyze your embedded system. Even projects with small and mid-performance SoCs and a small code base benefit from measuring the execution performance, analyzing race conditions, or proving code coverage. Despite its reduced trace bandwidth compared to PowerTrace III, PowerTrace II Lite comes with the full set of our world-renowned analysis features found in our most powerful trace modules.

Use Any Available Trace Protocol

Store data from multiple cores simultaneously in 1 GB of high-speed memory. With a maximum recording speed of 10 Gbit/s, your PowerTrace II Lite is suitable for many of today’s processor speeds.

Keep Up With Modern Multicore Devices

Store data from multiple cores simultaneously in 1 GB of high-speed memory. With a maximum recording speed of 10 Gbit/s, your PowerTrace II Lite is suitable for many of today’s processor speeds.

Great Value for Your Money

PowerTrace II Lite is a cost-effective solution for trace applications on all but the fastest high-end processors and where the usage of our Mixed-Signal Probe is not essential. Nevertheless, it provides our full set of analysis features.

Trace Ultra Long to Capture Everything

Capture extremely long-term trace recordings by streaming the trace data to your host PC for later analysis. An average streaming speed of 100 MB/s ensures a reliable transfer without data loss in many use cases. Higher momentary trace rates are possible and are handled reliably by the Power Trace II Lite’s internal high-speed memory.

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.

²Requires Preprocessor. Pin- count and recording- speed depends on used preprocessor and trace protocol

³ Speed of the serial link is specified. The maximum speed for the transferred payload is usually smaller due to line encoding, e.g. 80% with 8b/10b encoding.

⁴ Requires serial preprocessor. For serial tracing, we recommend PowerTrace Serial.

⁵ CombiProbe 2 works with PowerDebug E50, X50, E40, PRO, USB 3, II. Not supported are PowerDebug Ethernet, USB, or USB 2.

⁶ PowerTrace extensions work with PowerDebug X50, PRO, II.

⁷ Requires Preprocessor

⁸ PCIe Gen.4 (16 Gbit/s) requires Preprocessor (available in Q2/2023).

TARGET CONNECTION

Maximize Bandwidth with AutoFocus Technology

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

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